Definitions
- the present invention relates to alkoxylates, including but not limited to alkoxylates of phenolic compounds, such as, branched and linear alkylphenols, napthtol and napthtol derivatives, bisphenols, branched and linear dialkyl phenols, benzene diols, benzene triols, phenolic resins, stilbene and its derivatives, and phenylphenol.
- phenolic compounds such as, branched and linear alkylphenols, napthtol and napthtol derivatives, bisphenols, branched and linear dialkyl phenols, benzene diols, benzene triols, phenolic resins, stilbene and its derivatives, and phenylphenol.
- the present invention further relates to alkoxylates of alcohols, polyols, fatty acids, amines, carboxylic acids, and any other potentially alkoxylated material and relates more particularly to certain derivatives of such alkoxylates useful as, for instance, surfactants in many varied industrial applications, and as intermediates from which can be prepared other related compounds having a variety of uses in the industrial and commercial arena.
- Alkylphenol alkoxylates and particularly alkylphenol ethoxylates, have found widespread use in a number of applications. These applications rely generally on the surfactant properties of such compounds.
- the surfactant properties can, in turn, be tailored by appropriate selection of the alkyl substituent on the phenol group, and of the number of repeating ethoxy units
- nonyl phenol ethoxylates are well known surfactants having a wide variety of uses; such compounds are known generically as "nonoxynol” compounds, and contain anywhere from 1 to 100 (or optionally more) repeating ethoxy units.
- the alkylphenol ethoxylates find widespread use in cosmetics, toiletries, and in such diverse industrial applications as oil slick dispersants, deinking surfactants, metal treating, textile treatment, emulsion formation, emulsion polymerization, detergents and related cleaners, and the like.
- alkyl phenol ethoxylates In view of the widespread use and wide variety of uses of alkyl phenol ethoxylates, coupled with the possibility that such ethoxylates may degrade, particularly biodegrade, into the corresponding alkyl phenol compounds or derivatives thereof which may prove to be estrogenic, the search for acceptable alternatives which would prove not to be precursors of possibly estrogenic materials has understandably led far afield of alkyl phenol alkoxylates.
- compounds having a hydrophobic moiety and a hydrophilic moiety in which the hydrophilic moiety is a polyethoxy chain such as alkyl phenol alkoxylates, but characterized in that 1) a short block of propoxy and/or butoxy unit(s) extends from the hydrophobic moiety and precedes the ethoxy chain, or 2) a short block of propoxy and/or butoxy unit(s) have been inserted into the ethoxy chain or 3) propoxy and/or butoxy unit(s) have been randomly inserted into the ethoxy chain, or 4) propoxy and/or butoxy unit(s) have been added to the end of the ethoxy chain, or 5) propoxy and/or butoxy unit(s) are substituted for the ethoxy chain, exhibit the highly desirable properties of reduced or no estrogenicity in themselves and their products of degradation.
- the present invention comprises in one aspect compounds of the formula
- A denotes a straight-chained or branched alkyl or alkenyl group containing 1 to 18 carbon atoms, a phenyl group, a phenyl-alkenyl group wherein the alkenyl moiety contains 1 to 4 carbon atoms, a polycyclic group containing 8 to 14 carbon atoms, a polyol, an alkoxy group, or hydrogen;
- D denotes phenoxy, oxy, phenyl, a linear or branched alkyl or alkenyl group, an amino group., or a carboxy group; x is 0 - 10; y is 1 - 10; z is 0 - 100;
- each (O-Alk) denotes straight-chained or branched propoxy, butoxy or substituted oxirane; and R is hydrogen, sulfate, sulfonate, mono and/or diphosphate, carboxylate, mono and/or disulfosuccinate, or a salt thereof.
- Yet another aspect of the present invention is in compounds of the formula A-D-(0-Alk) y -OH, wherein A,D, (O- Alk) and y are as defined herein, and in their use as starting materials for synthesis of compounds of formula
- A-D-(OC 2 H 4 ) ⁇ -(0-Alk) y -(OC 2 H.) 2 -OR are useful in many commercial applications including surfactants.
- the present invention extends to such compounds per se as well as to any of the large number of end-use formulations which can contain one or more compounds of the formula.
- such formulations include oil field emuisifiers and
- A- ⁇ -D- represents more generally the hydrophobic portion of the compound in which D is substituted with 1 to 4 groups denoted as A.
- a 1 . 4 -D- can represent a wide variety of possible structures.
- A can be:
- alkenyl portion contains 1 to 4 carbon atoms, an example of which is benzyl;
- -a polycyclic group containing 8 to 14 carbon atoms which can be wholly saturated, fully unsaturated, or partially saturated and partially unsaturated, such as indanyl, naphthalene, dihydronaphthalene, tetrahydronaphthalene, and analogs thereof containing cyclohexyl, cyclohexenyl, cyclopentyl or cyclopentenyl in place of the phenyl ring;
- - hydroxyl or polyol preferably containing 2 to 6 carbon atoms and 2 to 6 hydroxyl groups; or alkoxy, preferably straight-chained or branched and containing 1 to 20 carbon atoms.
- D can be phenoxy, oxy (that is, -0-), phenyl, a straight-chained or branched alkyl or alkenyl group containing 1 to 18 carbon atoms, an amino group, or carbonyl (that is, -C(O)-).
- Preferred A 1-4 -D- groups include hydroxy benzylphenyl, i.e. a residue from Bisphenol A.
- Another preferred embodiment of the molecule there depicted is a phenyl ring which is substituted with one, two or three straight-chain or branched-chain alkyl and/or alkenyl groups containing 1 to 18 carbon atoms, or can be any of the other groups described herein.
- - A contains 4 to 12 carbon atoms.
- compositions containing two or more different compounds of formula (1) such as compositions containing more than one structural isomer of a compound having a given number of carbon atoms, as well as compositions containing compounds corresponding to two or more different versions of formula (1).
- the compound of formula (1) also contains a chain of 1 to 10 alkoxy units exhibiting the formula (O-Alk), wherein each (O-Alk) denotes a straight-chained or branched propyl, butyl or substituted oxirane moiety.
- O-Alk alkoxy units
- each (O-Alk) unit will be the same, although segments containing short blocks of poly (propoxy) and/or poly (butoxy) portions or random sequences of propoxy and/or butoxy groups are contemplated in the scope of this invention.
- the chain composed of repeating (O-Alk) units can be terminated with a segment of 1-100 ethoxy units which is itself optionally substituted.
- the number of repeating ethoxy units can be chosen in conjunction with the number of carbon atoms in the segment A so as to afford the desired degree of solubility in the intended medium, and to afford the desired HLB (hydrophilic-lipophilic balance (reference: Griffin, W.C, J. Soc. Cosmetic Chemists, vol. 1 (1949), p. 311), as is well known in the surfactant art. Random mixtures as well as blocks of ethoxy and propoxy and/or butoxy units are also contemplated in the scope of this invention.
- the poly(ethoxy) capped alkyl phenol alkoxylate can be capped simply with a -H group, thereby affording a useful nonionic surfactant.
- the compound of formula (1) can be capped with an anion such as a sulfate, sulfonate, carboxylate, phosphate group or sulfosuccinate, and salts thereof, thereby forming a useful series of anionic surfactants.
- the anionic group can be balanced in charge by a cation M such as sodium, potassium, lithium, ammonium, or amine salt among others or left in its acid form.
- a cation M such as sodium, potassium, lithium, ammonium, or amine salt among others or left in its acid form.
- the particular choice of nonionic surfactant and anionic surfactant groups is well within the ability of the formulator.
- the nonionic surfactants according to formula (1), and the anionic surfactants according to that formula all have a wide variety of uses conforming to those uses known for conventional alkyl phenol ethoxylates, as well as alkyl phenol ethoxylate carboxylates, sulfates, sulfonates, phosphates, and sulfosuccinates.
- a significant aspect of the present invention is the applicants' discovery of methods by which alkyl phenol alkoxylates of formula (1) can be synthesized which in fact exhibit reduced or no estrogenicity in themselves and their products of degradation.
- the synthetic method resides in incorporating propoxy and/or butoxy units into the poly(ethoxy) segment. It will be recognized of course that there are several different synthetic pathways by which a desired insertion can be accomplished. For instance, in one preferred embodiment, a precursor of the formula
- the starting material A-D-OH is reacted with an already formed segment H(OAlk) y (OC 2 H 4 ) z OH, or in sequence with H(OAlk) y OH and then with H(OC 2 H 4 ) 2 OH, to form the final product.
- EXAMPLE 5 (p-octylphenol + 4 EO) 1.932 kg of octyi phenol and 10.8g of a 50% aqueous solution of sodium hydroxide were charged to a reactor, which was then purged, and heated to 125°C. This mixture was dehydrated at this temperature for two hours, following which 1.652 kg of ethylene oxide was added to the reactor and allowed to react at 125°C for one hour. The resulting mixture was neutralized and removed from the reactor. Results from the aforementioned standard test procedure indicated that this material is estrogenic.
- EXAMPLE 7 (ortho-nonylphenol + 4 EO) 1.989 kg of o-nonyl phenol and 10.8g of a 50% aqueous solution of sodium hydroxide were charged to a reactor, which was then purged, and heated to 125° C. This mixture was dehydrated at this temperature for two hours, following which 1.5959 kg of ethylene oxide was added to the reactor and allowed to react at 125°C for one hour. The resulting mixture was neutralized and removed from the reactor. Results from the aforementioned standard test procedure indicated that this material is estrogenic.
- Examples 9-12 describe synthesis of additional compounds to exhibit reduced estrogenicity and reduced tendency to degrade to estrogenic products .
- Examples 13 and 14 were carried out to enable a comparative assessment of estrogenicity to be made.
