Abstract
If chlorosilane is used in order to introduce a functional group into a silsesquioxane derivative having Si—OH, by-produced hydrogen chloride has to be treated. However, if alkoxysilane is substituted for chlorosilane, the long reaction time is required.
A production process for a silsesquioxane derivative represented by Formula (2) characterized by using a compound represented by Formula (1), has been developed in order to solve such problems of conventional techniques.
In Formula (1) and Formula (2), R is hydrogen, an alkyl, an aryl, or an arylalkyl; M is an alkaline metal atom; and X is hydrogen, chlorine, a functional group, or a group having a functional group.
Description
- The present invention relates to a production process for a silsesquioxane derivative having a functional group and a silsesquioxane derivative obtained by this production process.
- A silsesquioxane derivative has an excellent heat resistance and weatherability, and therefore it is expected to be applied to a modifier for a thermoplastic resin, a interlayer dielectric, a sealing material, a flame retardant and an additive for a coating material. It has so far been tried to introduce various functional groups into silsesquioxane. Disclosed in Literature 1 is, for example, a process in which a compound having Si—OH shown below is synthesized and in which various functional groups are then introduced by reacting the compound with chlorosilanes. Disclosed in Literature 4 is a process in which a small amount of a basic compound is added when a compound having Si—OH shown below is reacted with trialkoxysilane in an organic solvent.
- A in Formula (a) is the same group selected from hydrogen, methyl, ethyl, 2-methylpropyl, cyclohexyl, cyclopentyl, phenyl and vinylhexyl.
- The compound represented by Formula (a) can be synthesized by hydrolyzing chlorosilane and further ripening the mixture. Disclosed by Frank J. Feher et al. in California University is, for example, a process in which cyclopentyltrichlorosilane is reacted at a room temperature or a refluxing temperature in a water-acetone mixed solvent and in which the reaction mixture is further ripened for 2 weeks (Literature 2 and Literature 3).
- Literature 1: U.S. Pat. No. 5,484,867
- Literature 2: Organometallics, 10, 2526-2528 (1991)
- Literature 3: Chem. Eur. J, 3, No. 6, 900-903 (1997)
- Literature 4: U.S. patent application Ser. No. 2003/0055193 A1
- However, in order to industrially utilize them, the compound represented by Formula (a) can preferably be produced at a higher yield for shorter time with less by-products than those of such publicly known techniques. The process in which a functional group is introduced by reacting the compound represented by Formula (a) with chlorosilane has the industrial difficulty that by-produced hydrogen chloride has to be treated. Hydrogen chloride is not by-produced in the process of Literature 4, but it requires a very long reacting time. An object of the present invention is to provide a novel synthetic process for a functional group-containing silsesquioxane derivative and a novel compound obtained by this process in order to solve these problems.
- First, a term used in the present invention shall be explained. The term “optional” shows that not only the position but also the number is optional. When the number is plural, they may be replaced by different groups respectively. For example, when two of —CH2— are replaced by —O— or —CH═CH— in alkyl, alkoxyalkenyl and alkenyloxyalkyl are included in the alkyl. Alkyl and alkylene may be linear groups or branched groups in any cases. This shall apply when optional hydrogen is replaced by halogen or a cyclic group in these groups or when optional —CH2— is replaced by —O—, —CH═CH—, cycloalkylene or cycloalkenylene. Any group of alkoxy, alkenylene, alkenyl and alkylene may be either a linear group or a branched group in such case. It is not preferred in the present invention either that a plurality of adjacent —CH2— is replaced by —O— or that —CH2— bonded to a silicon atom is replaced by —O—.
- The present inventors have found a novel silicon compound represented by Formula (1) described later as an intermediate which can be used in order to achieve the object described above. The production process of the present invention is characterized by using the silicon compound represented by Formula (1) as the intermediate. According to this process, the reactivity is high, and less by-products are produced as compared with publicly known techniques. A novel silsesquioxane derivative is provided by the production process of the present invention. The silicon compound represented by Formula (1) can not be synthesized by the process of Feher described above. An example in which the compound represented by Formula (1) is used to synthesize a silicon compound represented by Formula (2) is not known as well. The present invention relates to a novel process in which the compound represented by Formula (1) is used to efficiently synthesize the compound represented by Formula (2).
- The present invention comprises the following structures.

- The silicon compound represented by Formula (1) shall be denoted by the compound (1) in the following explanation. The silicon compound represented by Formula (2) shall be denoted by the compound (2). The same shall be applied to the compounds represented by the other formulas.
-
- The compound (1) can readily be produced at a good yield by hydrolyzing a silicon compound having three hydrolyzable groups in an oxygen-containing organic solvent such as alcohol and ether in the presence of an alkaline metal hydroxide such as sodium hydroxide, and subjecting it to polycondensation. Success in synthesizing this compound (1) has made it possible to complete the production process of the present invention. That is, reaction of the compound (1) with the compound (3) has made it possible to easily synthesize for short time, the compound (2) into which X in the compound (3) is introduced. The compound (3) is chloride but may be other halide. X shall be described later.
- An organic solvent is preferably used for the reaction of the compound (1) with the compound (3). That is, the compound (1) is mixed with an organic solvent, and the compound (3) is dropwise added to this mixture, whereby the reaction goes on while by-producing chloride of alkaline metal. After finishing the reaction, water is added to dissolve the chloride described above and hydrolyze the unreacted compound (3). Then, the organic layer is separated from the mixture, and the solvent is removed by distillation, whereby the compound (2) can be obtained. The organic layer is washed with water and dried on a dehydrating agent before removing the solvent, whereby the compound having a high purity can be obtained. If the functional group introduced is a group reacting with water, the unreacted compound (3) and the organic solvent are advisably removed by distillation after removing the chloride by filtration. In either case, the purity can be enhanced by carrying out, if necessary, recrystallization.
- The solvent described above used in the reaction shall not specifically be restricted as long as it does not retard progress of the reaction. The preferred solvent includes aliphatic hydrocarbons (hexane, heptane and the like), aromatic hydrocarbons (benzene, toluene, xylene and the like), ethers (diethyl ether, tetrahydrofuran (THF), dioxane and the like), halogenated hydrocarbons (methylene chloride, carbon tetrachloride and the like) and esters (ethyl acetate and the like). These solvents may be used alone or in combination of a plurality thereof. More preferred solvents are ethers, and THF is most preferred. The compound (3) is readily reacted with water, and therefore the solvent having a very small moisture content is preferably used.
- A preferred proportion of the compound (1) in mixing with the solvent is 0.05 to 50% by weight based on the weight of the solvent. If it is 50% by weight or less, a concentration of the by-produced salts can be controlled so that it is not such high as retarding progress of the reaction. If it is 0.05% by weight or more, the volume efficiency can be prevented from being so deteriorated that an adverse effect is exerted on the cost. More preferred proportion is 1 to 10% by weight. A use amount of the compound (3) shall not be restricted as long as it is used in an equivalent mole or more based on the compound (1), but considering an after-treatment step, it is not preferably used in an excessive amount. The reaction temperature may be a room temperature, and heating may be carried out, if necessary, in order to accelerate the reaction. Further, cooling may be carried out, if necessary, in order to control heat generated by the reaction or undesirable reactions.
- This reaction can readily be accelerated by adding a compound having an amino group such as triethylamine or an organic compound showing basicity. To give an example in which triethylamine is used, a preferred use amount thereof falls in a range of 0.005 to 10% by weight, more preferably 0.01 to 3% by weight based on the weight of the solvent. However, an added amount of triethylamine shall not specifically be basically restricted as long as the reaction can readily be accelerated. A particularly excellent point of the production process of the present invention is a short reaction time. The reaction time after dropwise adding the compound (3) may be about one hour in almost all cases. The reaction is finished in about 3 hours at the longest.
