Abstract
The invention provides a preparation method for sorbitan trioleate, which includes the steps of adding a neutral catalyst, oleic acid and sorbitol in a reactor, increasing the temperature to a constant value, and performing a temperature-maintained reaction for a certain time until acid value is qualified, and decreasing the temperature and discharging the product. The sorbitan trioleate has a clear appearance and a light color, has good flowability, is stable in quality and is low in loss.
Description
Technical field
The present invention relates to tensio-active agent preparation field, particularly relate to the preparation method of a kind of SPAN85.
Background technology
SPAN85 is also called this dish 85, it is that sorbyl alcohol one anhydrates, two anhydrate thing and three molecule oleic acid form the mixture of ester, chemically structure is seen, this kind of tensio-active agent is the partial fatty acid ester of polyvalent alcohol, belong to nonionogenic tenside, it is water-in-oil or oil-in-water-type tensio-active agent that a class is excellent. Such tensio-active agent is widely used as emulsifying agent, lubricant, wetting agent, dispersion agent, thickening material etc.
SPAN85 generally has two kinds of production technique in traditional technology, a kind of employing two-step approach, sorbyl alcohol is become cyclic ethers under an acidic catalyst effect, then oleic acid is added and basic catalyst carries out esterification, this processing method preparation process is complicated, product there is a large amount of colloid generate, need to carry out except colloid, product loss is very big, 2nd kind of method adopts single stage method to use basic catalyst, sorbyl alcohol and oleic acid are directly thrown material, then heat up, etherificate and esterification carry out simultaneously, but still have sorbyl alcohol not carry out etherification reaction, the product appearance mobility of preparation is poor, muddy, product by product is more.
Summary of the invention
Provide the concise and to the point general introduction about the present invention hereinafter, so as to provide about the present invention some in basic understanding. It is to be understood that this general introduction is not that the exhaustive about the present invention is summarized. It is not key or the integral part that intention determines the present invention, and nor is it intended to limit the scope of the present invention. Its object is only provide some concept in simplified form, in this, as the preorder in greater detail discussed after a while.
In order to overcome the above problems, the present invention provides the preparation method of a kind of SPAN85, and described preparation process is: by neutral catalyst, oleic acid adds reactor together with sorbyl alcohol, be warmed up to insulation reaction for some time after fixed temperature, until acid number qualified after, cooling discharge.
In described preparation method, temperature of reaction is 210-230 DEG C.
In described preparation method, the reaction times is 5-7 hour.
In described preparation method, the feed ratio of sorbyl alcohol and oleic acid is 1:1-1:2.
In described preparation method, the consumption of neutral catalyst is the 0.3%-1% of sorbyl alcohol weight.
The present invention has following useful effect:
The present invention adopts new neutral catalyzer, and etherification reaction and esterification are all had catalytic, and SPAN85 clear appearance prepared by the method adopting the present invention, and product color is shallow, good fluidity, steady quality, and product loss is little.
