Embodiment 1

[0015] Example 1: Add 50 parts of sorbitol polyoxyethylene ether and 47 parts of oleic acid by weight in the reaction kettle, add 0.4 parts of p-toluenesulfonic acid catalyst under stirring, gradually heat up, and under vacuum state, the reaction conditions at a temperature of 170 ° C Under heat preservation for 8 hours, the temperature was lowered, and the yield was 96.5%.

Embodiment 2

[0016] Example 2: Add 50 parts of sorbitol polyoxyethylene ether and 28.2 parts of oleic acid by mass into the reaction kettle, add 0.3 parts of tributyl phosphate catalyst under stirring, gradually heat up, and react at a temperature of 180 °C under vacuum Under the condition of insulation for 3 hours, the temperature was lowered, and the yield was 96%.

[0017] Its dehydration condensation reaction equation is in the above-mentioned embodiment:

[0018]

[0019] Note: RCOOH in the formula is oleic acid.

Abstract

This invention relates to a preparation method of sorbitol polyoxyethylene Oleate, belongs to organic esters compounds preparation fields. It takes sorbitol polyoxyethylene and oleic acid as raw material, is characterized by the organic acid catalyst or non-acidic catalyst role under dehydration condensation reaction, the product is sorbitol polyoxyethylene Oleate; sorbitol polyoxyethylene and oleic acid molar ratio of 1 : 3.9 ~ 4.2; organic acid catalyst is concentrated sulfuric acid or p-toluenesulfonic acid, non-acidic catalyst is tri-n-butyl phosphate(TBP) or titanium tetrabutoxide, its addition account for 0.2 to 1.5 percentage of total weight of sorbitol polyoxyethylene and oleic acid. This invention using organic acid catalyst or non-acidic catalyst for dehydration condensation reaction, the process is reasonable, simple operation, the deputy reactions is few. It can effectively reduce costs, increase yield.

Description

technical field [0001] The invention relates to a preparation method of sorbitol polyoxyethylene ether oleate, which belongs to the technical field of preparation of ester compounds in organic chemistry. Background technique [0002] Sorbitan polyoxyethylene ether oleate is a kind of nonionic surface active agent, is used as emulsifier in metal processing, and the synthetic method report of relevant sorbitan fatty acid ester is more, and sorbitol polyoxyethylene ether Oleate is less reported. Contents of the invention [0003] The purpose of the present invention is to provide a kind of technology reasonable, simple to operate, the preparation method of polyoxyethylene sorbitol ether oleate with good usability. [0004] The invention is a preparation method of polyoxyethylene sorbitol ether oleate, which uses polyoxyethylene sorbitol ether and oleic acid as raw materials, and is characterized in that the dehydration condensation reaction is carried out under the action of...
