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
The present invention relates to a kind of preparation method of sorbierite polyoxyethylene ether ester oleate, belong to the preparing technical field of ester compound in the organic chemistry.
Background technology
Sorbierite polyoxyethylene ether ester oleate is a kind of nonionic surface active agent, is used as emulsifying agent in metal processing, and the synthetic method report of relevant sorbitan fatty acid ester is more, and the sorbierite polyoxyethylene ether ester oleate report is then less.
Summary of the invention
It is reasonable to the purpose of this invention is to provide a kind of technology, simple to operate, has the preparation method of the sorbierite polyoxyethylene ether ester oleate of better use properties.
The present invention is the preparation method of sorbierite polyoxyethylene ether ester oleate, with sorbitol polyoxyethylene ether and oleic acid is raw material, it is characterized in that under the effect of organic acid catalyst or non-acidic catalyst, carrying out dehydration condensation, make sorbierite polyoxyethylene ether ester oleate.
The quantity of epoxy group(ing) can be 20～25 in the described sorbitol polyoxyethylene ether.
Described sorbitol polyoxyethylene ether and oleic mol ratio can be 1: 3.9～and 4.2.
Described organic acid catalyst can be the vitriol oil or tosic acid etc., and non-acidic catalyst can be tributyl phosphate or tetrabutyl titanate etc.
The add-on of described organic acid catalyst or non-acidic catalyst can be 0.2～1.5% of sorbitol polyoxyethylene ether and oleic acid total weight percent.
The temperature of reaction of described dehydration condensation can be 170～230 ℃, and the reaction times is 3～8 hours.
The present invention has following outstanding advantage and positively effect:
1, the dehydration condensation under employing organic acid catalyst or the non-acidic catalyst effect, technology is simple, and side reaction is few, can effectively reduce cost, and improves yield;
2, reaction conditions gentleness, institute's employing equipment is simple, thereby facility investment and energy consumption are more saved;
3, have characteristics such as emulsifying property, oilness are good by the sorbierite polyoxyethylene ether ester oleate of the present invention preparation, be applicable in fields such as high-speed spinning finish, metalworking fluids and use.
Embodiment
The quantity of sorbitol polyoxyethylene ether epoxy group(ing) is 23 in following examples.
