Biological radical polyatomic alcohol prepared by Jatropha curcas oil

Abstract

The present invention relates to a preparation method for a biological polybasic alcohol by using of an aleurites fordii. The preparation method is as follows: an alcohol-decomposing agent is added into the aleurites fordii to make the alcohol-decomposing reaction in the catalyzing environment to create a mixing ester of fatty acid; and then an epoxidizing agent is added into the mixing ester of fatty acid to make the epoxidizing reaction in the catalyzing environment to create a mixing epoxidizing ester of fatty acid; the mixing epoxidizing ester of fatty acid takes the opening reaction of epoxidizing key with an opening agent to create a mixing hydroxylic ester of fatty acid, i.e. a biological polybasic alcohol. The biological polybasic alcohol takes the addition reaction with an oxidation alkene in the catalyzing environment to create a biological polybasic alcohol with much higher molar weight. The preparation technics and operation of the present invention are more convenient; the adjustability for the product function is much better with much better performance. The aleurites fordii materials used in the present invention is a reproducible materials; so the cost is much lower and the material is abundant, which can replace the petrifaction polyether glycol to prepare the polyurethane foam plastic so that the dependence to the polyurethane product decreases.

Description

Bio-based polyol prepared from jatropha oil Technical field The invention relates to a bio-based polyol prepared by using jatropha oil for alcoholysis, epoxidation, ring opening and other reactions, and belongs to the field of organic synthesis. Background technique With the rapid development of the global economy, the global demand for all polyols is growing rapidly. The commonly used polyol is polyether polyol, and its preparation technology is well known. With the shortage of petroleum resources and rising prices, and at the same time, human beings pay more and more attention to the environment and hope to reduce their dependence on petroleum. The development of green, environmentally friendly and economical polyols has become an important direction of polyol development. At present, there have been some technical reports on polyols prepared from vegetable oils. For example, polyols such as glycerin are used for alcoholysis with vegetable oils, and then added with epoxides...
