Embodiment 1

[0051] Add 1000g of jatropha oil, 215g of glycerin, and 1.0g of potassium hydroxide into a 2L glass kettle, stir, raise the temperature to 160-240°C, carry out the alcoholysis reaction for 5 hours, and then keep it under the condition of vacuum degree of 100-750kPa 3h. Refining then, obtains 1185g of mixed fatty acid ester.

Embodiment 2

[0053]Take 1000 g of mixed fatty acid ester in Example 1, add 74 g of formic acid (85%), and 20 g of phosphoric acid into a 2L glass kettle, stir, add 507 g of hydrogen peroxide (27.5%) dropwise, and react for 8 hours at 30-70°C , After refining, a mixed epoxy fatty acid ester was obtained with an epoxy value of 3.41%.

Embodiment 3

[0055] Mix the product in Example 2 with 1000 g of epoxy fatty acid ester, then add 380 g of triethanolamine and 1.2 g of potassium hydroxide, add it into a 2L glass kettle, stir and raise the temperature, control the reaction temperature at 120-160°C, and the reaction time is 6h. After refining, 1280g of the bio-based polyol A product was obtained, the hydroxyl value was 490mgKOH / g, and the water content was ≤0.10%.

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

technical field [0001] The invention relates to a bio-based polyol prepared by using jatropha oil for alcoholysis, epoxidation, ring opening and the like, and belongs to the field of organic synthesis. Background technique [0002] With the rapid development of the global economy, the global demand for all polyols is growing rapidly. The commonly used polyols are polyether polyols, the preparation techniques of which are well known. Due to the shortage of petroleum resources and rising prices, at the same time, human beings are paying 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 for the development of polyols. [0003] At present, there are some technical reports on polyols prepared from vegetable oils, such as polyols such as glycerin and vegetable oils for alcoholysis, and then addition reactions with epoxides to prepa...
