Embodiment 1

[0050] 1000g of degummed jatropha oil, 120g of formic acid (80%), 33.5g of 50% sulfuric acid were added to a 2L glass kettle, stirred, and 452g of 37% hydrogen peroxide was added dropwise. After reacting for 4 to 10 hours, stand still and separate layers to separate the acidic water, use sodium carbonate aqueous solution to adjust the pH value of the oil phase, remove water in vacuum and filter. Obtain 1001 g of epoxy jatropha oil, and the epoxy value is 4.0%.

Embodiment 2

[0052] Add 1000g of refined jatropha oil, 230g of acetic acid, and 43.8g of 50% phosphoric acid into a 2L glass kettle, stir, add 471g of 35% hydrogen peroxide dropwise, and react for 4 to 10 hours at a temperature of 30 to 70°C. Set the layers to separate the acid water, adjust the pH value of the oil phase with an aqueous solution of sodium carbonate, remove water in a vacuum and filter. Obtain 996g of epoxy jatropha oil, and the epoxy value is 3.92%.

Embodiment 3

[0054] Add 1000 g of epoxy jatropha oil, the product in Example 1, into a 2L glass kettle, then add 233 g of propylene glycol and 7.9 g of potassium hydroxide, stir and heat up, control the reaction temperature at 65-170° C., and the reaction time for 5-10 hours. Add 252g of glycerol, control the temperature at 120-240°C, carry out the alcoholysis reaction for 4 hours, and then remove small molecules in vacuum, and analyze the crude product with a hydroxyl value of 497mgKOH / g. After refining, 1389g of refined bio-based polyols were obtained.

Abstract

The invention relates to the bio-polyol prepared by the Jatropha Curcasl oil by the following methods: the Jatropha Curcasl oil is added with the epoxidizing agent to conduct epoxidation reaction to produce epoxy Jatropha Curcasl oil under the condition that the catalyst exists; the produced epoxy Jatropha Curcasl oil conducts the epoxy bond addition reaction with the ring opening agent containing active hydrogen to produce the mixed hydroxyl fatty acid glyceride; after that, the alcohol or the alcohol amine are added and heated to carry out the alcoholysisreaction to produce the mixed hydroxyl fatty acid ester, namely the bio-polyol. The invention has the advantages that the inventions is high in reaction degree, wide in operation process range, convenient in control, higher in production functionality, convenient in raw material purchase and lower in cost, and does not fight for food with the people and is not affected by the petroleum resource, which is a green product optimizing the ecology. In addition, the invention also has the advantages of strong technology collectiveness and high product conversion.

Description

technical field [0001] The invention relates to a bio-based polyol prepared by adopting jatropha oil, which 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 prepare vegetable oil polyols for polyurethanes; or vege...
