Embodiment 1
[0048] In this example, erucic acid C22 was used as a starting material to prepare a C22 fatty alcohol polyoxypropylene polyoxyethylene block copolymer containing unsaturated double bonds. The specific operation is as follows.
[0049] 1. Esterification reaction
[0050] (1) Reaction formula:
[0051] CH 3 (CH 2 ) 8 =(CH 2 ) 12 COOH+CH 3 CH 2 OH→CH 3 (CH 2 ) 8 =(CH 2 ) 12 COOCH 2 CH 3 +H 2 o
[0052] (2) Specifications of raw materials:
[0053] Industrial-grade high-purity erucic acid C22:1 content>95%, iodine value (gI 2 / 100g) 80-90, water content 99.0%, water content <0.1%
[0054] (3) Raw material ratio:
[0055] Erucic acid: ethanol = 1:5 (molar ratio)
[0056] (4) Synthesis process:
[0057] Add erucic acid and ethanol into the reaction kettle according to the molar ratio of 1:5 (molar ratio). After the temperature is raised to 90°C, the reaction starts. During the reaction, ethanol is gradually added (the ethanol is sufficiently excessive to make ...
