Fatty alcohol-polyoxyethylene ether glycidyl ether and preparation method thereof

Abstract

The invention relates to fatty alcohol-polyoxyethylene ether glycidyl ether and a preparation method thereof and belongs to the technical field of fine chemical engineering. With fatty alcohol-polyoxyethylene ether and epoxy chloropropane being raw materials, the fatty alcohol-polyoxyethylene ether, a phase-transfer catalyst, alkali and a polymerization inhibitor are evenly mixed in a reaction kettle, then ECH is added, reaction is carried out for some time at certain temperature, solids are removed through filtering, liquid is subjected to reduced pressure distillation and recovery to be reactive ECH, the temperature is decreased to room temperature after completion, an absorbing agent, hydroxymethyl sodium sulfinate and water are added, adsorption and decoloring are carried out for some time at the temperature, heat-preserved dehydration is carried out for 1 h under the conditions of 110 DEG C and 0.098 Mpa, and then the finished product is obtained through filtering at the temperature of 80 DEG C. The preparation method is applied to preparation of the fatty alcohol-polyoxyethylene ether glycidyl ether, and has the advantages that the color of the product is light, and an epoxy value is guaranteed.

Description

technical field

[0001] The invention relates to a fatty alcohol polyoxyethylene ether glycidyl ether and a preparation method thereof, belonging to the technical field of fine chemicals. Background technique

[0002] Fatty alcohol polyoxyethylene ether glycidyl ether, with fatty alcohol as the initiator, epoxy addition to obtain fatty alcohol polyoxyethylene ether, and then obtain fatty alcohol polyoxyethylene ether glycidyl ether product through epoxy group capping, its The molecular structure features are: the middle part of the molecular chain is a polyoxyethylene ether chain, which has good flexibility and hydrophilicity, one end is an alkyl carbon chain, which is lipophilic, and the other end is an epoxy group, which has a good reactive active group. Group, the structural formula is as follows:
