Problems solved by technology

[0018] In order to overcome the above-mentioned shortcoming of the prior art, a kind of fatty alcohol polyoxyethylene ether glycidyl ether preparation and its aftertreatment method have been developed. Compared with the existing technology, the present invention adopts a one-step method to prepare fatty alcohol polyoxyethylene ether glycidyl ether For crude ether, by adding a polymerization inhibitor during the end-capping reaction, on the one hand, it can reduce the problem of excessive color of the product caused by the self-polymerization of epichlorohydrin. On the other hand, it can also reduce the self-polymerization and product The problem of low yield and high product viscosity caused by polymerization with epichlorohydrin

Embodiment 1-1

[0067] 1.0gAlCl 3 , 100g magnesium silicate powder, add 5.6g concentrated hydrochloric acid and appropriate amount of water, knead and mix to form a semi-wet shape, which can be smoothly extruded into strips, which is the most suitable. Heating and dipping in an oil bath at 80-90°C for 24 hours, and then A single-screw extruder is used to extrude into a strip, then dried at 110° C., calcined at 450° C. in an air atmosphere for 2 hours, and sieved to obtain a treated magnesium silicate adsorbent of 100-200 mesh.

Embodiment 1-2

[0069] 3.0gAlCl 3 100g magnesium silicate powder, add 16g concentrated hydrochloric acid and appropriate amount of water, knead and knead to form a semi-wet shape, which can be smoothly extruded into strips. A screw extruder extrudes into strips, then dried at 110°C, calcined at 450°C in an air atmosphere for 2 hours, and sieved to obtain 100-200 mesh treated magnesium silicate adsorbent.

Embodiment 1-3

[0071] 5.0gAlCl 3 100g of magnesium silicate powder, add 27.8g of concentrated hydrochloric acid and appropriate amount of water, knead and knead, mix and bond into a semi-wet shape, which can be smoothly extruded into strips, which is the most suitable. Heating and dipping in an oil bath at 80-90°C for 24h, and then A single-screw extruder is used to extrude into a strip, then dried at 110° C., calcined at 450° C. in an air atmosphere for 2 hours, and sieved to obtain a treated magnesium silicate adsorbent of 100-200 mesh.

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: [0003] [0004] Introducing non-ionic oxyethylene chains into surfactants can improve the solubility of the surfactant and increase the stability of ion resistance. By adju...
