Abstract

The invention provides a preparation method of alkyl glycidyl ether. The preparation method comprises the following steps: carrying out the following continuous flow substitution reaction on alkyl alcohol and epoxy halogenated propane in a micro-channel reactor to obtain alkyl glycidyl ether; wherein the alkyl alcohol comprises one or a mixture of more of compounds CnH<2n+1>OH shown as a formula I, and n in the formula I is 12-14; the epoxy halopropane has a structure shown as a formula II, and X in the formula II is a halogen atom. The invention solves the problems that in the prior art, whenalkyl glycidyl ether is prepared, reaction safety is poor, the number of byproducts is large, and the product yield and purity cannot be considered at the same time; the preparation method is simplein operation process, high in product purity, efficient, safe, environmentally friendly and suitable for industrial production.

Description

technical field

[0001] The invention relates to the technical field of organic synthesis, in particular to a preparation method of alkyl glycidyl ether. Background technique

[0002] UV-400 is a liquid ultraviolet absorber with excellent performance, mainly used in high-performance coatings and automotive paints, its structure is as follows:

[0003]

[0004] UV-400 was first successfully developed by Ciba. The two raw materials used in its synthesis are 4,6-bis(2,4-xylyl)-2-(2,4-dihydroxyphenyl)- 1,3,5-triazine, the other is a mixed long carbon chain alkyl glycidyl ether, namely C 12 -C 14 Alkyl glycidyl ether, UV-400 synthetic route is as follows:

[0005]

[0006] Therefore, want to industrialize the production of ultraviolet absorber UV-400, C 12 -C 14 The production technology of alkyl glycidyl ether must be overcome.

[0007] Currently reported C 12 -C 14 The synthetic method of alkyl glycidyl ether is less, as reported a kind of C in the patent CN1014400...
