Abstract

The invention discloses a kind of preparation method of the butylene of 1 chlorine, 3 methyl 2, it is characterized in that, comprise the following steps, the alcohol of 3 methyl, 2 butylene 1 is added in closed reaction unit, hydrogen chloride gas is passed through under the conditions of 30~25 DEG C to be reacted, reaction is finished, and branch vibration layer, obtains the butylene of 1 chlorine of product, 3 methyl 2.The present invention, as raw material, without using organic solvent and catalyst in preparation process, simplifies aftertreatment technology, reduces environmental pollution, improve production efficiency and security using the alcohol of 3 methyl, 2 butylene 1 and with hydrogen chloride.

Description

A kind of preparation method of 1,3,2-CMB
Technical field
The present invention relates to chemical field, and in particular to a kind of preparation method of 1,3,2-CMB.
Background technology
1,3,2-CMB (1,3,2-CMB) is a kind of important intermediate, and it is used for synthetic pesticide, beast Medicine, spices, food additives and medicine, it prepares pesticide intermediate acetic acid isopentenyl ester with anhydrous sodium acetate reaction, is sent out with ketone Raw dehydrochlorination reaction obtains methyl heptenone.
It by isoprene and hydrogen chloride or hydrochloric acid is main that existing literature and patent report 1,3,2-CMB, which are, Raw material, using dichloromethane as solvent, catalyst reaction is made with stannous chloride, triethylamine hydrochloride or acetic acid and obtains the chloro- 3- of 1- Methyl-2-butene.The preparation method needs to use raw material isoprene and methylene chloride, because both chemical substances are boiled Point is low, and production and transport process hazard is big, and solvent recovery loss is big, the shortcomings of easily causing environmental pollution.
The content of the invention
The invention provides a kind of preparation method of 1,3,2-CMB, without solvent and catalyst, simplify Production technology, reduce environmental pollution, improve production efficiency and security.
In order to solve the above problems, the technical solution adopted in the present invention is a kind of such, chloro- 3- methyl -2- fourths of 1- The preparation method of alkene, comprises the following steps, and 3-M2BOL is added in closed reaction unit, -30~25 It is passed through hydrogen chloride gas under the conditions of DEG C to be reacted, reaction is finished, and branch vibration layer, obtains product 1,3,2-CMB.
Reaction principle is:
Described 3-M2BOL and the amount ratio of the material of hydrogen chloride are 1:1~1.5, preferably 1:1.25.
Preferably, hydrogen chloride gas is passed through under the conditions of -10~-5 DEG C to be reacted, and control reaction temperature in course of reaction Spend for -10~-5 DEG C.
Beneficial effect:The present invention, as raw material, need not make using 3-M2BOL and with hydrogen chloride in preparation process With organic solvent and catalyst, aftertreatment technology is simplified, reduces environmental pollution, improves production efficiency and security.
