A kind of method for continuously preparing isopentenol

Abstract

The invention discloses a method for continuously preparing isopentenol. The method is as follows: using 3-methyl-3-butene-1-alcohol as a raw material, dissolving a catalyst in the raw material, and adding a solvent according to the proportion , under a certain pressure and temperature, use a plunger pump to pump the raw materials into the reaction tube for reaction, collect the reaction solution after cooling, and rectify to obtain pure prenol, the product purity is greater than 99%. The method of the invention is prepared in a continuous manner, and the operation is simple and convenient, and the reaction is carried out in a non-hydrogen-facing state. The catalyst used does not need to be prepared in advance and does not use noble metals such as palladium, cerium, and tellurium, and the production cost is low.

Description

technical field

[0001] The invention provides a method for continuously preparing prenol, which relates to the field of fine chemical product production. Background technique

[0002] 3-Methyl-2-buten-1-ol, also known as prenol, is an important intermediate in organic synthesis and has a wide range of uses in the fields of pesticides and synthetic fragrances. With the continuous deepening of the process, its application scope will become more and more extensive, and the demand will also increase greatly. Therefore, the research on the synthesis technology of prenol is of great significance.

[0003] The traditional method for producing isoprenol is the isoprene method, which uses isoprene as a raw material and is prepared through multiple steps such as oxidation, esterification, and saponification. The process route is long, the product selectivity is low, and it is environmentally friendly. serious pollution.

[0004] In recent years, isobutene and formaldehyde are used a...
