Process method for preparing 3-acetyl-1-propanol

Abstract

The invention belongs to the technical field of organic synthesis, and particularly relates to a process method for preparing 3-acetyl-1-propanol, which comprises a tank body, a reaction tube and a condensation tube. A cavity is formed in the tank body. A containing tank is arranged at the bottom of the tank body in the cavity. A baffle is arranged at the position, above the containing tank, in the tank body. An air inlet guide pipe is mounted in the baffle. The reaction tube is arranged at the position, above the baffle, in the tank body. The upper end surface of the reaction tube is connected with the condensation tube. The problems in the prior art that the cost of raw materials for preparing 3-acetyl-1-propanol is relatively high, the reaction efficiency is relatively low due to smallcontact area of reactants and a catalyst in the reaction process, and the purity of the 3-acetyl-1-propanol obtained by the reaction is relatively low are solved. The method realizes low-cost and high-efficiency preparation of 3-acetyl-1-propanol, and unreacted raw materials can be directly and effectively collected, so the production cost is reduced, and the utilization rate of the raw materialsis improved.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, in particular to a process for preparing 3-acetylpropanol. Background technique [0002] 3-acetylpropanol is a colorless transparent liquid, boiling point 208°C (97.325kPa), 144-145°C (13.3kPa), relative density 1.0071 (20 / 4°C), refractive index 1.4390, miscible with water, soluble in ethanol And diethyl ether, volatilize in steam, and play a role in cyclization when distilled under atmospheric pressure. It is a pharmaceutical intermediate, mainly used in the antimalarial drug chloroquine phosphate, and can also be used in the production of vitamin B1, etc. [0003] In the prior art, the raw material cost of preparing 3-acetylpropanol is relatively high, and the contact area between the reactant and the catalyst is relatively small during the reaction, so that the efficiency of the reaction is low and the purity of the prepared 3-acetylpropanol obtained by the reaction is relatively low...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies in the prior art, solve the problem that the raw material cost of preparing 3-acetylpropanol in the prior art is relatively high, and the contact area of ​​the reactant and the catalyst in the reaction process is relatively small so that the efficiency of the reaction is low and the prepared 3-acetylpropanol obtained by the reaction is relatively low. The purity of acetylpropanol is relatively low, and the present invention proposes a process for preparing 3-acetylpropanol
