Production method of N-ethyl iso penlyl amine and its device

Abstract

A process for preparing the N-ethyl isopentylamine includes such steps as proportionally mixing isopentanol with ethylamine, loading the liquid mixture along with carried catalyst and H2 into vaporizing chamber, pre-heating for vaporizing, catalytic ammonolyzing reaction in fixed-bed reactor, condensing the resultant, and rectifying.

Description

technical field [0001] The invention relates to a fixed-bed synthesis method of fatty amine, in particular to a production method of a chemical intermediate - N-ethylisoamylamine and a device used therein. Background technique [0002] N-ethylisoamylamine is an important organic chemical intermediate. There is no bibliographical report of synthesizing N-ethyl isoamylamine at present; According to the general route of preparing ethyl secondary amine, the N ethylation of isoamylamine can be adopted, and the ethylating reagent is diethyl sulfate, and reaction equation is as follows: [0003] [0004] The biggest shortcoming of this reaction is exactly that the ethylating reagent diethyl sulfate that adopts is too toxic, and the by-product monoethyl sulfate of reaction hardly has the value of continued utilization. Therefore, this reaction has its limitations in terms of operability and economy. Contents of the invention [0005] Aiming at the problems in the prior art, t...

AI Technical Summary

Problems solved by technology

[0004] The biggest disadvantage of this reaction is that the ethylating reagent diethyl sulfate used is too toxic, and the monoethyl sulfate produced by the reaction has almost no value for continued utilization.

Therefore, this reaction has its limitations in terms of operability and economy
