Embodiment 1

[0043] Embodiment 1, the production method of N-ethylisoamylamine of the present invention, then carry out following steps successively:

[0044] 1), close stop valve 28, make stop valve 3, 4, 9, 18 all be in open state; Add isoamyl alcohol 88g (1mol) respectively in metering tank 8, ethylamine 90g (2mol), form mixed solution;

[0045] 2), the H in the high-pressure gas storage tank 1 2 After passing through the pipeline 19, it enters the pressure reducing valve 2 for decompression treatment. The pressure value set by the pressure reducing valve 2 is the working pressure in the following aminolysis reaction. A part of H from pressure reducing valve 2 2 Directly through line 20 to header 23, H 2 The flow rate is controlled by flow meter 5. Another part that comes out from decompression valve 2 enters metering tank 8 through pipeline 21, and this part H 2 The flow rate is controlled by flow meter 6; this part H 2 Push the mixed liquid in the metering tank 8 to flow to the c...

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...
