Embodiment 1

[0047] Embodiment 1, the production method of N-ethylbutylamine of the present invention, then carry out following steps successively:

[0048] 1), close stop valve 28, make stop valve 3,4,9,18 be in open state; Add n-butanol 88g (1mol) respectively in metering tank 8, ethylamine 90g (2mol), form mixed solution;

[0049] 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 of H from pressure reducing valve 2 2 Enter the metering tank 8 through the pipeline 21, 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 collecting pipe ...

Abstract

The invention discloses a production method of N-ethyl butylamine, which includes three steps. Firstly, n-butanol and ethylamine are mixed in a metering tank to form mixed solution; secondly, the activated supported catalyst is put in a tubular reactor, part of the hydrogen in a high-pressure gasholder directly enters into an evaporation chamber, and another part drives the mixed solution in the metering tank together to enter into the evaporation chamber for preheating and vaporization and then enter the tubular reactor, and under the function of the supported catalyst, aminolysis reaction is carried out; thirdly, the product generated by the aminolysis reaction is condensed and rectified, so that N-ethyl butylamine is produced. The invention also provides a production device realizing the method. The N-ethyl butylamine produced by the device and method for the invention is characterized in low cost, high yield rate and environmental protection.
