Preparation and processing technology of organic amide

Abstract

The invention provides a preparation and processing technology of an organic amide. The preparation and processing technology comprises the following steps: a solvent is mixed with the organic amine and a catalyst in a feeding pipe to obtain a first mixture; the obtained first mixture enters a first heat dissipation pipe through a second emptying valve for heat dissipation; one part of the first mixture subjected to heat dissipation enters a static reaction tank through a first discharge valve, a fourth discharge valve and a liquid inlet pipe and is heated through the static reaction tank, the other part of the first mixture subjected to heat dissipation enters the second heat dissipation pipe through the first discharge valve and a second liquid conveying pipe for heat dissipation, and the first mixture subjected to heat dissipation again passes through the first discharge valve, and flows back to a first infusion tube to form circulation; a hydrogen peroxide solution is mixed with the first mixture to obtain a second mixture; and after filtering out the catalyst from the second mixture, carrying out organic distillation to obtain the organic amide. Through circulation of the mixture in a pipeline, local overheating of the mixed raw materials due to mutual reaction is prevented.

Description

technical field [0001] The present invention mainly relates to the technical field of synthesis of amides, in particular to a preparation and processing technology of organic amides. Background technique [0002] Organic amines are an important class of organic compounds, mainly used as multifunctional weak cationic surfactants, and widely used in soap base and surfactant bath products. [0003] According to the preparation method of an organic amine oxide provided by the patent literature with the application number CN201910161460.5, it can be known that the preparation method includes the following steps: (1) using organic amine as raw material, combining organic amine, solvent and phosphotungstic Add the multi-acid quaternary ammonium salt catalyst into the container and heat up (25-100°C); (2) add hydrogen peroxide solution dropwise for about 1.5 hours, and keep warm after the dropwise addition; (3) detect the reaction solution by gas chromatography, When the content of...

Problems solved by technology

[0004] The above-mentioned preparation and production process is simple, low energy consumption, and the catalyst can be reused, which can effectively reduce the production cost. However, in the process of producing organic amides in the traditional preparation method, a large amount of heat will be released during the reaction process, and the heat-conducting material is easy to react during the reaction. Cause local overheating, affect reaction efficiency, and lead to low yield of equipment
