Method for synthesizing allylamine using transfer line reactor

Abstract

The invention discloses a preparing method of alkylamine through pipe reactor, which comprises the following steps: adopting allyl chloride as raw material; blending catalyst, solvent and ammonia phase evenly; pumping in the pipe reactor through metering pump according to the rate of materials; ammonifying to produce acrylamide, diallylamine and triallylamine; adding sodium hydroxide solution to remove amino to obtain the product; setting the normal pressure in the reactor system at 3.0Mpa under 40-80Deg C for 5-20min; rectifying the product; evaporating the solvent and surplus ammonia; gathering 52-55Deg C fraction as acrylamide; boiling to remove water; gathering 107-111Deg C fraction as diallylamine.

Description

technical field

[0001] The invention relates to a chemical synthesis method, in particular to a method for preparing allylamines using a pipeline reactor. Background technique

[0002] Allylamine (alias: 3-aminopropene), used in pharmaceutical intermediates, household chemicals, emulsion modifiers, organic synthesis and resin modifiers, silicon products, etc. It has been reported that polymers that can be polymerized with plasma to generate reverse osmosis wax are used in airtight manned spacecraft; they can also be used as corrosion inhibitors, catalysts and solvents.

[0003] Diallylamine (alias: two-2-propenylamine), is a widely used organic synthesis intermediate, organic synthesis raw material, ionic water purifier, polymer monomer, pharmaceutical intermediate and synthetic resin modified body.

[0004] Such substances have been reported in the literature, such as Duan Changqiang, Meng Zhuangfang, Zhang Tai, etc. The first volume of mod...
