The first reaction kettle 1 is communicated with the second reaction kettle 2 through the electromagnetic valve 11 and the liquid delivery pipeline 12. The first reaction kettle 1 is used as a primary reaction tank. When the alkyl liquid is poured into the first reaction kettle 1 through the alkyl liquid three-way pipe 10, the ammonia water solution is delivered to the liquid storage tank 5 through the ammonia water solution delivery pipeline 51. The liquid storage tank 5 stores the ammonia water solution and delivers it to the liquid storage head 52 through the liquid gravity.

Since the dripping head 53 is attached along the inner wall of the reactor, it is ensured that the ammonia aqueous solution is in a liquid flowing state and is mixed with the alkyl liquid. Start the stirrer 9, the stirrer 9 drives the stirring shaft 91 to rotate, and the blade 92 stirs and mixes the mixed liquid. When the alkyl liquid and ammonia aqueous solution are initially reacted to produce a mixed liquid, further processing is required. The mixed liquid can be transported from the liquid pipeline 12 to the second reactor 2 by pump pressure.
