Abstract

The invention relates to a method for synthesizing betaine, which is characterized in that the method uses trimethylamine and chloroacetic magnesium at the molar ratio of 1.02-1.03:1 for amination and synthesis; the reaction temperature of synthesis is controlled between 40 and 60 DEGC; the optimum reaction temperature is controlled between 53 and 55 DEG C; a pH value is controlled to be between 8 and 9; synthesis time is between 2.5 and 5 hours; continuous feeding and continuous discharging are adopted; and the feeding and discharging of reaction are regulated and controlled by use of a pH meter. The method has the advantages of eliminating frequent operation for feeding, synthesis and discharging during batch production, as well as unsafe factors possibly caused by the frequent operation, increasing production yield, treating and recycling water after the concentration of betaine solution and reducing the waste of freshwater resources.

Description

technical field [0001] The invention relates to a method for synthesizing betaine. technical background [0002] Betaine is a widely used additive at present. It is used in feed, food, cosmetics, medicine, etc. It is a betaine synthesized by using sodium chloroacetate and trimethylamine as raw materials. The process flow chart is shown in figure 1 . This process has the following disadvantages: 1) Intermittent production, frequent operation of feeding, synthesis and discharging in the production process, low production output, low equipment utilization rate, and long time-consuming safety treatment process, in addition, frequent operations may cause unsafe factors ; 2) The sodium chloride that reaction solution is concentrated and separated is difficult to carry out industrial utilization, and the production process water is not fully utilized, and the production cost is high, and the equipment is discharged, and the feed is vented to cause environmental pollution. Conten...
