Glycine Continuous Production Technology Research

The glycine, the structure is the simplest of the α -Amino acid . Its use is very extensive, Used in the agriculture chemical, medicine, fodder, food, and making and fetch other amino acid mainly , Formate surface-active agent, etc. There are many kinds of produce the glycine, There is method of produce the glycine by ammoniation of chloroacetic acid and produce the glycine by Strecker. At home, because of the raw materials reasons, adopt method of produce the glycine by ammoniation of chloroacetic acid..Chemical engineering group incorporated company of Xin' an of Zhe Jiang, produce the glycine by ammoniation of chloroacetic acid. It is more worthier than theory and much lower that the accepting rate exists in process of production, the quantity of the urotropine is heavy, Weak point such as being difficult of sewage disposal, In order to place oneself in ?the very latest in the fierce sour market competition of the glycine, Need more advanced technology, Improve the output, lower costs .Pass the lab scale, production technology in succession of glycine is feasible. And has exactly used technology in succession . There are conditions in a lot of side reactions , have the ability to control, Accept the rate of the glycine can be more improvement. On the basis of lab scale, proceed the mold tries of ammoniation of chloroacetic acid on consecution , Through a lot of modification and adjustment, handing in the test and analysing , get a lot of data and craft parameter that can be controlled, Have obtained more than 95% of accepting rate of reacting of the glycine, it is unit consumption 38kg/t of urotropine, Total production cost constant of the glycine each ton drops by 1213 yuan at present.On the foundation that the model tries, Design per year 150 tons of the glycine produce the reactor in succession, At the same time , have designed the technological process and establish the craft parameter, Have tried to find out the essential supplementary equipment in some technological process, In order to have the design of the ten thousand -ton inning charge of type reactor, sureness of the technological process , lay the sturdy theoretical foundation and reliable experimental data.
