Problems solved by technology

[0005] The product aspartic acid methyl ester produced by this device is an intermediate in the production of asparagine, and its quality directly affects the yield and quality of aspartic acid methyl ester. The traditional esterification method of aspartic acid methyl ester is aspartic acid In the acid methanol solution, feed excessive hydrogen chloride gas, and complete esterification at a low temperature. This production method has the following defects: 1. hydrogen chloride gas is volatile, and the production environment is poor; Reaction into polymer; 3. High cost and high energy consumption; 4. Low yield; 5. Product quality cannot be improved

Embodiment Construction

[0018] Further illustrate the specific content of using this novel device to produce methyl aspartate best embodiment below in conjunction with accompanying drawing:

[0019] 1. Add chemically pure sulfuric acid with a concentration of 30% into the first stirring tank 1 through the first raw material inlet 6 arranged on the first stirring tank, and then add pharmaceutical grade aspartic acid powder through the same inlet 6, the two raw materials The weight ratio is sulfuric acid with a concentration of 30%: aspartic acid powder = 5:5, after stirring and reacting for 2-2.5 hours at room temperature, a solid-liquid mixture of aspartic acid sulfate is obtained, and aspartic acid sulfate The solid-liquid mixture is sent into the filter 2 to filter out the liquid part through the first slurry pump and the pipeline 7 arranged between the first stirring tank 1 and the filter 2, and the liquid part is discharged through the filtrate outlet 8 arranged on the filter 2 , The obtained sol...

Description

[0001] Technical field: [0002] The invention belongs to the field of amino acid production, in particular to a mechanical device for producing methyl aspartate. [0003] Background technique: [0004] Asparagine is a kind of medicine, its molecular formula is C4H8N2O3, its molecular weight is 132.12, and its melting point is 234-235°. Sexual ulcer and gastric dysfunction, intravenous injection can cause blood pressure to drop, peripheral blood vessels to expand, cardiac contractility to increase, heart rate to slow down and urine output to increase. When pyloric ligation rats are taken orally, it can prevent gastric mucosal damage caused by oral administration of acetylsalicylic acid Injury, animal experiments show that it has significant antitussive effect and a certain anti-asthmatic effect, and can also be used for microbial cultivation, sewage treatment of acrylonitrile, etc. [0005] The product aspartic acid methyl ester produced by this device is an intermediate in th...
