Abstract

The invention provides an analgin production technology control system based on computer control. The analgin production process control system is characterized in that the system composition comprises a PLC control cabinet 01, a PLC control cabinet 02, an AT methylation hydrolysis substation, an FAA methylation substation, an MAA neutralization substation, a condensation-finished product substation, an AA nitrosation control substation, an FAA acylation control substation, an MAA hydrolysis control substation, an analgin master station, an optical fiber switch and field instruments. The analgin production technology control system can make the traditional technical process intensive and visual, and greatly improves the production efficiency and management level while reducing labor intensity of staff and management cost.

Description

technical field [0001] The invention relates to the fields of medicine, chemical industry and industrial computer control, in particular to a computer-controlled Analgin production system. Background technique [0002] Analgin, also known as Roval essence, 1-phenyl-2,3-dimethyl-4-methylamino-5-pyrazolone-N-methylsulfonate monohydrate. The relative molecular mass is 351.36. White to light yellow crystal or crystalline powder. Hardly soluble in ether, soluble in ethanol, easily soluble in water, the aqueous solution is easy to turn yellow. [0003] [0004] At present, the route of industrial production of Analgin is to use pyrazolone as a starting material, through methylation, hydrolysis and alkalization to obtain antipyrine (AT) oil, and AT oil is then nitrosated, reduced, hydrolyzed and neutralized to obtain 4- Aminoantipyrine (AA) oil, AA oil is then subjected to acylation, crystallization, and centrifugation to obtain 4-formylaminoantipyrine (FAA), and then FAA is ...
