5000 tons/year mesylate project
1.概述
Methylsulfonic acid (MSA) is an important intermediate in organic synthesis and medicine. It is often used in organic synthesis as solvent, alkylation and lipidation reagent.MSA is also an ideal leveler and brightener。In recent years, the application in the electroplating industry is more and more extensive, and is gradually replacing the traditional fluoroborate and fluorosilicic acid plating solution, so MSA is a chemical product with a very promising development。
2.Market demand and forecast
As a strong organic acid, MSA can be used as a solvent, as well as a catalyst for alkylation, esterification and electrode reactions。With the wide range of applications, its production capacity and output are also growing rapidly。
At present, the total global MSA production capacity is 500,000 tons, of which the domestic production capacity is about 100,000 tons。While the domestic market demand needs about 150,000 tons, MSA market prospects are very good。
3.Production scheme
3.1 Production process overview
At present, the main production processes of MSA at home and abroad are synthesis and electrolysis, and the main synthesis methods are methyl sulfonyl chloride hydrolysis and methyl mercaptan oxidation。
3.2. Selection of process scheme
This project uses nitric acid as an oxidizing agent to oxidize methyl mercaptan to produce mesylate. The production process of this project is the proprietary technology of our institute。
