PROCESS OF HANDLING METHANESULPHONIC ACID USING STAINLESS STEEL

A method for handling aqueous solutions of methanesulfonic acid (MSA) having a concentration from 50 to 99% by weight of MSA and a total chlorine content of less than 50 mg/kg in apparatuses in which the aqueous MSA solution is in contact with steel surfaces. The steel comprises austenitic steels ha...

Zusammenfassung:	A method for handling aqueous solutions of methanesulfonic acid (MSA) having a concentration from 50 to 99% by weight of MSA and a total chlorine content of less than 50 mg/kg in apparatuses in which the aqueous MSA solution is in contact with steel surfaces. The steel comprises austenitic steels having a chromium content of from 15 to 22% by weight and a nickel content of from 9 to 15% by weight.
