Research on the Corrosion of Metal Materials in Industrial Production Equipment of Methyl Propionate by Methanesulfonic Acid
In the production process of methyl propionate,a small amount of methanesulfonic acid is generally used to adjust the system acid value.As the concentration of methanesulfonic acid increases,it will cause corrosion to the equipment.Through experimental research on the corrosion of 316L stainless steel,Hastelloy C-276,SS2205 stainless steel,SS304 stainless steel,and TA2 titanium materials by a methyl propionate solution containing methanesulfonic acid and methanol under pressure of 1.0 MPa and temperature of 100℃,the material of the equipment used for industrial production of methyl propionate is evaluated and optimized.The experimental results indicate that SS2205 and C-276 are the preferred materials for industrial production equipment of methyl propionate.Considering economic factors,SS2205 is the more optimal choice
