Yield:-
Reaction Conditions:
with sodium hydroxide in water at 50; for 0.2 h;Product distribution / selectivity;
Steps:
3; 4
The reaction solution obtained from Example 2 was neutralized by adding 30% strength aqueous sodium hydroxide dropwise at 50° C. over a period of 0.5 h. The yield of sodium methallylsulfonate in the reaction mixture is 95.2% based on the sulfur trioxide-DMF complex. 330 g of DMF (10%) were lost as a result of hydrolysis.; Example 4 InventiveThe reaction mixture obtained from Example 2 was admixed at 50° C. with 1.6 kg of water. The mixture was subsequently neutralized at 50° C. by means of 30% strength aqueous sodium hydroxide. The yield of sodium methallylsulfonate in the reaction mixture was likewise 95.2% based on the sulfur trioxide-DMF complex. The loss of DMF as a result of hydrolysis was less than 0.3%.
