Procedure

A melt of 20 parts (0.1 mol) of MCPA (94.7%) is reacted with 100 ml of 1 molar methanolic potassium hydroxide solution (0.1 mol) at 130° C. with removal of methanol by distillation. After complete removal of methanol by distillation, 25.1 parts of MCPA-potassium are obtained, containing 73.3% of MCPA of m.p. 200-205° C., which corresponds to a yield of 100%.
