Procedure

6.6 parts (0.1 mol) of powdered potassium hydroxide (85%) are introduced into a melt of 20 parts (0.1 mol) of MCPA (93.3%) with stirring and the mixture is kept at 130° C. for 30 minutes. After solidification, 26 parts of MCPA-potassium having an MCPA content of 71.8% are obtained, which corresponds to a yield of 100%. M.p.: 203° C.
