PROCEDURE

实验过程

20 parts (0.1 mol) of 2-methyl-4-chlorophenoxyacetic acid (MCPA) (94.7%) are melted at 130° C. and reacted with 45 parts (0.1 mol, based on 100%) of 8.9% strength sodium hydroxide solution with simultaneous removal of methanol by distillation. After complete removal of methanol by distillation, 23.5 parts of MCPA-sodium of m.p. 227-230° C. are obtained, containing 80.8% MCPA, which corresponds to a yield of 99.7%.
