Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | (4-chloro-2-Methylphenoxy)acetic acid | HCID 7204 | — |
| Reactant | Sodium Hydroxide | HCID 14798 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | MCPA-sodium | HCID 2724048 | 99.7% |
Reaction Steps
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%.
