Abstract
NEW MATERIAL:2,4-Dichloro-m-toluic acid of formulaI(Z is hydroxyl, halogen, lower alkoxy) and its derivative.
EXAMPLE: 2,4-Dichloro-m-toluic acid.
USE: Synthetic intermediate of other dichlorobenzoic acid derivatives used as agricultural chemicals, medicines, plasticizers, surfactants, flame retarders or other chemicals. Especially, synthetic intermediate of pyrazole dichlorobenzoic acid derivatives used as a herbicide.
PREPARATION: The liquid-phase autoxidation of a compound of formula II (R is lower alkyl, acetyl and functional groups derived from them) is conducted in a lower fatty acid solvent, when R is lower alkyl, in the presence of an oxidation catalyst and co-catalyst, using molecular oxygen to produce the compound of formulaIwhere Z is hydroxyl selectively in high yield.
