Abstract

NEW MATERIAL:A diphenyl ether dericative of the formula (X=halogen or nitro).
EXAMPLE: 2-Chloro-4-trifluoromethylphenyl-3,4-dinitrophenyl ether.
USE: The herbicide has higher herbicidal activity and selectivity than 2,4-dichlorophenyl-4-nitrophenyl ether and 2,4,6-trichlorophenyl-4-nitrophenyl ether.
PROCESS: For example, m-nitrophenol, K2CO3 and sulphoran are mixed. Then 3,4- dichloro-benztrifluoride is added to this mixture and made to react at 170W180°C for 6 hr to give 2-chloro-4-trifluoromethylphenyl-3-nitrophenyl ether, which is dissolved in acetic adhydride. To this solution, a mixed acid is added dropwise, maintaining the temp. between 5W10°C, to give a diphenyl ether compound of the formula.
