Abstract

NEW MATERIAL:The diphenyl ether compound of formulaI(R1 is H, lower alkyl, lower alkenyl or lower alkynyl; R2 is H or lower alkyl; R3 is loer alkyl).
USE: Herbicide having excellent herbicidal activity and high selectivity. It has excellent activity against especially annual and perennial weeds in paddy rice field, and large crab-grass, green foxtial, cockspur-grass, etc. in polowed land, and has low phytotoxicity to crops.
PROCESS: The compound of formulaIis prepared by reacting a disphenyl ether compound of formula II with nitric acid or a mixed acid composed of nitric acid and sulfuric acid, in a solvent such as benzene, toluene, etc., at -50W+20°C for 10minW5hr. The concentration of the nitric acid is 50W100%.
