Raw material consumption quota: p-chlorobenzenesulfonic acid (92%) 1230kg/t, chlorosulfonic acid (95%) 2100kg/t, phenol (98%) 310kg/t, sodium hydroxide (95%) 157kg/t, chlorine ( 99.5%) 250kg/t, ferric chloride (99%) 1.8kg/t.
2.Using p-chlorobenzene sulfonic acid and chlorosulfonic acid as raw materials, the following steps are used to synthesize miticide.
3.Use p-chlorophenol and p-chlorobenzene sulfonyl chloride as raw materials to synthesize miticide under alkaline conditions.
Purpose
Non-systemic acaricide. Pesticide analysis standards. This product was first sold by the Swiss company Geigy as a mothproofing agent for woolen fabrics. Dicarbicide has good control effect on mite eggs and young mites, and is used to control various mites on cotton and fruit trees.
It has high activity against many plant-eating mites and eggs, with obvious residual ovicidal activity and slight insecticidal activity. It is used for various mites on cotton and fruit trees, and is generally harmless. It can also be used as a mothproofing agent for wool textiles.
