100-44-7 – Introduction
Chlorobenzene is an organic compound with the chemical formula C7H7Cl. It is a colorless and transparent liquid with a special aromatic odor. Benzyl chloride is mainly used as a solvent and chemical intermediate, and is widely used in fields such as organic synthesis, coatings, dyes, insecticides, and polymers.
Benzyl chloride is widely used in industry. It is mainly used in the fields of pesticides, medicines, fragrances, dye additives, and synthetic additives. It is used to develop and produce benzaldehyde, butyl benzyl phthalate, aniline, phoxim, Benzylpenicillin, benzyl alcohol, phenylacetonitrile, phenylacetic acid and other products. Benzyl chloride is a kind of benzyl halide irritating compound. In pesticides, it can not only directly synthesize organophosphorus fungicides rice blast net and different rice blast net, but also can be used as an important raw material for many other intermediates, such as synthesis of phenylacetonitrile, Benzoyl chloride, m-phenoxybenzaldehyde, etc. In addition, benzyl chloride is widely used in medicine, spices, dye additives, synthetic resins, etc. Then the waste liquid or waste produced by the enterprise in the production process inevitably contains a large amount of benzyl chloride intermediate.
