Description

  1. Product Overview

氯苯(又称一氯苯、氯代苯、苯基氯)为无色透明、易挥发的液体,具有类似杏仁的气味。化学性质较稳定,氯原子与苯环共轭,不易水解。

Chlorobenzene (also monochlorobenzene, benzene chloride, phenyl chloride) is a clear, colorless, volatile liquid with a characteristic almond-like odor. It is relatively stable; the chlorine atom is conjugated with the benzene ring and not readily hydrolyzed.

本品是重要的芳香族有机合成中间体,亦曾作为溶剂使用(因环境与健康顾虑,溶剂用途已趋减少)。广泛用于染料、颜料、农药与橡胶化学品中间体,以及有机硅生产等。

An important aromatic organic-synthesis intermediate, also formerly used as a solvent (its solvent use has declined due to environmental and health concerns). Widely used for dyes, pigments, pesticide and rubber-chemical intermediates, and in silicone production.
