Usage

General Description

alpha,alpha,alpha-Trichlorotoluene, also known as 1,2,3-Trichlorotoluene, is a chemical compound that is commonly used as an intermediate in the production of pesticides, pharmaceuticals, and plastics. It is a colorless liquid with a strong, sweet odor, and is insoluble in water but soluble in organic solvents. Trichlorotoluene is considered to be a hazardous substance, as it is toxic to aquatic organisms and may cause long-term adverse effects in the environment. It is also a potential human carcinogen and can cause skin and eye irritation upon contact. Due to its hazardous properties, trichlorotoluene should be handled and disposed of with proper care and in accordance with regulations set by the Environmental Protection Agency.

CLEAN PROCESS FOR PREPARING CHLOROFORMYL-SUBSTITUTED BENZENE

Clean process for preparing a chloroformyl-substituted benzene by oxidation of a tail gas hydrogen chloride from a chlorination reaction and a chloroacylation reaction and recycling of the resulting oxidation product chlorine gas into the chlorination reaction. The present invention provides a clean process for preparing a polymer-grade chloroformyl-substituted benzene.

METHOD FOR THE PREPARATION OF TRICHLOROMETHYL-GROUP-SUBSTITUTED BENZENE

The present application relates to a method for photochlorination, and specifically to photochlorination by a photochemical reaction of an aromatic compound with gaseous chlorine so as to prepare a trichloromethyl-substituted benzene, and to a method using bis-(trichloromethyl)-benzene as the trichloromethyl-substituted benzene to prepare by further reaction bis-(chloroformyl)-benzene. Through the control of temperature, illuminance and consumption of gaseous chlorine, the method of this application can greatly improve the purity of trichloromethyl-substituted benzene and further prepare polymer-grade bis-(chloroformyl)-benzene with low cost. The present application also relates to a method for purifying trichloromethyl-substituted benzene, and specifically to a method for purifying trichloromethyl-substituted benzene via molecular distillation. The present application further relates to a photochlorination reactor for use in photochlorination reactions (such as those of the present application).
