Appearance：

Trichlorofluoromethane appears as a clear light colored liquid. Nearly odorless. Denser than water. Poses low acute health hazard to humans. Primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways.

Trichlorofluoromethane Use and Manufacturing

Methods of Manufacturing

The liquid phase contact method of carbon tetrachloride and hydrogen fluoride is mainly used, and the methane fluorination method is used for production. The liquid phase contact method uses antimony pentachloride as a catalyst, and carbon tetrachloride reacts with anhydrous hydrogen fluoride to form monofluorotrichloromethane and difluorodichloromethane, and by-product hydrochloric acid. The reaction product is free of hydrogen chloride, washed, dehydrated, degassed, and fractionated to obtain a finished product. Figure 76 is a process for preparing chloroform by carbon tetrachloride. The methane fluorochlorination method consists of methane, chlorine and hydrogen fluoride at 370-470°C and a pressure of 0.39-0.59 MPa for 4-10 seconds to obtain monofluorotrichloromethane and difluorodichloromethane. The mixture of monofluorotrichloromethane and difluorodichloromethane (the two components each account for 50%), the yield in terms of methane is more than 99%, and the purity of the separated products is more than 99.95%.
