Chlorotrifluoroethylene - Preparation Method

Open Data Verified Data

with 1,1,2-fluorine -1,2,2-ethyl chloride (Freon -113) as raw material, in methanol dispersion medium, and zinc powder reaction dechlorination, the product was purified by fractional distillation. When pressurized to 1. 17MPA, the reaction temperature can be increased, the reaction rate and yield can be increased, and the amount of methanol used can be reduced.

Chlorotrifluoroethylene - Safety

Open Data Verified Data

highly toxic! In the air easily oxidized and decomposed into phosgene. Rat oral LD50 268mg/kg,24 hours inhalation of LC 1000 x 10-6. On the human cardiovascular, nervous system has obvious effect, poisoning symptoms of Head Pain, Nausea, Vomit, severe damage to the kidney, and can appear jaundice. Symptoms of poisoning should be treated promptly. The maximum allowable concentration in air is 2 × 10-6. Good ventilation should be strictly maintained at the operation site, and the operator should wear protective equipment.
with a clean, dry pressure (0. 9806MPa) stainless steel cylinder, the need for low temperature (- 20 ~- 30 ℃) storage and transportation, long-term storage should add polymerization inhibitor. According to the provisions of toxic hazardous chemicals storage and transportation.

use	used to prepare polytrifluoroethylene chloride resin and fluororubber trifluoroethylene is polymerized into polytrifluoroethylene. it has excellent electrical properties, heat resistance and chemical resistance are inferior to polytetrafluoroethylene, but it is easy to process and can be made into plastic, film, coating and other products. the working temperature is -196~199 ℃. It is also a raw material for fluoroplastics, fluororubber, refrigerants, fluorochlorine lubricants, and halothane anesthetics. Used to replace hydroxyl groups in steroids and carbohydrates with fluorine as preservatives.
production method	Germany first produced chlorotrifluoroethylene in 1934, and the United States realized industrial production in 1949. The method commonly used in industry is dechlorination of trifluorotrichloroethane. Generally, zinc powder is used as dechlorination agent, methanol is used as solvent, the reaction temperature is 50-150 ℃, the reaction pressure is 2.08MPa, and the reaction time is 3-4s. The methanol suspension containing zinc powder is sent to the reactor together with trifluorotrichloroethane, and the generated zinc chloride is separated from the reactants. After the reaction products are sent to the primary distillation tower and the rectification tower, pure trifluorochloroethylene is obtained. Raw material consumption quota: 1830kg/t trifluorotrichloroethane, 1080kg/t methanol (>95%) and 840kg/t zinc powder (>95%).
