77568-66-2 - Introduction
Nature:
2,2, 2-trifluoroethane is a fluorinated alkane, which has good chemical stability and is not easy to burn. It has low surface tension and low viscosity, and has good solubility for many common solvents and compounds. In addition, 2,2, 2-trifluoroethane is less toxic and has less impact on the environment.
Use:
2,2, 2-Trifluoroethane is primarily used as a solvent and extractant. In chemical laboratories, it is often used to dissolve organic compounds and prepare solutions. In industry, it is also widely used in chemical synthesis, metal treatment and cleaning. In addition, 2,2, 2-trifluoroethane can also be used as a raw material for certain pharmaceuticals or fine chemical products.
Preparation Method:
There are many methods for preparing 2,2, 2-trifluoroethane, and common methods include hydrogenation reaction of fluoroalkanes, ammonium carbonate method and hydrogen trifluoride method. Among them, the hydrogen trifluoride method is the most commonly used method, which is prepared by reacting ethylene with hydrogen fluoride in the presence of a catalyst.
Safety Information:
2,2, 2-trifluoroethane has low toxicity, but it is still necessary to pay attention to safe use. It has a low boiling point, in high temperature and flame volatile formation of combustible gas, should be away from the fire and heat source to avoid the risk of fire or explosion. In case of contact with skin and eyes, rinse immediately with plenty of water and seek medical help. In addition, 2,2, 2-trifluoroethane has certain toxicity to aquatic organisms, and environmental protection measures should be paid attention to during use.
