| Overview | Trifluoroacetamide is an important organic chemical raw material, mainly used to synthesize trifluoroacetonitrile and 2-trifluoromethyl-4-ethoxycarbonyl-1, 3-thiazole and other organic fluorine compounds, can also be used to prepare pesticides, medicines, and industrial chemicals. |
| preparation | ethyl trifluoroacetate is put into an acylation kettle with a pump, ammonia gas is introduced under stirring, and the reaction of ammonia gas is normal pressure, temperature 30 ℃, and reaction for 8 hours. The intermediate trifluoroacetamide is obtained by concentration, crystallization and centrifugation. |
| application | trifluoroacetamide can be used to prepare N,O-bis-trimethylsilyl trifluoroacetamide. N,O-bis-trimethylsilyl trifluoroacetamide is an important pharmaceutical intermediate. It is mainly used as a neutral silanization reagent in the silanization protection of amino groups, amino acids, phenols, carboxylic acids and enols. As a mild neutral silanization reagent, it not only has high reaction activity and good selectivity, but also has the advantages of high reaction yield and simple post-treatment. |
| use | organic synthesis. Synthesis of primary amines from halides or methanesulfonic acid compounds. |
