Chemical reaction and application:
Trifluoroacetic acid ethyl ester is a special compound of organic synthesis. The reaction mainly lies on the ester's nucleophilic substitution effect and produces trifluorine acetylizes compound. The most important reaction is the ester condensation synthesis β - diketone, the amine trifluorine acylations, the ester and the phosphine derivative reaction, and the organic-metal react and synthesis into fluorizating alkone.
Transportation And operation:
Supply the Trifluoroacetic acid ethyl ester with inside lining polyethylene layer metal drum. When operate with trifluoroacetic acid methyl ester, avoid to touch the skin or absorb its vapor, and must wear the protective clothing. If any parts of body carelessly contact it, must immediately wash the part with massive water. The operational site must maintain good ventilation.
