Reaction Steps
Into the experimental apparatus described in Example 1, 2 g HgSO4 and 10 g BBr3 are added. A solution of 93.7 g CF3CCl3, 162 g SO3 and 4 g H2SO4 are added in drops. The trifluoroacetylchloride leaving the reflux condenser is passed through a wash flask with H2SO4 and subsequently fed into a reaction vessel with ethanol. In the process, trifluoracetic acid ethylester is formed.
