1,1,1 -trifluoro-2- ethane

A reagent which is primarily of interest as a means of converting alcohols into fluorides has been used to dehydrate C-11 alcohols in high yields. 1 la-Alcohols dehydrate rapidly with 2-chloro-l-diethylamino-l,l,2-trifluoro-ethane reagent at low temperature, while 11 j5-alcohols require refluxing methylene chloride. Traces of fluoro compounds have been detected in the products.

The photolysis of trifluoroacetone with light of wavelength 3130 A. has been studied by Sieger and Calvert.48 The products of decomposition were shown to be carbon monoxide, methane, ethane, 1,1,1-trifluoro-ethane, and hexafluoroethane. There was no indication of the presence of carbon tetrafluoride or methyl fluoride. The quantum yield of all products was low at low temperature and it is assumed that the excited molecule of trifluoroacetone has an appreciable lifetime and may be deactivated by collision before decomposition can occur. This contention is supported by the decrease in the quantum yields observed when foreign gases such as carbon dioxide are added, and by the fall in quantum yields with increase in trifluoroacetone concentration.

Organic solvents used must be compatible with the enzymatic activity, not take place in the reaction, be good solvent of the substrates, have a low cost, and be the more harmless possible. The solvents commonly used in the literature are aliphatic alkanes, or similar compounds of low polarity. Aliphatic ethers that were used in this work, show less hydrophoblcity than alkanes, and thus allow introduction of water for hydrolysis reactions. For interesterification experiments, trichloro-trifluoro-ethane was used, as water is not a substrate for the reaction (Fig. 5,). 

A single segment mycelium reactor was used with trichloro-trifluoro-ethane as solvent (Fig, 5,). For a concentration of 25% (V/V) of triglycerides, full interesterification was obtained within 1 hour of residence time. The productivity of the system can be estimated to 1.5 kg of interesterified product per hour and per kg of dry mycelium.

Non-aqueous polymerization is frequently carried out in an inert fluorinated solvent such as 1,1,2-trichloro 1,2,2-trifluoro ethane, perfluoro methyl cyclohexane, perfluoro dimethyl cyclobutane, perfluoro octane or perfluoro benzene. As the free radical initiator, a perfluorocarboxylic acid peroxide (RfC00)2, an azo bis type compound such as azobisisobutylo-nitrile, or a fluorine radical initiator such as N2F2 may be used.
