Study on the Synthsis of 1,1,5-Tri-Hydrofluorpentyl Methylacrylate

In this paper, the new methods for the prep.of 1,1,5-Tri-hydrofluoropentyl methylacrylate are described. Several kinds of dehydrants are first used and the best one for the prep, is sifted from them. The decrease of the reaction time by using the dehydrant brings about a marked improvement for the prep. The current yield(92%)is about 4 times the yield published recently in literature(67%). According to experimental result, main factors which affect the reaction are discussed in detail. Moreover the optimum conditions of the reaction are summarized. The sability tests have been made under the conditions and the results are rather satisfactory.
