摘要： A process for producing 1,1,1-trifluoroacetone includes the step of conducting a hydrogenolysis of a halogenated trifluoroacetone, which is represented by the general formula (1), by a hydrogen gas in the presence of a catalyst containing a transition metal, where X represents a chlorine, bromine or iodine, and n represents an integer from 1 to 3. It is possible to obtain 1,1,1-trifluoroacetone with a high yield by using the special catalyst.

摘要： Aminoethanol is reacted with a fluoroalkylsulfonic anhydride to obtain a fluoroalkylsulfonylaminoethanol (first step: sulfonylamidation step). The fluoroalkylsulfonylaminoethanol is esterified with an α-substituted acrylate derivative to obtain a desired fluoroalkylsulfonylaminoethyl α-substituted-acrylate (second step: esterification step). Thus, the desired fluoroalkylsulfonylaminoethyl α-substituted-acrylate having a higher purity can be produced in higher yield with higher operating efficiency than in conventional techniques.

摘要： According to the present invention, an α-substituted acrylic ester monomer for a fluorinated resist is produced by direct addition of an α-substituted acrylic acid to a fluorinated alkene in the presence of a specific acid catalyst having a sulfonyl group. By the use of such a specific acid catalyst, it is possible to achieve industrial-scale production of the α-substituted acrylic ester monomer for the fluorinated resist by carrying out the target addition reaction of the fluorinated alkene and the α-substituted acrylic acid efficiently during the occurrence of side reactions such as isomerization of the alkene, generation of a diol and excessive addition of the α-substituted acrylic acid.
