PROCESS FOR PRODUCING FLUORINATED (METH)ACRYLIC ESTER

A mixture of fluoroalkyl iodides of the formula C2F5(CF2CF2)nI ( n is an integer of ≥0) wherein the sum of such fluoroalkyl iodides of n=3 and n=4 contained is ≥85 mol% is provided. This mixture is subjected to an ethylene addition step and an esterification step, and C2F5(CF2CF2)nCH=CH2 and C2F5(CF2CF2)nCH2CH2OH are removed. Thus, there can be obtained a mixture of fluorine-containing (meth)acrylic esters of the formula C2F5(CF2CF2)nCH2CH2OCOCR1=CH2 (wherein R1 represents a hydrogen atom or a methyl group, and n is an integer of ≥0) wherein the content of impurities (namely, olefins of the formula C2F5(CF2CF2)nCH=CH2 and alcohols of the formula C2F5(CF2CF2)nCH2CH2OH) is low.

PROCESS FOR PRODUCING FLUORINATED ACRYLIC ESTER

A mixture of fluorine-containing acrylic esters represented by CF3(CF2)nCH2CH2OCOCR1=CH2 wherein R1 is a hydrogen atom, a methyl group or a halogen atom and "n" is an integer of at least zero is subjected to distillation under such conditions that the esters are not polymerized, so as to give a mixture of the esters with a less content of impurities (that is, olefins represented by CF3(CF2)nCH=CH2 and alcohols represented by CF3(CF2)nCH2CH2OH) at a high yield.

PROCESS FOR PRODUCING FLUORINATED ACRYLIC ESTER

A mixture of fluoroalkyl alcohols represented by C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OH wherein "n" is an integer equal to or more than 0 wherein the sum of the fluoroalkyl alcohols of n=3 and n=4 contained is 85 mol% or more is prepared and reacted with an acrylic acid compound followed by removing unreacted C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OH, to give a mixture of fluorine-containing acrylic esters wherein the content of impurities (that is, olefins represented by C 2 F 5 (CF 2 CF 2 ) n CH=CH 2 and the alcohols represented by C 2 F 5 (CF 2 CF 2 ) n CH 2 CH 2 OH) is low.
