A method of producing a mixture of fluorine-containing (meth)acrylate esters, the method including:

Method for producing mixture of fluoroalkyl iodide telomers and method for producing mixture of fluorine-containing (meth)acrylate esters

A mixture of fluoroalkyl iodide telomers represented by the formula: R(CFCF)I wherein Rrepresents a fluoroalkyl group whose number of carbon atoms is in the range of 1 to 10, with the polymerization degree n equal to or more than k that is an integer of 3 or more, is obtained by reacting a fluoroalkyl iodide with tetrafluoroethylene in a first reactor followed by fractionating a first reaction mixture which contains fluoroalkyl iodide telomers of low polymerization degree, as well as by reacting the telomer with n of (k&#x2212;1) separated from the first reaction mixture with tetrafluoroethylene in the second reactor.

Method for producing fluoroalkyl iodide telomer mixture and method for producing mixture fluorine-containing (meth) acrylate esters

Method for producing difluoromethane and 1,1,1,2-tetrafluoroethane

Process for preparing fluoroalcohol

A novel 5-fluorouridine derivative of the formula: ##STR1## wherein R.sup.1 is a C.sub.1 -C.sub.10 aliphatic carbonyl group, R.sup.2 is a fluorine atom or a C.sub.1 -C.sub.3 aliphatic carbonyloxy group, and x is a halogen atom such as a fluorine, chlorine, bromine and iodine atom, which is useful as an intermediate in the preparation of a 5-fluoro-2'-deoxyuridine derivative which is useful as an anticancer agent.
