Method for preparing perfluoroalkyl ethanol

The invention discloses a method for preparing perfluoroalkyl ethanol. The method comprises the following steps: enabling perfluoroalkyl ethyl iodide, a mixed solvent and water to react, and separating and purifying the obtained mixture containing perfluoroalkyl ethanol, by-product olefins, solvent salt and water, thereby obtaining the perfluoroalkyl ethanol product, wherein the separation and purification comprise the following steps: (1) adding a mixture containing perfluoroalkyl ethanol, by-product olefins, solvent salt and water into a rectifying tower for performing reduced pressure distillation, controlling the vacuum degree to be -0.91 to -0.96MPa so as to obtain distillate containing perfluoroalkyl ethanol, by-product olefins and water and bottom liquid, performing strong base treatment on the bottom liquid, and filtering to obtain the recycled mixed solvent; and (2) performing azeotropic distillation on the distillate, thereby obtaining the mixed solution of the by-product olefins and water and the product perfluoroalkyl ethanol. The method disclosed by the invention has the advantages of simplicity in process, greening, environment friendliness, convenience, high efficiency and low cost.

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.
