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.

Purification of fluorinated alcohols

A process for reducing the level of perfluoroalkanoic acids, perfluoroalkanoic esters, and perfluoroalkyliodides in fluorinated alcohols comprising heating a fluorinated alcohol, or mixtures thereof, containing said acids, esters, or iodides to a temperature of at least 175° C. in the presence of water and a base additive is disclosed.
