Abstract
Fluorination processes using hydrogen fluoride-containing fluorinating agents that are safely and easily handled, transported, and stored and that also exhibit good reactivity are provided. More particularly, the invention provides processes for producing fluorinated products using fluorinating agents comprising hydrogen fluoride and a carrier that may be an acid salt or a water-soluble polymer.
Claims27
A process for producing a fluorinated product comprising the step of initiating a fluorination reaction by contacting a fluorinating agent comprising an effective amount of hydrogen fluoride and a carrier with at least one feed material selected from the group consisting of unsaturated hydrocarbons, saturated and olefinic halocarbons and hydrohalocarbons having at least one halogen atom other than fluorine, and mixtures thereof, to for a reaction product comprising a fluorinated product.
A process for producing a fluorinated product comprising the step of initiating a fluorination reaction by contacting a fluorinating agent, comprising from about 60 to about 90 weight percent hydrogen fluoride and from about 40 to about 10 weight percent sodium polyacrylate, with at least one feed material selected from the group consisting of unsaturated hydrocarbons, saturated and olefinic hydrohalocarbons and halocarbons having at least one halogen atom other than fluorine, and mixtures thereof having from 1 to 19 carbon atoms and carrying out the fluorination reaction initiated at a temperature from about 25.degree. C. to about 100.degree. C. and pressure of from about 50 to about 200 psig to form a reaction product comprising a fluorinated product.
A process for producing a fluorinated product comprising the step of initiating a fluorination reaction by contacting a fluorinating agent, comprising from about 55 to about 85 weight percent hydrogen fluoride and from about 45 to about 15 weight percent of an acid salt having a pKa of about 4 or less, with at least one feed material selected from the group consisting of unsaturated hydrocarbons, saturated and olefinic hydrohalocarbons and halocarbons having at least one halogen atom other than fluorine, and mixtures thereof having from 1 to 19 carbon atoms and carrying out the fluorination reaction initiated at a temperature from about 25.degree. C. to about 100.degree. C. and pressure of from about 50 to about 200 psig to form a reaction product comprising a fluorinated product.
