570157

Abstract:

A process for producing a fluoroolefin of the formula: CF CY CX H wherein Y is a hydrogen atom or a halogen atom (i. e. , fluorine, chlorine, bromine or iodine); X is a hydrogen atom or a halogen atom (i. e. , fluorine, chlorine, bromine or iodine); n and p are integers independently equal to 0, 1 or 2, provided that (n+p)=2; comprising contacting, in the presence of a phase transfer catalyst, a compound of the formula: CF C(R R )C(R R ), wherein R , R , R , and R are independently a hydrogen atom or a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine, provided that at least one of R , R , R , and R is halogen and there is at least one hydrogen and one halogen on adjacent carbon atoms; a and b are independently=0, 1 or 2 and (a+b)=2; and c and d are independently=0, 1, 2 or 3 and (c+d)=3; and at least one alkali metal hydroxide. The alkali metal hydroxide can be, for example, potassium or sodium hydroxide and the phase transfer catalyst can be, for example, at least one: crown ether such as 18-crown-6 and 15-crown-5; or onium salt such as, quaternary phosphonium salt and quaternary ammonium salt. The olef in is useful, for example, as an intermediate for producing other industrial chemicals and as a monomer for producing oligomers and polymers.

US Classification:

570164, 570168, 570169, 570177

Abstract:

Disclosed are improved fluorination processes and fluorine-containing compositions which involve introducing to one or more fluorination process compositions a water reactive agent in an amount and under conditions effective to decrease the amount of water in that composition. The water reactive agent is preferably introduced to the fluorination reaction process at a location proximate to the site of the fluorination reaction, or upstream of the fluorination reaction, in amounts and under conditions effective to produce a relatively lower concentration of water in the composition, and preferably throughout the fluorination process.
