Title:
PROCESS FOR PRODUCING PURIFIED FLUORINE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2003/037842
Kind Code:
A1
Abstract:
A process for producing a high−purity compound (formula 5) obtained from a compound (formula 1) having two reactive groups having the same reactivity by reacting the two reactive groups respectively with different compounds. The process comprises: reacting a compound (formula 1) such as 1,5−pentanediol with a compound (formula 2) such as trichloroethylene (TE) to obtain a reaction product (PI) comprising a compound (formula 3A) having TE which has added to each end and a compound (formula 3B) having TE which has added to one end&semi causing a fluorine compound (formula 4) reactive with the compound (3B) to act on the reaction product (PI) to obtain a reaction product (PII) comprising a compound (formula 5) and the compound (formula 3A)&semi and then subjecting the reaction product (PII) to solvent extraction with a fluorinated organic solvent and a fluorine−free organic solvent which are separable into two phases to thereby obtain the compound (formula 5) from the phase of the fluorinated organic solvent.
