| description | FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method of synthesis of fluoroalcohol of the formula (I): H(CFR1CF2)nCH2OH where R1 means F or CF3 when n = 1; and R1 means F when n = 2. Method involves interaction of methanol with tetrafluoroethylene or hexafluoropropylene in the presence of source of free radicals. Synthesized reaction mixture is subjected for distillation either in the presence of a base or after contact of indicated mixture with a base. Fluoroalcohol of the formula (I) obtained by distillation has residue after evaporation 50 m.D., not above. Peroxide initiating reaction agent, UV-radiation or heating are used as the source of free radicals. Composite presents fluoroalcohol of the formula (I) with residue after evaporation 50 m.D., not above. Composite is used as dye solvent in production of carrier of information recording for laser recording and/or reading. Using fluoroalcohol of the formula (I) optical disk for laser recording and/or reading is made. Invention provides synthesis of fluoroalcohol that is useful for making laser recording and/or reading carrier. EFFECT: improved method of synthesis. 20 cl, 9 tbl, 2 dwg |
