摘要

(57) Abstract Formula (ii): R _{fA m} (CH₂) _nSCN [in formula, R _f, the perfluoro alkyl group, or is the perfluoro alkyl group of C₅ - C_{38 where} at least of C₂ - C_{20 it} possesses one ether oxygen atom; n is 1 - 3; m is 0 or 1; A, O, S and CO₂, N (R₁) R₂, CON (R₁) R₂, SO₂ N (R₁) R₂ or (OCH₂ CHR₃) is _aO; a approximately 15 is from 3; R₁ H or is the alkyl group which possesses approximately 4 carbon atoms from 1; R₂ is the alkylene of C₁ - C₁₂; And as for R₃, H or CH₂ Cl is] being manner for preparing the thio cyanate; As for the manner, formula (i): The to fluorine of R _{fA m} (CH₂) _nI [in formula, R _f and A, as for m and n, something which is defined at description above it is,] the iodide which is converted, the thiocyanate M ⁺ (SCN) where M is the sodium or the kalium ^- with, formula (R₄) ₃ (R₅) N ^+Y- [in formula, R₄ is the butyl; R₅ is methyl or the butyl; Y Cl and Br, I or HSO₄ is] under existing of the catalytic converter which includes quarternary ammonium salt reacting, to fluorine formula (ii) it defines at description above discloses the manner which gives the thio cyanate which is converted.
