Novel chemical compounds of the general formula K+A-, in which K+ is a 5- or 6- membered heterocyclic ring having 1-3 hetereo atoms, which can be independently N, S, or 0; with the proviso that at least one of the hetereo atoms must be a quaternized nitrogen atom having a -R'CN substituent, wherein R' is alkyl (C1 to C12); the heterocyclic ring having up to 4 or 5 substituents independently chosen from the moieties: (i) H; (ii) halogen or (iii) alkyl (C1 to C12) , which is unsubstituted or partially or fully substituted by further groups, preferably F, Cl, N(CnF(2n+1-x)Hx)2, O(CnF(2n+1-x)Hx), S02(CnF(2n+1-x)Hx)2 or CnF(2n+1-x)Hx where 1
通用公式K+A-的新化合物,其中K+是一个含有1-3个杂原子的5-或6-成员杂环,这些杂原子可以独立地是N、S或O;但其中至少一个杂原子必须是一个具有-R'CN取代基的季
铵氮原子,其中R'是烷基(C1到C12);该杂环最多有4或5个取代基,可以独立选择自以下基团:(i) H;(ii) 卤素或(iii) 烷基(C1到C12),该烷基未取代或部分或完全被进一步的基团取代,优选为F、Cl、N(CnF(2n+1-x)Hx)2、O(CnF(2n+1-x)Hx)、S02(CnF(2n+1-x)Hx)2或CnF(2n+1-x)Hx,其中1
