A quaternary ammonium salt of the formula: ##SPC1## ##EQU1## wherein A is a lower alkylene, a lower alkenylene or a lower alkadienylene; R.sub.1 and R.sub.2 are each lower alkyl which may be linked together directly or by an oxygen atom to form a saturated heterocyclic group; R.sub.3 is a lower alkyl, a halo (lower) alkyl, a lower alkynyl, phenyl (lower) alkyl which may have one or more halogen atoms as substituents on the phenyl ring, a lower alkenyl, a hydroxy (lower) alkyl, a carboxy (lower) alkyl or a lower alkenyloxycarbonyl (lower) alkyl; R.sub.4, R.sub.5 and R.sub.6 are each lower alkyl having 1 to 3 carbon atoms; X is an acid residue; and wherein the cyclohexyl ring may have one double bond, with the proviso that when the cyclohexyl ring has one double bond in the 1,2 position, A may not be ##EQU2## when X.sup.- is iodide, R.sub.4, R.sub.5 and R.sub.6 are all methyl; R.sub.1, R.sub.2 and R.sub.3 are all methyl or all ethyl, or R.sub.1 is methyl, R.sub.2 is ethyl and R.sub.3 is phenylisopropyl or isoamyl with the further proviso that when the double bond in the cyclohexyl ring is in the 2,3 position, A may not be ##EQU3## when X.sup.- is iodide, and R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are all methyl.
一种分子式为:##SPC1## ##EQU1##的四元铵盐,其中A是较低的烷基、较低的烯基或较低的烷二烯基;R.sub.1和R.sub.2均为较低的烷基,它们可以直接连接在一起,也可以通过氧原子形成饱和杂环基团;R.sub.3为较低的烷基、卤代(较低)烷基、较低的炔基、苯基(较低)烷基,苯环上可能有一个或多个卤素原子作为取代基,较低的烯基、羟基(较低)烷基、羧基(较低)烷基或较低的烯氧羰基(较低)烷基;R.sub.4、R.sub.5和R.sub.6均为具有1至3个碳原子的较低的烷基;X为酸残基;其中环己基环可能有一个双键,但当环己基环在1,2位有一个双键时,A不能是##EQU2##当X.sup.-为碘化物时,R.sub.4、R.sub.5和R.sub.6均为甲基;R.sub.1、R.sub.2和R.sub.3均为甲基或乙基,或者R.sub.1为甲基,R.sub.2为乙基,R.sub.3为苯基异丙基或异戊基,但是当环己基环中的双键在2,3位时,A不能是##EQU3##当X.sup.-为碘化物时,且R.sub.1、R.sub.2、R.sub.3、R.sub.4、R.sub.5和R.sub.6均为甲基。
