Abstract

Cyclohexane derivatives of formula I EQU R.sup.1 --(A.sup.1).sub.m --Z.sup.1 --A--Z.sup.2 --(A.sup.2).sub.n --R.sup.2 I PA0 wherein R.sup.1 and R.sup.2 are each H, an alkyl group which has 1-10 C atoms and in which one or two CH.sub.2 groups can also be replaced by O atoms, F, CL, Br, CN or --O--COR, A.sup.1 and A.sup.2 are each 1,4-phenylene, 1,4-cyclohexylene, 1,3-dioxane-2,5-diyl, piperidine-1,4-diyl, 1,4-bicyclo(2,2,2)-octylene or pyrimidine-2,5-diyl groups which are unsubstituted or substituted by 1-4 F atoms, A is a 1,4-cyclohexylene group which is substituted in the 1-position and/or 4-position by alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy, each of which has 1-5 C atoms, F, Cl, Br and/or CN and which can also carry 1 or 2 further F, Cl or Br atoms and/or CN groups, Z.sup.1 and Z.sup.2 are each --CO--O--, --O--CO--, --CH.sub.2 CH.sub.2 --, --OCH.sub.2 --, --CH.sub.2 O-- or a single bond, R is an alkyl group which has 1-5 C atoms, m is 1 or 2 and n is 0 or 1, it being possible, where m=2, for the two groups A.sup.1 to be identical or different from one another; and the acid addition salts of those compounds which are basic, are suitable for use as components of liq…
