The authors have investigated the influence of a mild acid isomerization catalyst, p-toluenesulfonic acid (TSA), on 4-butyl- (Ia) and 4-hexyl- (Ib) cyclohexanecarboxylic acids and their methyl esters (IIa, IIb). It is found that p-toluenesulfonic acid is an effective catalyst of cis-trans isomerization of 4-alkylcyclohexanecarboxylic acids and their esters; removal of water from the reaction medium raises the isomerization rate. Esters of alkylcyclohexanecarboxylic acids are isomerized at higher rates than the acids themselves. A probable mechanism of the acid-catalyzed isomerization reaction is proposed.
EFFECTS OF MOLECULAR LENGTH ON NEMATIC MIXTURES - 2. ANISOTROPIC AND DYNAMIC SCATTERING PROPERTIES OF 4-ALKOXYPHENYL 4-ALKYLCYCLOHEXANECARBOXYLATE MIXTURES.

The properties of nematic liquid-crystal mixtures of 4-alkoxyphenyl trans-4-alkylcyclohexane-carboxylates are studied as a function of temperature and their average molecular length. Mixtures are prepared with clearpoints near 72 degree C( plus or minus 3
