SYNTHESIS AND SOME PHYSICAL PROPERTIES OF TRANS-4- left brace beta -(TRANS-4 prime -N-ALKYLCYCLOHEXYL)-1 prime right brace -ETHYLCYCLOHEXANE-1-CARBOXYLATES.

Article abstract of DOI:10.1080/00268948408072105

A series of trans-4- left brace beta -(trans-4 prime -n-alkylcyclohexyl)-1 prime right brace -ethylcyclohexane-1-carboxylates, which show nematic phases, was prepared. Their transition temperatures and enthalpies were measured. Their bulk viscosities and birefringences were determined by extrapolation. The influence of terminal halogeno and alkyl groups on the N-I transition temperatures and the C-N transition enthalpies for the trans-4- left brace beta -(trans4- prime -n-alkylcyclohexyl)-1 prime right brace -enthylcyclohexane-1-carboxylates is discussed and compared with the influence for the 1-(trans-4- prime -n-alkylcyclohexyl)-2-(4 double prime -helobiphenyl-4- prime -yl)ethanes. The bulk viscosity as a function of the third power of the van der Waals radius of the helogeno group and the birefringence as a function of the van der Waals radius of the halogeno group for the 4-halophenyl trans-4 prime - left brace beta -(trans-4- double prime -n-propylcyclohexyl)-1 double prime right brace -ethylcyclohexane-1 prime -carboxylates are discussed.
