A range of 3-O-n-alkyl and 6-O-n-alkyl-D-galactitols, 2-O-n-alkyl-D-mannitols, 1-O-n-alkyl and 2-O-n-alkyl-D,L-erythritols and 1-O-n-alkyl and 2-O-n-alkyl-D,L-threitols was synthesized. Their thermotropic phase transition temperatures were compared with those of x-O-n-alkyl-D-glucitols (x = 1, 3, 4 and 6), x-O-n-alkyl-D-mannitols (x = 1 and 3) and x-O-n-alkyl-xylitols (x = 1, 2 and 3) in order to observe the influences of both the polyol structure and the alkyl chain x-position on the phase transition temperature. Lyotropic phase transition temperatures of all these compounds were also reported.
