SYNTHESIS AND LYOTROPIC PHASE-BEHAVIOR OF METHYL 3',4'-DI-O-HEXYL-BETA-LACTOSIDE AND 3',4'-DI-O-OCTYL-BETA-LACTOSIDE AND PARTIAL O-ACETYLATION OF METHYL 3',4'-DI-O-OCTYL-BETA-LACTOSIDE

Methyl 3',4'-O-isopropylidene-beta-lactoside was used as an intermedia te in the synthesis of the 3',4'-di-O-hexyl- and 3',4'-di-O-octyl-beta -lactoside. The following seven partially acetylated derivatives were prepared by partial O-acetylation of the dioctyllactoside: 6'- and 6-m onoacetate, 2',6- and 6,6'-diacetate, 2,6,6'-triacetate, and 2,2',6,6' - and 2,3,6,6'-tetraacetate. The lyotropic phase behaviour of some of these derivatives was studied.
