发明名称 Process for preparing highly pure enantiomers of oxirane alcohols
摘要 Process for preparing highly pure enantiomers of oxirane alcohols, which comprises recrystallizing a mixture of the isomeric oxirane alcohols, in which the desired enantiomer is present in an excess of at least 60% ee, in a solvent or solvent mixture at a temperature just below the melting point of the oxirane alcohol. Oxirane alcohols prepared according to the invention are distinguished by high enantiomer purity. Ferroelectric liquid crystals, which contain highly pure enantiomers of oxirane alcohols according to the invention and/or derivatives derived therefrom, have particularly short switching times.
