反应详情

In tetrahydrofuran were dissolved 1.0 g of p-octyloxybenzoic acid chloride and 800 mg of p-hexyloxyphenol, and 500 mg of triethylamine was added to the solution and reaction was carried out with stirring overnight. The precipitate was removed by filtration, and the filtrate was concentrated, purified by using a silica gel column and recrystallized from ethanol to obtain 800 mg of 4-hexyloxyphenyl 4-octyloxybenzoate. The phase transition temperatures of the so-obtained compounds are as follows. ##STR142##
