Reaction Steps

This 4-hydroxy-4'-n-decyloxybiphenyl (0.5 g) was dissolved in dry pyridine (20 ml), followed by dropwise adding to the solution, commercially available (+)-p-(2-methylbutyl)benzoyl chloride (0.4 g), further pouring dry toluene (15 ml) in the mixture, sufficiently shaking at room temperature, further heating on a water bath at 60° C. for 3 hours, cooling down to room temperature, adding toluene (50 ml), twice washing with 6N hydrochloric acid (100 ml), further twice washing with a 2N alkali aqueous solution, several times washing with saturated NaCl aqueous solution to make the liquid neutral, drying over sodium sulfate, distilling off toluene, filtering through active carbon on heating using a mixed solvent of ethanol (20 ml) and ethyl acetate (20 ml), recrystallizing, filtering crystals deposited in a refrigerator, and drying to obtain the objective 4-n-decyloxy-4'-(p-(2-methylbutyl)benzoyloxy)biphenyl (0.3 g). Its phase transition points are shown in Table 3, sample No. 10. Further, its values of elemental analysis accorded well with its theoretical values as follows:
