实验步骤: 0.976 G. of 4'-cyano-4-hydroxy-biphenyl are dissolved in 10 ml. of absolute pyridine and reacted with 1.24 g. of chloroformic acid n-nonyl ester as in Example 1. The 2.026 g. of yellowish, turbid oil obtained according to the procedure described in Example 1 is dissolved in benzene and chromatographed on 90 g. of silica gel. Benzene elutes 1.646 g. of colorless crystals which are recrystallized from ether-hexane up to constant melting point and clearing point. The pure 4'-cyano-4-biphenylyl n-nonyl carbonate obtained melts at 53.0°-53.1° and has a clearing point of 70.0°. The compound is smectic up to 68.1°. UV (EtOH): ε 271 = 26600. of yellowish, turbid oil obtained chromatographed on 90 g of colorless crystals which are recrystallized from ether-hexane up to constant melting point and clearing point

实验步骤: A solution of 112 parts of potassium hydroxide in 1000 parts of water and 206.5 parts of nonyl chloroformate were added at equivalent rates over 2 hours to a stirred suspension of 69.5 parts of ground hydroxyl ammonium chloride in 1000 parts of ether at 0° C. to 5° C. The reaction mixture was stirred for a further 3 hours at 0°-5° C. followed by 18 hours at 25° C. and was then filtered to remove potassium chloride. The ether layer was separated, washed with water, dried, filtered and evaporated to constant weight at 40° C. under reduced pressure to give 190 parts of nonyl-N-hydroxycarbamate as a colourless oil. followed by 18 hours at 25° C. was then filtered to remove potassium chloride The ether layer was separated washed with water dried filtered evaporated to constant weight at 40° C. under reduced pressure
