Synthesis of 2,6-bis(benzylidene)cyclohexanone and study of liquid crystal Behavior
2,6-二亚苄基环己酮液晶化合物的合成及性能研究

The liquid crystalline compound, 2,6-bis(benzylidene)cyclohexanone was synthesized using benzal-dehyde and cyclohexanone as raw materials, and tetrabutyl ammonium bromide as phasetransfer catalyst in the solution of sodium hydroxide. Effect of many factors, such as reaction time, reaction temperature and concentration of sodium hydroxide, was studied. The product was confirmed by IR, 1H-NMR and element analysis. The liquid crystalline behavior of compound was studied by DSC, optical polarizing micrographs a...
