실험 절차

After adding 17 g of nonanic acid chloride to 200 ml of pyridine dissolved with 47 g of hydroquinone, the mixture was heated for 2 hours. Following neutralization of hydrogen chloride, the crude of 4-octylcarbonyloxyphenol was obtained by extracting with chloroform. The crude compound was purified by passing through silica-gel column to obtain pure 4-octylcarbonyloxyphenol (J). (I) was reacted with (J) to obtain the compound (G) same procedure as example 14. (G) was a smectic liquid crystal compound having the SC* phase. The phase transition points of (G) were shown in table 4.
