摘要：NOVELTY - An alkyl phenol separating method involves placing lubricating oil compound additive film in petroleum ether and heating to reflux to obtain thin film material. The thin film material is subjected to column chromatography by using activated silica gel as absorbent, petroleum ether as spraying agent, followed by collecting solution and evaporating to dryness to obtain component-I. The component-I is dissolved in ethyl ether, followed by adding hydrochloric acid to obtain acidified product. The acidified product subjected to column chromatography. USE - Method for separating alkyl phenol. ADVANTAGE - The method enables separating alkyl phenol with better commonality. DETAILED DESCRIPTION - An alkyl phenol separating method involves placing lubricating oil compound additive film in petroleum ether and heating to reflux to obtain thin film material. The thin film material is subjected to column chromatography by using activated silica gel as absorbent, petroleum ether as spraying agent, followed by collecting solution and evaporating to dryness to obtain component-I. The component-I is dissolved in ethyl ether, followed by adding hydrochloric acid to obtain acidified product. The acidified product subjected to column chromatography, followed by using activated silica gel as absorbent mixed solvent of ethyl acetate and petroleum ether as spraying agent, and collecting column chromatography solution. The collected solution is mixed with ethyl acetate solution of para petroleum ether.
