Determination of Organic Solvents Remained in Terpene Resin with Gas Chromatography and Its Application
摘要
Abstract
The determination technique and method of organic solvents remained in terpene resin was studied by gas chromatogra-phy. According to drawing standard curve, testing the precision and repeatability, calculating the lowest detection limit and determining recovery ratio, its feasibility was confirmed. Its practical application effect was further investigated. The results indicated that, the lowest detection limits determined by capillary gas chromatography for toluene, 1,2-dichlorethane and benzene were 0.2 mg/L, 1.7 mg/L, and 0.3 mg/L, respectively. For toluene determination, the standard deviation of determining precision is 0.04; recovery ratio and its standard deviation are 104.1% and 1.99, respectively. While applying the method to determine samples of terpene resin prepared in laboratory, it showed that there was only toluene as organic solvent in the resins and its residual contents was less than 25 mg/kg. No benzene and 1,2-dichloroethane were indicated in the resins.关键词
