The crude sulfate turpentine(CST) was recovered from the waste liquor of kraft pulp process. In order to research the higher ultilization of the CST, firstly it is necessary to define their components containing in the CST. The authors tried to the identification of offensive odor components, monoterpene hydrocarbon fractions and high boiling substances in the CST. And each components was studied to use the methods of fractional distillation, gas chromatography and Infra-red spectra. It was resulted that the existence of 27 components in the CST was analyzed to use gas chromatography. The organic sulfur compound (offensive odor component) in the CST was only dimethylsulfide, CH_3SCH_3 (1.6%). As the monoterpen hydrocarbons, α-pinene (63.3%), camphene (2.6%), β-pinene (5.0%), dipetene (4.9%) and ρ-cymene (0.8%) was confirmed. Among the high boiling parts (distilation residual, above bp 64°C/mmHg, 21%) containing in the CST, camphor (1.3%) and longifolene (8.8%) were confirmed. And the longifolene in the CST was purified to use gas chromatography and determined by Infra-red spectra.
