Abstract:

Each content of components of three-fraction mixed oil is determined with capillary gas chromatography. The simulative distillation data of three-fraction mixed oil are obtained according to the linear relation of the chromatographic result and distillation result. The determined result has good accuracy and precision. The total time of analysis does not exceed 20 minutes. The method can substitute for distillation method for the determination of the initial boiling point, final boiling point and naphthalene content of three-fraction mixed oil.
