摘要

“Process for determining the distillation characteristics of liquid petroleum products by express mini-distillation and apparatus permitting implementation of this process”;Apparatus characterized by the fact that it includes:;a distillation flask dimensioned to receive 5 to 15 ml of a sample to be analysed,;organs for heating the distillation flask, with an adjustable constant heating intensity,;two inertialess temperature sensors permitting continuous measurement on the one hand of the true value of the temperature of a sample in the course of distillation in the liquid phase and the true value of the temperature of this sample in the vapor phase,;a device for continuous measurement of the pressure in the vapor phase of a sample in the course of distillation which includes a pressure detector and a capillary tube, and;organs for reception and exploitation of signals transmitted by the temperature sensors and the pressure detector.
