Abstract
PURPOSE:To perform a high-precise measurement of an oxygen absorbing rate, by a method wherein reference gas, having a known oxygen concentration, is caused to pass through an inorganic heat resisting receptacle, wherein a sample is placed, to measure an oxygen quantity which is consumed resulting from the reaction to the sample. CONSTITUTION:A sample, whose weight is accurately weighed, is collected in a reaction receptacle 3, and reference oxygen gas is led for bubbling. After an oxygen quantity, dissolved in the sample, is balanced with the oxygen quantity of the reference gas, a catalyst is added from the upper part of the reactor to start reaction. Gas, which is reduced in an oxygen concentration resulting from the reaction, is sampled at given intervals by a self-switching cock 6, it passes through a steam removing column 9, and after gas, produced from a petroleum product (sample), other than the reference gas component, is removed, it is led to an analyzer 10 to measure the quantity of oxygen in the gas. The application of the method permits the high-precise measurement of even a difference in initial reaction rate due to a difference in a catalyst quantity and a difference in a reaction speed due to a difference in a type and a lot between petroleum products.
