The results of the present study may be summarized as follows: (1) Oxygen recovery test has been carried out with various standard organic compounds and titanium tetrachloride containing vanadium oxytrichloride, phosgene and sucrose, applying the proposed carbon-reduction thermal decomposition method and the apparatus illustrated in the 1st report. In these experiments the authors have found that a portion of oxygen-containing impurities having low boiling points had been volatilized and careied out by the argon stream for purging after the sample had been put at the appointed place. In order to catch these volatile components and send them into the analytical system, a trap was attached to the apparatus. Using this improved apparatus, about 100 per cent of oxygen recovery has been obtained with each standard sample mentioned above. From these results, it has been proved that various volatile oxygen-containing impurities in titanium tetrachloride can be analysed by this method (2) It was found that oxygen in the non-volatile hydrolysed products of titanium tetrachloride can be retained as titanium dioxide out of the carbon-reduction-thermal decomposition system, and calculated from the detrmined value of titanium in this residue. (3) The sum of the oxygen content in the volatile and the non-volatile parts gives the total oxygen in titanium tetrachloride. (4) The precision of the oxygen per cent obtained by the carbon-reduction—thermal decomposition process is about 5 per cent in the terms of coefficient of variation (%) when a sample contains 0.004 per cent of oxygen, and oxygen recovery is about 100 per cent with titanium tetrachloride standard sample containing vanadium oxytrichloride and phosgene as impurities.
