Popis:	Odourless kerosene was treated by steam distillation, sulphuric acid washing and extractive crystallisation with urea, then examined for stability to nitric acid at 70° by use of a radiochemical procedure. Combinations of these processes can be used to produce an inert diluent with an improved performance factor of up to 8 over the untreated material. The improvement is attributed largely to removal of residual unsaturation. The results are compared with recent U.S. work on the subject and attempts are made to correlate the improvement factors with the chemistry involved in the different pre-treatment processes.
