Abstract：

This paper has carried out a feasibility study on the substitution of titration solvent for the determination of total acid value of jet fuel, focusing on the influence of four mixed titrating solvents on the determination results of jet fuel's total acid value is investigated, compared the total acid value of different production batches oil samples', and analyzed the accuracy, repeatability and reliability of the measured data,and the results show that the mixed titrating solvent by ethanol and water has the advantages of accurate test results, good repeatability, obvious end-point color mutation and easy control. It is recommended to promote the use of this experimental result.
