Gf. Nichugovskii et Vs. Vasileva, DETERMINATION OF ACIDITY OF MINERAL AND SYNTHETIC OILS BY PH-METRIC BACK TITRATION TO A REFERENCE POINT, Russian journal of applied chemistry, 70(7), 1997, pp. 1147-1149
A highly sensitive procedure for determination of acidity of mineral a
nd synthetic oils was developed. It is based on back titration of spec
ified amounts of alkali with a sample under analysis to a specified pH
(reference-point procedure). Advantages and disadvantages of the proc
edure are discussed.
