Claims (1)

Способ определения кислотного числа масла или жира, включающий отбор пробы масла или жира, смешивание его с реагентом, отличающийся тем, что в качестве реагента используют реагент, состоящий из 0,1-0,3 молярного раствора триэтаноламина и 0,01-0,03 молярного раствора соли сильного основания и сильной кислоты в водном растворе изопропилового спирта, а после смешивания определяют значение рН полученной смеси, по значению рН вычисляют концентрацию ионов водорода, при этом кислотное число масла или жира находят по калибровочной кривой, построенной в координатах «кислотное число масла или жира - концентрация ионов водорода смеси».A method for determining the acid number of an oil or fat, including sampling an oil or fat, mixing it with a reagent, characterized in that the reagent is a reagent consisting of a 0.1-0.3 molar solution of triethanolamine and 0.01-0.03 a molar solution of a salt of a strong base and a strong acid in an aqueous solution of isopropyl alcohol, and after mixing, the pH of the resulting mixture is determined, the concentration of hydrogen ions is calculated from the pH value, while the acid number of the oil or fat is found from the calibration curve constructed in coordinates "the acid number of oil or fat is the concentration of hydrogen ions of the mixture."
