Specifies an acid washing test. Gives some indication of the degree of refining but does not give a precise measure of the amount of unsaturated compounds present as different unsaturated compounds produce different colourations with sulphuric acid. Shaking together of equal volumes of the sample and 95 % (m/m) sulphuric acid. Comparison of the colour of the acid layer with that of standard…

Covers a method enabling quantities of chloride eceeding 1 mg in the test portion to be determined with an absolute error of 0,2 to 0,5 mg, according to the concentration of the standard volumetric solution used. The principle of determination is based on the conversion of chloride ions into weakly ionized mercury(II) chloride, using highly ionized standard volumetric mercury(II) nitrate solution…
