otentiometric methods

recision;Titrimetry;Vegetable fats;Vegetable oils【摘要】: This International Standard specifies three methods (two titrimetric and one potentiometric) for thedetermination of the acidity in animal and vegetable fats and oils, hereinafter referred to as fats. The acidity is expressed preferably as acid value, or alternatively as acidity calculated conventionally.This International Standard is applicable to refined and crude vegetable or animal fats and oils, soap stock fatty acids or technical fatty acids. The methods are not applicable to waxes.Since the methods are completely non-specific, they cannot be used to differentiate between mineral acids, free fatty acids, and other organic acids. The acid value, therefore, also includes any mineral acids that may be present.【中国标准分类号】: X14【国际标准分类号】: 67_200_10【页数】: 16P.;A4【正文语种】: 英语
