标准范围

给出了测定可溶于或几乎可溶于甲苯和丙-2-醇混合物的产物中酸性成分的方法。适用于水中离解常数大于10-9的酸的测定。该方法可用于指示在氧化条件下使用期间油中发生的相对变化，而不管所得油的颜色或其他性质如何。轴承腐蚀与酸值或碱值之间没有一般关系。

Gives a method for the determination of acidic constituents in products soluble or nearly soluble in mixtures of toluene and propan-2-ol. It is applicable for the determination of acids whose dissociation constants in water are greater than 10_-9. The method may be used to indicate relative changes that occur in an oil during use under oxidizing conditions regardless of the colour or other properties of the resulting oil. No general relationship between bearing corrosion and acid or base numbers is known.
