应用报告

本应用简报展示了如何根据不同的标准应用各种滴定类型来测定石油产品的总碱值。

Basic chemicals are added to petroleum products to prevent corrosion as they neutralize acidic components that form during the use and aging of these products. The base number (BN) gives an indication regarding the amount of these basic additives present, and it can be used as a measure for the degradation of the petroleum product.This Application Note describes the potentiometric determination of the base number according to ISO 3771, ASTM D2896, and IP 276 using the Metrohm Solvotrode easyClean and a fully automated OMNIS system.

使用 OMNIS 奥秘一代全自动电位滴定仪可根据 ASTM D664 和 ASTM D2896 标准全自动测定发动机油中的总酸值和总碱值。
