New Version of ASTM D664 Cuts Solvent Use by 50%

Jan 12 2018 Read 416 Times

Metrohm is pleased to announce that the ASTM released a new version of ASTM D664 for the potentiometric determination of acid number. The new version offers the possibility to reduce the required amount of solvent from 125 mL to 60 mL. Metrohm together with industry leaders investigated and proposed this possibility in a contribution towards green chemistry.

The acid number (AN) is a measure for acidic compounds in petroleum products. AN is crucial to assure the quality of petroleum products and is an important parameter in corrosion control.

AN is usually determined by potentiometric titration in nonaqueous solvent mixtures (see Metrohm AB-404). While ASTM D664 previously stipulated the use of 125 mL solvent per sample, the new version now offers the possibility to work with only 60 mL. This considerable reduction enables laboratories to save costs, reduce waste and thus contribute to a greener chemistry.
