Brochure: Determination of acid number in crude oil and in petroleum products in accordance with ASTM D8045 – Precise and reproducible results in 60 seconds

The acid number is an important quality parameter for crude oil. As a rule, the acid number in crude oil is determined in accordance with ASTM D664. This method has disadvantages, however. Metrohm has therefore joined together with other leading companies in the petroleum industry and developed an alternative test method to ASTM D664. The new method describes thermometric titration and was published under the number ASTM D8045. The present brochure compares ASTM D664 with ASTM D8045.
