It should be pointed out that the above results are based on the same NAPHTHENIC ACID. For crude oils with the same acid value but different NAPHTHENIC ACID varieties, the total acid value is not the only factor that determines corrosiveness. The molecular structure and molecular weight of NAPH...
and its content accounts for about 90% of the acidic oxides. Its content varies greatly depending on the source of crude oil. The chemical properties of NAPHTHENIC ACID are similar to fatty acids. It is a typical monobasic acid and has all the chemical ...
Total acidity can be described as a measure of the total number ofhydrogen ionsthat occurs in a substance in the form of fixed and volatile acids. Therefore, this type of acidity typically includes potential hydrogen ions that can get released and hydrogen ions that are already in the solution...
