Is Dodecyldipropylenetriamine the same as Laurylamine Dipropylenediamine?

Yes. Both names are used for CAS 2372-82-9, also described as N,N-bis(3-aminopropyl)dodecylamine. It is a polyamine with three amine functions, so it is not the same as laurylamine or a simple C12 monoamine.

Why should total amine value be compared for this material?

Total amine value expresses the available amine functionality and is a useful basis for salt formation and stoichiometric formulation calculations. Compare it with water, colour and the agreed test method rather than treating the product name alone as the full specification.

Does an acid salt of Dodecyldipropylenetriamine have the same behaviour as the neat amine?

Not automatically. Acid type and neutralisation level change the supplied composition and can alter solubility, dispersion and formulation behaviour. The selected acid, molar ratio, solvent and use conditions must be evaluated together for the finished inhibitor system.
