NT CAT PC-5 CAS No.: 3030-47-5 Product Application Brief introduction. Chemical name: N,N,N′,N′,N″-Pentamethyldiethylenetriamine Alias: Pentamethyldiethylenetriamine Abbreviation: PMDETA English name: N,N,N′,N′,N″-pentamethyldiethylenetriamine Molecular formula: C9H23N3 Relative molecular mass 173.3 CAS No. 3030-47-5 Applications. Pentamethyldiethylenetriamine (PMDETA) is a highly active tertiary amine foaming catalyst, PMDETA has a strong foaming effect, which can improve the flow of foam and enhance the quality of products.PMDETA can also be used as a ligand for polyurethane foam catalysts and a ligand for functional polymerization materials. In addition, other applications are exemplified as follows. 1. Preparation of a two-phase amine absorber for capturing CO2. The two-phase amine absorber is a three-component system consisting of diethylenetriamine, pentamethylenetriamine, and water, and the total concentration of diethylenetriamine and pentamethylenetriamine in water is 4~5 mol/L, and the molar ratio of diethylenetriamine to pentamethylenetriamine is 1:4~4:1; these two organic amines alone do not have the ability to split the phase after absorbing CO2 in aqueous solution, but the two-phase amine absorber composed of the three-phase system But the two-phase amine absorber composed of this ternary system has the performance of phase separation, which is a homogeneous solution before absorbing CO2, and is divided into two phases after absorbing CO2 saturation. After saturated absorption, CO2 is enriched in the aqueous phase, and after phase separation, only the solution enriched in the CO2 phase needs to be regenerated thermally, thus greatly reducing the amount of enriched liquid required for regeneration, effectively reducing regeneration energy consumption, and also maintaining efficient CO2 absorption performance, which has a wide range of application prospects. 2.
