Applications.
Pentamethyldieth , ylenetriamine (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. A methanol gasoline power accelerator.
The accelerator consists of: isooctanol, aminoacetaldehyde diethyl acetal, 1,5-
cyclooctadiene, 2-acetylbenzofuran, propargyl alcohol, n-propanol, zinc
naphthenate, dinonyl naphthalene sulfonic acid, dipolyoxyvinyl aliphatic amine,
and pentamethyldiethylenetriamine. The preparation method includes: a. Add
isooctanol, aminoacetaldehyde diethyl acetal, 1,5-cyclooctadiene, 2-
acetylbenzofuran to the reaction kettle and stir the reaction for 40-50 minutes
at 60-62°C with closed ultrasonic stirring, b. Mix n-propanol, zinc
naphthenate, dinonyl naphthalenesulfonic acid and stir for 15-25 minutes; c.
Add propargyl alcohol, the mixture in step b, dipolyoxyvinyl fatty amine,
pentamethyl diethylenetriamine, add them to the mixture in step a in turn, stir
for 20~25 minutes at 33~35℃, and then cool down to obtain.
