Triethylenediamine is solid at room temperature and is not convenient for use as a polyurethane catalyst. In industrial applications, it is often melted in small molecule diols and configured to be used as an alcohol solution with a mass fraction of 33% (or other concentrations).
Commonly used diols are dipropylene glycol monoacetate, propylene glycol, diethylene glycol monoacetate (diethylene glycol), ethylene glycol and so on.

Product Usage:
The active ingredient of polyurethane catalyst A33 is triethylene diamine, the solution prepared by 33% of triethylene diamine and 67% of monoconjugated dipropylene glycol is mainly used as gel catalyst for polyurethane foam, which is widely used in flexible, semi-rigid, rigid polyurethane foam, coating, elastomer, In polyurethane foaming system, isocyanate firstly reacts with triethylene diamine to generate active complex. The nature of the complex is very unstable, once the urethane bond is generated, it will be free, which is conducive to further catalyzing, triethylenediamine has a strong catalytic effect on the gel reaction and foaming reaction, especially on the polyurethane and hydroxyl catalytic effect is more selective.A33 is mainly used as gel catalyst for polyurethane foams, and it is widely used in flexible, semi-rigid, rigid polyurethane foams, elastomers, coatings, etc.

CAS No. 280-57-9
Water solubility Soluble
Appearance White crystal
Triethylenediamine DABCO Jeffcat TD-100 PC CAT TD100 Addocat 104 TEDA
Basic Information:
Abbreviation: TEDA, DABCO
English name: TRIETHYLENEDIAMINE
Chemical formula: C6H12N2
Physical and chemical properties
TEDA is colorless or white crystal, easy to absorb moisture in the air and agglomerate, alkaline, can absorb CO2 in the air and yellow. It is soluble in acetone, benzene and ethanol. Pure TEDA toxicity is very small, inhalation of saturated TEDA vapor will cause slight mucous membrane irritation, damage to the eyes, irritation of the skin will cause allergies.
Relative density (25℃): about 1.14
Melting point of pure product: 158-159°C
Flash point: 60°C
Boiling point: 174 ℃, easy to sublimate, slightly ammonia odor
Vapor pressure: about 67Pa at 21℃, 533Pa at 50℃, 7.7kPa at 100℃.
Preparation method:
There are several methods to synthesize TEDA at home and abroad, and the general process is to pass an aqueous solution of amine or alcoholamine raw material at a certain flow rate through a reactor filled with catalytic zeolite, react at 320-400°C and 0.3MPa, and then purify it to obtain TEMA.
The use of piperazine and its derivatives for the preparation of TEDA, the efficiency of the product is high and the process is mature to achieve industrialization. However, the output of piperazine and its derivatives in our country is small and the price is high, while the use of ethanolamine as raw material for the production of TEDA, the supply is sufficient, the operation is simple, the cost is low, and it is industrialized in Japan, so it is feasible in China.
Characteristics and Uses
Triethylene diamine is a kind of tertiary amine compound with double heterocyclic structure, which is mainly used as gel catalyst for polyurethane foam, and widely used in flexible, semi-rigid and rigid polyurethane foam and elastomer, in addition, it can be used as catalyst for epoxy resin curing, catalyst for ethylene polymerization, catalyst for propylene, catalyst for acrylolynes polymerization and catalyst for ethylene oxide polymerization.
