DABCO
Overview:
Triethylenediamine, also known as triethylenediamine. White or light yellow crystals. Ammonia smell, this product is an organic synthesis intermediate, synthetic light-stabilizing material, widely used in polyurethane foam, elastomer and plastic products and molding process. It is also a polymer initiator and can be used as an ethylene polymerization catalyst and an ethylene oxide polymerization catalyst. Its derivatives can be used as corrosion inhibitors and emulsifiers.

Basic Information:
Abbreviations: TEDA, DABCO
English name: TRIETHYLENEDIAMINE
Chemical formula: C6H12N2
Physical and chemical properties
The normal state of TEDA is colorless or white crystals. It is easy to absorb moisture and deliquesce and agglomerate when exposed to air. It is alkaline and can absorb CO2 in the air and yellow. Easily soluble in acetone, benzene and ethanol. Pure TEDA is very toxic. Inhalation of saturated TEDA vapor can cause slight mucosal irritation, damage to the eyes, and skin irritation can cause allergies.
Relative density (25℃): about 1.14
Pure product melting point: 158-159℃
Flash point: 60℃
Boiling point: 174℃, easy to sublimate, slightly ammonia smell
Vapor pressure: about 67Pa at 21℃, 533Pa at 50℃, 7.7kPa at 100℃
Production method:
There are several methods for synthesizing TEDA at home and abroad. The general process is to pass the aqueous solution of amine or alcohol amine raw material through a reactor filled with catalytic zeolite at a certain flow rate, react at 320-400℃, 0.3MPa, and purify To get TEMA.
Piperazine and its derivatives are used to prepare TEDA. The efficiency of the product is high and the process is relatively mature to achieve industrialization. However, the production of piperazine and its derivatives in my country is small and the price is high. The production of TEDA using ethanolamine as a raw material has sufficient supply, simple operation, low cost, and industrialization in Japan. It is feasible in China.
Features and uses
Triethylenediamine is a tertiary amine compound with a double heterocyclic structure. It is mainly used as a gel catalyst for polyurethane foams. It is widely used in soft, semi-rigid, rigid polyurethane foams and elastomers. It can be used for epoxy resin curing catalyst, ethylene polymerization catalyst, propylene catalyst, acrylonitrile polymerization catalyst and ethylene oxide polymerization catalyst.
