Chinese name: 1,8-diazacycloundecene, diazabicyclo, DBU
English name: 1,8-Diazabicyclo (5.4.0) undec-7-ene
Molecular formula: C9H16N2
Relative molecular mass: 152.2
CAS number:6674-22-2
Physical and chemical properties
1,8-Diazabicycloundec-7-ene is a colorless to pale yellow transparent oily liquid with relatively low volatility, almost no odor, and alkaline. It is easy to change color when exposed to light, and it is hygroscopic and corrosive.
Relative density: 1.04~1.07
Viscosity (25 ° C): 14mPa.s
Water soluble: soluble in water
Flash point (TCC): >96 °C characteristics and use 1,8-diazabicycloundec-7-ene is used as a catalyst in the polyurethane industry, it is a very active low odor gel catalyst, mainly For applications requiring strong gel catalysis, including formulations containing alicyclic isocyanates or aliphatic isocyanates, because they are less reactive than aromatic isocyanates, they require a strong catalyst;
The activity of 1,8-diazabicycloundec-7-ene catalyst is obviously enhanced with the increase of temperature. For example, the catalytic rate constant of DBU to isocyanate-alcohol and isocyanate-water reaction at 70 ° C is 25 ° C, respectively. 67 times and 35 times of the time, while the catalytic activity of the commonly used bicyclic tertiary amine catalyst triethylenediamine is increased by 5 times and 6 times respectively;
The 1,8-diazabicycloundec-7-ene catalyst can be used in formulations such as a whole skin foam, a microcellular elastomer, and a rigid foam.
