Physicochemical properties:

1,8-Diazabicyclohexadec-7-ene is colorless to light yellow transparent oily liquid with relatively low volatility, almost odorless and alkaline. It is easy to change color when exposed to light, hygroscopic and corrosive.

Relative density: 1.04~1.07

Viscosity (25℃): 14mPa.s

Water solubility: soluble in water

Flash point(TCC):>96°C

Properties and Uses:

1,8-Diazabicyclohexadec-7-ene is used as a catalyst in the polyurethane industry, it is a very active low-odor gel catalyst, mainly used in applications requiring strong gel catalysis, including formulations containing alicyclic isocyanates or aliphatic isocyanates, which are less active than aromatic isocyanates and therefore require very strong catalysts.

1,8-Diazabicycloundec-7-ene catalyst activity is significantly enhanced with increasing temperature, for example, the catalytic rate constants of DBU for isocyanate-alcohol and isocyanate-water reactions at 70 °C are 67 and 35 times higher than those at 25 °C, respectively, whereas the catalytic activity of the commonly used bicyclic tertiary amine catalyst triethylenediamine is increased to 5 and 6 times its original catalytic activity, respectively;.

The 1,8-diazabicycloundec-7-ene catalyst can be used in formulations for integral skin foams, microcellular elastomers, and rigid foams.

The main use of DBU is as an excellent organic base deacidifier for drug synthesis. It can replace organic bases such as triethylamine, N,N-dimethylphenylamine, pyridine and quinoline, and is widely used in organic synthesis and semi-synthetic antibiotics, and obtains more satisfactory results in the dehalogenation reaction. It is widely used in the production of cephalosporin semi-synthetic antimicrobial drugs, such as ammonia and dichloroethane in the presence of DBU reaction to produce piperazine. It can also be used for epoxy resin hardener, rust inhibitor, can be formulated with high slow corrosion inhibitor, catalyst for other chemical reactions.

DBU in the application of epoxy resin DBU in the room temperature to 40 ℃ range of almost no curing reaction with the epoxy resin, and the temperature rises to 100 ℃ in 15min can make the epoxy resin gel. In epoxy resins, DBU is mainly used as a curing accelerator for epoxy resins used in the encapsulation of integrated circuits and electronic components. When used in the form of DBU salt, DBU is dissociated from it when it is heated during encapsulation to promote curing.

The combination of DBU and linear phenolic resin is a light yellow solid, which changes the disadvantage of DBU being easily hydrolyzed in humid environment. Therefore it consists of epoxy molding compound for IC encapsulation with good resistance to humidity and heat and high pressure steaming performance.

The catalyst catalyzes both gel and foam, providing a more balanced catalytic performance for the foam and gel reactions of rigid foams, it is a stronger catalyst for the reaction between water and isocyanate (foam reaction), and it also has moderate catalytic properties for the reaction of polyol plume isocyanate, and it is a strong initial catalyst for the foam reaction. It is a strong initial catalyst for the foam reaction. In addition to hard foam, it can also be used as an auxiliary foaming agent for molded soft foam and semi-hard foam. It has stable and adjustable performance in combination materials and can be stored for a long time.

Storage and transportation:

It should be sealed and stored in dry, cool and ventilated warehouse

Packing:

200KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the package cover as soon as possible after the original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the performance of the product.
