English name: 2,2-dimorpholinodiethylether,bis(2,2-morpholinoethyl)ether
Molecular formula: C12H24N2O3
Relative molecular mass: 244.0
CAS number: 6425-39-4
NEWTOP3

Physical and chemical properties

2,2-bismorpholinyl diethyl ether is a colorless to pale yellow liquid at room temperature, soluble in water;
Viscosity (25 ° C, mPa.s): 18
Density (25 ° C, g / cm 3): 1.06
Water soluble: soluble in water
Flash point (TCC, °C): 146
Amine value (mmol/g): 7.9-8.1 mmol/g
application
2,2-bismorpholinyl diethyl ether is suitable for use in water curing systems. It is a strong foaming catalyst. It can prolong the storage period of NCO components due to the steric hindrance effect of amino groups. It is suitable for TDI, MDI, IPDI, etc. Catalytic reaction of NCO and water in the system; 2,2-bismorpholinyl diethyl ether is mainly used in one-component rigid polyurethane foam systems, and also in polyether and polyester polyurethane soft foams, semi-rigid foams, The CASE material or the like is added in an amount of 0.3 to 0.55% of the polyether/ester component.
