Английская Википедия:DMDEE
DMDEE is an acronym for dimorpholinodiethyl ether but is almost always referred to as DMDEE (pronounced dumdee) in the polyurethane industry. It is an organic chemical, specifically a nitrogen-oxygen heterocycle with tertiary amine functionality. It is a catalyst used mainly to produce polyurethane foam. It has the CAS number 6425-39-4 and is TSCA and REACH registered and on EINECS with the number 229-194-7.[1] The IUPAC name is 4-[2-(2-morpholin-4-ylethoxy)ethyl]morpholine and the chemical formula C12H24N2O3.

Use as a polyurethane catalyst
DMDEE tends to be used in one-component rather than 2-component polyurethane systems.[3][4] Its use has been investigated in polyurethanes for controlled drug release[5] and also adhesives for medical applications.[6] Its use as a catalyst including the kinetics[7] and thermodynamics have been studied and reported on extensively.[8][9][10][11][12] It is a popular catalyst along with DABCO.
Toxicity
The material has been in use for some time and so the toxicity is generally well understood.[13] However, some sources say toxicity data is limited and work continues to acquire the necessary data and publish to ensure it is in the public domain.[14][15]
