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.[2] The IUPAC name is 4-[2-(2-morpholin-4-ylethoxy)ethyl]morpholine and the chemical formula C12H24N2O3.
Main section reference.[3]
DMDEE tends to be used in one-component rather than 2-component polyurethane systems.[4][5] Its use has been investigated in polyurethanes for controlled drug release[6] and also adhesives for medical applications.[7] Its use as a catalyst including the kinetics[8] and thermodynamics have been studied and reported on extensively.[9][10][11][12][13] It is a popular catalyst along with DABCO.
The material has been in use for some time and so the toxicity is generally well understood.[14] 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.[15][16]
