Triamine, diethylene

DETA has been produced by reaction of monoethanol amine [141-43-5] (MEA) and EDA with urea (42). In this process, MEA reacts with urea to form 2-oxa2ohdinone which then reacts with EDA to form the cycHc urea of diethylene-triamine. Hydrolysis of the ureaHberates the free amine. 

Both ethylene and propylene oxide have been used in the preparation of adducts from a variety of amines, including ethylene diamine and diethylene triamine. The latter amine provides adducts which appetu" free of skin sensitising effects.

Diethylene triamine pentaacetic acid is a chelating agent that sequesters metal ions so they cannot combine with other ingredients in a product. 

Diethylene triamine pentaacetic acid is used in soaps as a water softener, and to protect dyes and perfumes from combining with metals in solution. 

Sheratte55 reported the decomposition of polyurethane foams by an initial reaction with ammonia or an amine such as diethylene triamine (at 200°C) or ethanolamine (at 120°C) and reacting the resulting product containing a mixture of polyols, ureas, and amines with an alkylene oxide such as ethylene or propylene oxide at temperatures in the range of 120-140°C to convert the amines to polyols. The polyols obtained could be converted to new rigid foams by reaction with the appropriate diisocyanates. 

Rigid polyurethane foams were prepared at room temperature using eommercial polyols and polymerie 4,4 -diphenyl methane diisoeyanate, and used to study their reeyeling by aminolysis. The reaction products obtained by treatment with diethylene triamine at 180 C were evaluated as hardeners for epoxy resins. The exothermie heats of euring were determined over the temperature range 60-80 C by differential scanning calorimetry. A reaction order of 2.2-2.4 was obtained. 8 refs.

The dispersant used in these studies is Chevron Chemicals OLOA 1200, a polybutene of about 70 carbon atoms attached to a succinic acid group which is reacted with diethylene triamine to provide the basic anchoring group. Film balance studies showed that the adsorbed films have a film thickness of 50 X. This dispersant is supplied as a 50 w% solution in a mineral oil. It can be deoiled by adsorption from toluene onto silica with elution by acetone. In this paper the w% of dispersant refers to the deoiled material.
