Aminoglycolysis and simultaneous hydrolysis-aminoglycolysis of poly(ethylene terephthalate) (PET) wastes by diethanolamine
(DEA) was attempted in the presence of xylene, with the aim of obtaining amine containing intermediates which have both hydroxyl and carboxyl end groups, which could be employed in polyurethane surface coatings for the first time.
It covers such amine types as Methyl Diethanolamine
(DEA), Monoethanolamine (MEA) and Di-isopropanolamine (DIPA), and makes recommendations on materials and process parameters to maximise amine unit efficiency and reliability.

The multi-center, randomized, double-blinded, placebo-controlled study evaluated the safety and efficacy of the Company's 3% Diclofenac Diethanolamine
NanoEmulsion cream in 104 patients with chronic pain due to osteoarthritis of the knee.
Unocal was cited for violations associated with the release of diethanolamine
in August and September 1994.
Known as copper-catalyzed dehydrogenation of diethanolamine
(DEA), the new process uses raw materials which have low volatility and are less toxic than those of other traditional processes.
The facility also will manufacture diethanolamine
(DEA) and triethanolamine (TEA).
The facility was cited for the notification violations associated with the release of the hazardous substance, diethanolamine
, which began on August 22 and continued until September 6, 1994.
Such a process is usually conducted at temperatures above 200[degrees]C by means of diethylene glycol with some coreagents like diethanolamine
 or catalysts .
After Johnson & Johnson, Procter & Gamble pledged to eliminate triclosan and DEP from all its products, Avon pledged to eliminate triclosan, Colgate-Palmolive pledged to eliminate formaldehyde donors, parabens, and DEP, and at least two-dozen companies agreed to eliminate the possible human carcinogen cocamide diethanolamine
The ZnO precursor solution are prepared by dissolving zinc acetate dehydrate (Zn (CH3COO)2 X 2H2O), in solution of ethanol and diethanolamine
at room temperature.
7 mmol/1 disodium p-nitrophenylphosphate hexahydrate, 25 mmol/l diethanolamine
and 1 mmol/l Mg[Cl.
