The acute handling hazards of several alkylalkanolamines were determined by investigating their potential acute toxicity and primary irritancy. Materials studied were N-methylethanolamine (MEA), N, N, -dimethylethanolamine (DMEA), N, N, -dimethylisopropanolamine (DMIPA), N-methyldiethanolamine (MDEA), and tertbutyldiethanolamine (BDEA). All these alkylalkanolamines were

Experimental exposure of four volunteers to 40-50 mg/m3 of dimethylethylamine (DMEA) for eight hours caused irritation of the mucous membrane of their eyes, subjective visual disturbances (haze), and slight oedema of the corneal epithelium. The thickness of the cornea showed

For nearly two decades, triethylamine and dimethylethylamine have been used as catalysts for phenolic urethane cold box binders in the foundry industry. During that time there have been reports of employees experiencing visual disturbances as a result of exposure to

Alkanolamine sulfates are the heat-stable salts formed in the fuel-gas desulfurization by using alkanolamines, and they can cause the deterioration of absorption performance and loss of absorbents. In this paper, a method was reported to regenerate three alkanolamines (monoethanolamine, MEA;

Supercritical fluid chromatography is routinely utilized by analytical separations groups in the pharmaceutical industry to efficiently handle separations for discovery medicinal chemistry purposes. Purifications are performed on samples ranging from a few milligrams up to hundreds of grams. Basic additives

Dimethylethylamine (DMEA) is an aliphatic tertiary amine, which is used as a catalyst in the mould core manufacturing. During 8 h, four healthy volunteers were exposed to four different DMEA air concentrations (10, 20, 40 and 50 mg/m3; 20 mg/m3

Phosphatidylethanolamine (PE) is a nonbilayer-preferring and fusogenic phospholipid. It is kept in the bilayer configuration by interaction with other phospholipids in biologic membranes. However, reorganization of the membrane phospholipids could lead to expression of the nonbilayer nature of PE and

The pH and reduction dual-responsive polypeptide nanogels with self-reinforced endocytoses were prepared through ring-opening polymerization of l-glutamate N-carboxyanhydrides, deprotection of benzyl group and subsequent quaternization reaction between γ-2-chloroethyl-l-glutamate unit in polypeptide block and 2,2'-dithiobis(N,N-dimethylethylamine). The nanogels were revealed to exhibit

1,2-Eliminations are a varied and extensive set of dissociations of ions in the gas phase. To understand better such dissociations, elimination of CH(2)=CH(2) and CH(3)CH(3) from (CH(3))(2)NH(+)CH(2)CH(3) (1) and of CH(4) from (CH(3))(2)NH(2)(+) are characterized by quantum chemical calculations.
