Applications & Uses

Occurrence

Reportedly present in sherry.

Uses

Synthetic and semisynthetic machine lubricating/cutting oil formulations have included isopropanolamine, diisopropanolamine, and triethanolamine, together with nitrites; consequently the EPA has promulgated standards regarding the composition of cutting fluids. No additional uses were found in the literature.

Uses

Amino-2-propanol is used to study the effect of temperature and water content on the molecular structure and hydrogen bonding of amino-2-propanol, which has been examined by Fourier transform near-infrared (FT-NIR) spectroscopy. Also used in used in the synthesis of protein kinase CK2 inhibitors used in the treatment of neoplasia and other infective diseases.

Uses

Amino-2-propanol can be used as a reactant to prepare: 5-methyl-2-oxazolidinone by oxidative carbonylation reaction using Pd(OAc)2/I2 catalyst. Bio-based polyurethanes by reacting with epoxidized soybean oil via ring-opening and amidation reaction. It can also be used as a solvent as well as a template to synthesize layered aluminophosphate containing a racemic mixture of isopropanolamine.

General Description

A colorless liquid with a slight ammonia-like odor. Less dense than water and soluble in water. Flash point 165°F. Corrosive to metals and tissue. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion. Used in plastics, paints, cutting oils, and specialized cleaning compounds.

Preparation & Synthesis

Preparation

By employing Salmonella, mutatant cobD, and aminopropanol
