UN1120 Butanols, Hazard Class: 3; Labels: 3— Flammable liquid. UN1212 Isobutanol or Isobutyl alcohol, Hazard Class: 3; Labels: 3—Flammable liquid Purification Methods tert-Butanol is synthesised commercially by the hydration of 2-methylpropene in dilute H2SO4. Dry it with CaO, K2CO3, CaS...
The primary alcohols, such as ethanol, n-propanol, n-butyl, and isobutyl alcohol, are oxidized to aldehydes and carboxylic acids. Therefore, significant metabolic acidosis may result from their ingestion. The secondary alcohols, such as isopropanol and sec-butyl alcohol, are converted to ketones, ...
The other solvent in step 1) may be any suitable solvent, such as but not limited to, water, ethanol, n-propanol, n-butanol, isopropanol, methanol, acetone, ethyl acetate, dimethyl carbonate, acetonitrile, dichloromethane, methyl ethyl ketone, methyl isobutyl ketone, 1-pentanol, methyl acetate...
However, the product may be isolated, for example, by using water and a water-immiscible organic solvent (e.g, the aliphatic, aromatic or halogenated hydrocarbon solvent, ether, t-butyl methyl ether, methyl isobutyl ketone, or the like) followed by phase separation, thereby removing the base ...
Tert-butanol is a metabolite of the gasoline additive methyl tert-butyl ether (MTBE). tert-Butanol also is used to manufacture methyl methacrylate plastics and flotation devices. Cosmetic and food-related uses include the manufacture of flavors, and, because of its camphor-like aroma, it also is...
The present invention primarily relates to the use of trans-tert-butyl cyclohexanol as skin irritation-reducing agent as well as compositions (formulations) having a skin irritation
