Phenols with chromium trioxide

Oxidation of that compound with chromium trioxide in sulfuric acid leads cleanly to the desired ketone (67). Treatment with hydrobromic acid serves to demethylate the phenolic ether function (68). Direct... [Pg.327]

PHENOL, HEXAHYDRO- (108-93-0) Combustible liquid (flash point 154°F/68°C). Contact with oxidizers can cause fire and explosions. Violent reaction with chromium trioxide, nitric acid. Incompatible with strong acids, caustics, aliphatic amines, isocyanates. Attacks some plastics, rubber, or coatings. [Pg.961]

SAFETY PROFILE Poison by intravenous route. Moderately toxic by ingesdon and intraperitoneal routes. A severe eye irritant. Incompadble with phenol, p-naphthol, resorcinol or thymol in trituradon, potassium permanganate, chromium trioxide, pyrogallol. Combusdble liquid. VCTien heated to decomposidon it emits acrid smoke and irritadng fiimes. [Pg.866]

Incompatible with butylchloral hydrate camphor chloral hydrate chromium trioxide P-naphthol phenol potassium permanganate pyrogallol resorcinol and thymol. [Pg.460]

HIDROXILAMINA (Spanish) (7803-49-8) A powerful reducing agent. Aqueous solution is a base. Contact with water or steam causes decomposition to ammonium hydroxide, nitrogen, and hydrogen. Contaminants and/or elevated temperatures above (reported at 158°F/70°C and 265°F/129°C) can cause explosive decomposition. Moisture in air or carbon dioxide may cause decomposition. Violent reaction with oxidizers, strong acids, copper(II) sulfate, chromium trioxide, potassium dichromate, phosphorus chlorides, metals calcium, sodium, zinc. Incompatible with carbonyls, pyridine. Forms heat-sensitive explosive mixtures with calcium, zinc powder, and possibly other finely divided metals. Aqueous solution incompatible with organic anhydrides, acrylates, alcohols, aldehydes, alkylene oxides, substituted allyls, carbonyls, cellulose nitrate, cresols, caprolactam solution, epichlorohydrin, ethylene dichloride, glycols, isocyanates, ketones, nitrates, phenols, pyridine, vinyl acetate. Attacks aluminum, copper, tin, and zinc. [Pg.624]
