Oxidizing agents chromic anhydride

The close relationship of eegonine to tropine is brought out by its Oxidation products, which when chromic anhydride in acetic acid is the agent used are tropinone, CgHijON (p. 74), tropinic acid, CgHi304N (P- 75) and ecgoninic acid, C HnOgN. The latter crystallises from benzene in colourless needles, m.p. 93°, and has been shown by Willstatter and Bode to W-methylpyrrolidone-2-acetic acid, and this was confirmed by Willstatter and Hollander s synthesis of the acid. [Pg.97]

Chromium trioxide (Cr03) is a strong oxidizing agent that appears in the form of deep-red hygroscopic crystals. Upon solution in water, it forms chromic acid that equilibrates with polymeric anhydrides.1... [Pg.1]

The most common oxidation agent is air, but oxygen is frequently used. Chemical oxidizing agents (nitric acid, dichromates, permanganates, chromic anhydride, chlorates, and hydrogen peroxide) are also often used. [Pg.624]

Chromic acid. Chromic acid or chromic anhydride is water soluble. It is available in the form of dark red needles. These crystals are highly soluble, very caustic, and act as oxidizing agents. The acid made from these crystals attacks any organic matter. When in its solid form (crystals), it can cause autocombustion phenomena when put in contact with paper. It is used as a component in litho and offset solutions. [Pg.275]

Chromic acid, in the form of its anhydride generally, dissolved in glacial acetic add, or as a water solution of potassium dichromate or sodium didiromate acidified with dilute sulphuric add, can also be used as an oxidising agent, not only in the case in hand, but also for the oxidation of alcohols, ketones, etc. In oxidation reactions, two molecules of chromic anhydride (Cr03) give three atoms of oxygen ... [Pg.311]

CHROMIC(VI) ACID (7738-94-5 solution, 1308-14-1) A powerful oxidizer. Violent reaction with many materials, including reducing agents, acetic acid, acetic anhydride, alcohols, alkalis, ammonia, anthracene, arsenic, combustible materials, ethers, finely divided metals, hydrogen sulfide, sulfuric acid, organic substances, red phosphorus, pyridine, selenium, sodium, sulfur, or other oxidizable materials. Incompatible with acetone, alkali metals, aliphatic amines, alkanolamines, alkylene oxides, amides, organic anhydrides, epichlorohy-... [Pg.318]
