Benzil osazone

Benzil Osazone. CeH5C( N NHCeH5)C( N NHCeH5)CeH5. [Pg.234]

Di-phenyUiydrazone benzil osazone. Needles. M.p. 225° (rapid heat.). [Pg.227]

Benzil osazone, in B-00038 17/-Benzimidazole-2-carboxaldehyde, B-00039 1 //-Benzimidazole-2-carboxaldehyde 2-quinolinylhydrazone, B-00040 2-Benzimidazolecarboxanilide, see P-00102... [Pg.975]

Experiment.—Benzoin (1 g.) in concentrated alcoholic solution is boiled for some time on the water bath with 1-5 c.c. of phenylhydrazine. On cooling the osazone of benzil crystallises. Melting point 225°. [Pg.223]

An identical compound is formed from benzil by the action of phenylhydrazine, and from benzaldehyde phenylhydrazone by autoxida-tion (Busch). The formation of osazones from a-hydroxyketones (and a-hydroxyaldehydes) will be discussed later (p. 298). [Pg.224]

Many oxidizing agents have been used, especially copper sulfate and other cupric salts. Potassium dichromate in acetic acid and manganese dioxide are good oxidants for benzil bis(phenylhydrazone). Nitrous acid has been used for the osazones of acetylated sugars and for phenylglyoxal bis(phenylhydrazone). ... [Pg.59]
