Properties: Yellow crystals from benzene + petr ether, mp 62°. Stable in an ordinary brown bottle for several years. A white coating (formed of p-tolylsulfonylmethylamide) does no harm. Insol in water. Sol in ether, petr ether, benzene, chloroform, carbon tetrachloride. Yields diazomethane on treatment with alkali.
Melting point: mp 62°
Use: In the laboratory prepn of diazomethane. Directions for use: de Boer, Backer, Rec. Trav. Chim. 73, 232 (1954). |
