C3H6N2O3 = See also:

CO2+C2H5OH +N2 (alkalis), 2C3H6N2O3=2CO2+C2H5OH+2N2+See also:H2O+See also:C2H` (acids). On oxidation it yields nitro-See also:urethane. With a methyl alcoholic See also:solution of potash it yields a yellow precipitate, which is probably the See also:potassium See also:salt of nitrosocarbamic See also:acid, NK•NO•CO2K. Nitro-urethane, NO2•NH•CO2C2H5, formed by dissolving urethane in concentrated sulphuric acid and adding See also:ethyl nitrate to the well-cooled mixture (J. Thiele, ibid.), crystallizes in plates which melt at 64° C. and is soluble in See also:water. It has a strongly acid reaction, its salts, however, being neutral. Its See also:silver salt with methyl iodide gives a methyl See also:ether, which is readily split by See also:ammonia into methyl nitramine and methyl urethane (cf. A. P. Franchimont, Rec. See also:tray. chim., 1894, 13, p. 309). On reduction with See also:zinc dust and acetic acid it yields See also:hydrazine carboxylic ester.

Phenyl urethena, C6H5NH•CO2C2H5, is formed by the See also:

action of cyanformic ester on See also:aniline at too° C.; by the action of See also:absolute See also:alcohol on benzoyl See also:azoimide (T. See also:Curtius, Jour. See also:peak. Chem.12], 52, p. 214); and by the action of See also:bromine and See also:sodium ethylate on benzamide (E. See also:Jeffreys, Amer. Chem. Jour., 1899, 22, p. 41). It crystallizes in See also:long needles which melt at 51–52° C. and See also:boil at 227–228° C. (with partial de-See also:composition). It is easily soluble in alcohol and when heated in a sealed See also:tube yields aniline and See also:urea. With See also:phosphorus pentasulphide it yields phenyl See also:mustard oil.

Physiologically urethane has a rapid hypnotic action, producing a See also:

calm See also:sleep and having no depressant effect on the circulation. It is much used as an anaesthetic for animals. Di-urethane, NH (CO2C2H5)2, and hedonal, NH2CO2CH (See also:CH3). (C3H7), are also See also:narcotics, the latter being, in addition, a powerful diuretic. Phenyl urethane or euphorin has a physiological action more like that of acetanilide and See also:phenacetin than of urethane. It depresses the temperature and is an analgesic. It is of little value as an hypnotic.
