Dibromcotinine on hydrolysis yields oxalic acid, methylamine and 0-methyl pyridyl ketone: C10H10Br2N20+3H20+0= H2C204-ECH 3 NH 2 +C 5 H 4 N 000H 3 +2HBr; whilst dibromticonine yields methylamine, malonic acid and nicotinic acid: C10H8Br2N202+ 4H20=CH 3 NH 2 +CH 2 (CO 2 H) 2 +C 5 H 4 N CO 2 H+2HBr, or if heated with zinc and caustic potash, methylamine and pyridyl-ay-dioxybutyric acid.
Moreover, while methylamine, dimethylamine, and trimethylamine increase in basicity corresponding to the introduction of successive methyl groups, phenylamine or aniline, diphenylamine, and triphenylamine are in decreasing order of basicity, the salts of diphenylamine being decomposed by water.
The acetyl compound on reduction yields two of its nitrogen atoms in the form of ammonia and the third in the form of methylamine.
Nascent hydrogen reduces cyanamide to ammonia and methylamine.
Methylamine, CH 3 NH 2, occurs in Mercurialis perennis, in bone-oil, and herring brine.
and is readily soluble in water, but the solution is unstable and decomposes on standing, giving amorphous insoluble substances, and ammonium formate, oxalic acid, &c. An aqueous solution of hydrogen peroxide converts it into oxamide, (CONH 2) 2, and reduction by zinc and hydrochloric acid gives methylamine.
When boiled with caustic baryta it gives methylamine.
It is prepared by the action of aqueous or alcoholic solutions of the caustic alkalis on the nitroso-acidyl derivatives of methylamine (such, for example, as nitrosomethyl urethane, NO.
By the action of bleaching powder on methylamine hydrochloride, there is obtained a volatile liquid (methyldichloramine, CH 3 -N C1 2), boiling at 58-60° C., which explodes violently when heated with water, yielding hydrocyanic acid (CH 3 NC1 2 =HCN+2HC1).
When heated with water it is decomposed into carbon dioxide, ammonia, methylamine and acetic acid.
Hydrochloric acid at 200° C. decomposes into oxalic acid, carbon dioxide and methylamine, whilst an alcoholic solution of a caustic alkali gives dimethyl urea and oxalic acid.
Investigation of the cyanic ethers (1848) yielded a class of substances which opened out a new field in organic chemistry, for, by treating those ethers with caustic potash, he obtained methylamine, the simplest organic derivative of ammonia (1849), and later (1851) the compound ureas.
With baryta it yields methylamine, and when heated with concentrated hydrochloric acid to 260° C. it yields methyl chloride and nicotinic acid.
lithium in methylamine across the metal-nonmetal transition.
HTML The structure of liquid methylamine and solutions of lithium in methylamine.
By the action of bleaching powder on methylamine hydrochloride, there is obtained a volatile liquid (methyldichloramine, CH 3 -N C1 2), boiling at 58-60Ã‚° C., which explodes violently when heated with water, yielding hydrocyanic acid (CH 3 NC1 2 =HCN+2HC1).
Hofmann, Ber., 1881, 14, p. 2725), or of methylamine on acetylurethane (G.
Hydrochloric acid at 200Ã‚° C. decomposes into oxalic acid, carbon dioxide and methylamine, whilst an alcoholic solution of a caustic alkali gives dimethyl urea and oxalic acid.
With baryta it yields methylamine, and when heated with concentrated hydrochloric acid to 260Ã‚° C. it yields methyl chloride and nicotinic acid.
