By boiling an aqueous solu- tion of the barium salt of cyano-earbimido- amido-benzoic acid.—2. By heating (equal mols. of) ra-amido-benzoic acid and anhydrous oxalic acid for an hour at 180° (Griess, B. 16, 336; 18, 2412). Properties.—Small white plates. V. sol. hot water, m. sol. alcohol, insol. ether.—BaA 2aq. Mono-ethyl ether C0.2Et.CO.NH.C,H4.CO.,H(ethoxal-benzamicacid) [225°].

When heated above 225° it splits up into oxalic ether and carboxy-phenyl-oxamide. Amide-ether CO,Et.CO.NH.C6H4.CONH2. [1915°]. Got by heating m-amido-benzamide with oxalic ether. Gives with aniline the amide- anilide CO(NHPh)CO.NH.CfiH,CO.NH2 [c. 310°]. Anilide-ether C0.2Et.CO.NH.C(lH4.CONPhH [180°]. From w-amido-benzanilide and oxalic ether. Satiny needles.

Formed by heating methyl salicylate with phenylcyanate (Snape, B. 18, 2431). ra-CARBOXY-PHENYL-PHOSPHORIC ACID C„HJ(C02H).O.PO(OH)2. [201°]. From its chlo- ride and water. Scales, v. sol. water, alcohol, and ether. Water at 160° decomposes it into phosphoric and m-oxy-benzoic acid (Anschiitz a. Moore, A. 239, 333). Chloride C7H,C13P03 i.e. C6H4(COCl).O.PO.Cl2. (170°) at 12mm. S.G. 2?° 1-548. From w-oxy-benzoie acid (1 mol.) and PC15 (1% mols.). Further treatment with PC15 (1 mol.) produces G.H4C15P02 (178°) at 11 mm. This is probably C6H4(C0C1).0.PC14, and is con- verted by water into C6H4(C02H).O.PO(OH)2. A further quantity of PC15 converts C7H1C15P0, into C6H,C1.CC13. o-CARBOXY-0-PHENYL-PROPIONIC ACID H02C.C6H1.CH2.CH2.CO,H. [166°]. Formed by heating o-carboxy-benzyl-malonic acid to 190° (Wislicenus, A. 242, 39, cf. Gabriel a. Michael, B. 10, 2204). Prisms, v. sol. hot, si. sol. cold, water. CARBOXY-PHENYL-SEBACAMIC ACID C02H.C8H16.CO.NH.C6H4.C02H. [193°]. From its ether by saponification. Prisms. Mono-ethyl ether C0.2Et.C8H16.CO.NH.C6H4.C02H. [146°]. From sebacic ether and m-amido-benzoic acid (Pelliz- zari, A. 232, 146 ; B. 18, 215 ; G. 15, 550). m-CARBOXY-PHENYL-SUCCINAMIC ACID C2H2(C02H)CO.NH.C6H4.C02H. Benzamsuccinic acid. [223°]. Colourless prisms. Its ethyl- ether is formed, together with di-phenyl-succin- amide di-carboxylic acid, by boiling amido- benzoic acid with an alcoholic solution of suc- cinic ether. On heating to its melting-point it loses H20 and is converted into succinyl-amido- benzoic acid C2H2<^>N.CuHl.C02H [235°].

Crystal- line ; sol. ether, alcohol, and boiling water, insol. benzene.—AAg2: yellow pp. Di-methyl ether AMe2: [145°]; long colourless needles; m. sol. hot alcohol, si. sol. ether and benzene.

CARBYLAMINES v. Caebamines. CARDAMOMS, OIL OF. Employed in medi- cine as a carminative. 1. From Ceylon. The seeds of Elettaria major contain 3'5 p.c. of an essential oil which consists of a terpene (170°-178°), terpinene, a solid substance [61°], and terpineol CI0HI8O (205°-220°). The latter is converted by HC1 into di-pentene hydrochloride, C40H162HC1 [52°]
