phthalamIc

[Eng. phthal ( ic ), and amic.j Derived from or containing phthalic acid and ammonia. phthalamic acid, s. Chem.: C ,NO3=(C ). H2 ö. A crystalline phthăl-a-mine, s. [Eng. phthal ( ic ), and a mine.] phthăl-dě-hyde, s. [Eng. phth ( alic ), and alde IMG:content-1010.png:[blocks in formation] Chem.: C8H4O3=C6H4.CO.O. Phthalide, Pyroalizaric acid. Obtained by distilling phthalic acid, or by treating phthalic acid, with one molecule of phosphoric chloride. It crystallizes in fine shining needles, melts at 120°, boils at 277°, and di olves in alcohol and ether. With boiling water it is slowly resolved into phthalic acid. phthalic-ethers, s. pl. phthal-ide, subst. [English phthal ( ic ); -ide .] [PHTHALIC-ANHYDRIDE.] phthal-i-dine, s. [Eng. ( na ) phthal (ene); -id(e), and -ine .] Chem .: C8HgN=C6H7 C6H12 } N. A crystalline body pro duced by heating, in a water-bath, a mixture of an alcoholic solution of nitro-phthalene and ammonium sulphide, evaporating almost to dryne , extracting with dilute hydrochloric acid, and saturating with potash. It forms beautiful needles of the color of realgar, melts at 22, boils at 260°, is slightly soluble in water, but very soluble in warm alcohol and ether. Its salts are mostly soluble in water and in alcohol. phthal-i-mide, subst. [Eng. phthal ( amic ), and imide.] Chem.: C8H5NO2=(C8H4O2)" } N. A colorle , in odorous, and tastele body, obtained by heating phthalate or phthalamate of ammonia. It crystallizes in six-sided prisms, insoluble in cold water, slightly soluble in hot water, easily soluble in boiling alcohol and ether. It is not attacked by chlorine or by weak acids, but on boiling with an alcoholic solution of potash it evolves ammonia and forms pota ium phthalate. phthăl-o-sul-phür'-ic, adj . [Eng. phthal ( ic ); o connect., and sulphuric .] Derived from or containing phthalic and sulphuric acids. pht halo sulphuric-acid, s . Chem.: C8H6SO7. Formed by heating phthalic acid to 100-105°, for some time, with exce of sulphuric anhydride, and leaving the product exposed to moist air. Its salts are uncrystallizable, and their aqueous solutions decomposed by boiling. phthal-ÿl, s . [ Eng.phthal (ic); -yl.] Chem.: The hypothetical radical of phthalic acid. IMG:content-1011.png:[graphic] phthalyl-chloride, s. marine; gõ, pot, phthanite without decomposition, and does not solidify on cooling. It is very unstable, and if kept in imperfectly closed ve els decomposes, depositing large crystals of phthalic anhydride.
