tartralic, a. Chem.|tɑːˈtrælɪk| [ad. F. tartralique (Frémy 1838), arbitrarily formed on tartr-ique (f. tartre tartar1 + -ique), to indicate derivation from tartaric acid: cf. tartrelic. (Annales de Chimie LXVIII. (1838).)] In tartralic acid (also called ditartaric or isotartaric acid), C8H10O11 = 2C4H6O6{b1}H2O, an amorphous deliquescent substance obtained by heating tartaric acid. Its salts are tartralates.
1857Miller Elem. Chem. III. 332 If tartaric acid be heated to 374°, it fuses; two equivalents of the acid lose one equivalent of water, and thus become converted into a new acid, termed by Fremy the tartralic. If tartaric acid be kept longer in fusion half its basic water is expelled, and tartrelic acid is formed. Ibid., A soluble tartralate of this base is formed. 1868Watts Dict. Chem. V. 691 Ditartaric Acid,..called Tartralic acid by Frémy, Isotartaric acid by Laurent and Gerhardt. |
