화학적 성질
white to light yellow crystal powde용도
D-(+)-Camphoric acid is used primarily as a reagent in syntheses of crystalline structures. It is used in the preparation of polymeric transition metal dipyridylamine D-camphorate complexes.일반 설명
Camphoric acid is a diacid, generally prepared by the oxidation of terpene (+)-camphor. It can be used as a chirality inducing agent in some organic reactions.Purification Methods
Purify the acid by re-precipitation from an alkaline solution by HCl, filter it off, and recrystallise it from water several times, rejecting the first crop. It forms leaflets from EtOH and Me2CO and H2O and is insoluble in CHCl3. Its solubility in H2O is 0.8% at 25o and 10% at 100o, 50% in EtOH and 5% in ethylene glycol. The (±)-acid has m 202-203o. The (+)-1-methyl ester has m 86o (from pet ether) [] 20 +45o (c 4, EtOH), and the (+)-3-methyl ester has m 77o (from pet ether) []17.5 +53.9o (c 3, EtOH).
