1895A. Eiloart in Sci. Progress III. 503 If the temperature of racemisation2 lies below the ordinary temperature, the difficulty of separating the active isomers is accounted for. [Note] 2 This term is used to indicate the formation of the inactive aggregate from two isomers of opposite activity. 1927Arnall & Hodges Theoret. Org. Chem. II. vi. 59 Pinene and limonene undergo racemisation on simple heating. 1950R. C. Fuson Adv. Org. Chem. vi. 111 When l-2 iodoöctane is treated with sodium iodide in acetone solution..racemization occurs. 1966Phillips & Williams Inorg. Chem. II. xxix. 455 The complexes [Cr(C2O4)3]3- and [Co(C2O4)3]3- will not exchange oxalate with radioactive oxalate in aqueous solution under conditions in which complete racemization takes place. 1975Kingston (Ontario) Whig-Standard 5 Sept. 7/5 The ages were obtained by the so⁓called racemization method. This records the extent to which molecules of aspartic acid in a specimen have altered their configuration from the form that occurs in living bones to its mirror image. |
