Organic synthesis.Purification Methods
Purify the ester by fractionation through a 45cm glass helices packed column or a 30cm spinning band column. [Sheppard J Org Chem 27 3756 1962.] It has been distilled through a short Vigreux column (p 11), and further purified by recrystallisation from Et2O at -40o as white crystals which melt at room temperature. NMR: 4.0 ( C3), and IR: 2250 (CN) and 1750 (CO) cm-1 . [Childes & Weber JOrg Chem 41 3486 1976, Beilstein 2 III 1587.]Methyl cyanoformate ?? ?? ? ???
