Usage

Purification Methods

It is easily oxidised and has to be purified before use. This may be by recrystallisation from *benzene or by dissolution in pet ether, extraction into 1M NaOH solution, acidification of the aqueous phase with 1-6M HCl solution, back extraction into pet ether and final evaporation of the solvent. The purity can be checked by TLC. It is stored in ampoules under nitrogen at 0o in the dark. It crystallises in red crystals from pet ether. IR: 815m(C-S, C-H), 1260m(C-S), 1570sh(C=C) and 1612s(C=O)cm-1 . [Müller & Rother Anal Chim Acta 66 49 1973, Chaston et al. Aust J Chem 18 673 1965.]
