Purification Methods
Check the IR first to see if free from OH frequencies. Triturate it with pet ether (b 30-60o) and decant the solvent. Repeat this 5times. The combined extracts are evaporated under reduced pressure to give almost pure compound as a readily crystallisable oil with a pleasant anise odour. It can be recrystallised from the minimum volume of EtOH at 50o (do not boil too long as it could react). It can be purified by vacuum distillation. [van der Kerk et al. Org Synth Coll Vol V 223 1973, Beilstein 12 IV 1214.] It is an IRRITANT and causes dermatitis; use gloves.
