Di-n-heptyloxyazoxybenzene [2635-26-9] M 426.6, m 75 , 95 (smectic nematic) and 127 (nematic - liquid), pK j —5. Purified by chromatography on AI2O3 (" benzene), recrystd from hexane or 95% EtOH and dried by heating under vacuum. The liquid crystals can be sublimed in vacuo. [Mellifiori et al. Spectrochim Acta Part A 37(A) 605 1981 Dewar and Schroeder J Am Chem Soc 86 5235 1964-, Weygand and Glaber J Prakt Chem 155 332 1940]. 

Isobutyl chloroformate [543-27-1] M 136.6, b 123-127 /atm, 128.8 /atm, d 1.053, n 1.4070. It can be dried over CaCl2 and fractionated at atm press while keeping moisture out. Its purity can be checked by conversion to the phenyl urethane derivative with PhNCO [Saunders et al. J Am Chem Soc 73 3796 7957.] IR v 1780cm [Thompson and Jameson Spectrochim Acta 13 236 7959 Rose Justus Liebigs Ann Chem 205 227 1880]. 

Naphthacene (benz[b]anthracene, 2,3-benzanthracene, rubene) [92-24-0] M 228.3, m >300 , 341 (open capillary), 349 , 357 . Crystd from EtOH or benzene. Dissolved in sodium-dried benzene and passed through a column of alumina. The benzene was evaporated under vacuum, and the chromatography was repeated using fresh benzene. Finally, the naphthacene was sublimed under vacuum. [Martin and Ubblehode J Chem Soc 4948 7967.] Also recrysts in orange needles from xylene and sublimes in vacuo at 186°. [UV Chem Ber 65 517 1932, 69 607 7956 IR Spectrochim Acta 4 373 7957.]... 

Orange crysts by sublimation at 250-260°/3-4mm [UV Badger and Pearce Spectrochim Acta 4 280 1950]. Also recrystd from benzene under red light because it is chemiluminescent and light sensitive.
