Use

Dissolve 100g of phenylhydrazine hydrochloride in 200mL of warm H2O (60-70o) during 1-3hours, then add 1L of boiling EtOH. The solution is filtered, while still hot, through Whatman No 2 filter paper and cooled in a refrigerator. The precipitate is collected on a medium sintered-glass filter and recrystallised twice this way, then washed with cold EtOH, dried thoroughly and stored in a stoppered brown bottle. [Peterson et al. Anal Chem 29 144 1957.] Hough, Powell and Woods [J Chem Soc 4799 1956] boiled the hydrochloride with three times its weight of water, filtered hot (charcoal), added one-third volume of concentrated HCl and cooled to 0o. The crystals were washed with acetone, and dried over P2O5 under vacuum. The salt has also been crystallised from 95% EtOH, and it can be sublimed.
