108-45-2 Usage


The appearance of the high purity of the m-phenylenediamine is snow white flake solid used as a synthetic electronic grade polyimide material and epoxy resin curing agent.

Purification Methods

Purify the diamine by distillation under a vacuum followed by recrystallisation from EtOH (rhombs) and if necessary redistillation. It should be protected from light; otherwise it darkens rapidly. [Neilson et al. J Chem Soc 371 1962, IR: Katritzky & Jones J Chem Soc 3674, 2058 1959, UV: Forbes & Leckie Can J Chem 36 1371 1958.] The hydrochloride has m 277-278o, and the bis-4-chlorobenzenesulfonyl derivative has m 220-221o from H2O (214-215o, from MeOH/H2O) [Runge & Pfeiffer Chem Ber 90 1737 1957]. The acetate has m 191o. [Beilstein 13 IV 79.]
