As mentioned above, Caira et al. implicated the stability of an ingoing cocrystallisation component as a factor in the preferential formation of a sulfadimidine cocrystal [36]. A year later,in a detailed structural analysis of three anthracene 16 cocrystals, Pedireddi et al. concluded that the ability of potential constituents to satisfy a network of hydrogen bonds dictated solid-state cocrystal formation [43]. Cocrystallisations of anthracene 16 with 4-chloro-3,5-dini-trobenzoic acid 17,3,5-dinitro-4-methylbenzoic acid 18 and 3,5-dinitrobenzoic...

Violent reaction with benzoyl chloride combined with KOH, Bt2, barium carbonate, CS2, Cr(OCl)2, Cu, Pb, HNO3, BaCOs, H2SO4, hot water, (CH3)2S04, dibromomalononitrile, sulfuric acid. Incompatible with acids, ammonium chloride + trichloroacetonitrile, phosgene, cyanuric chloride, 2,5-dinitro-3-methylbenzoic acid + oleum, trifiuroroacryloyl chloride. Reacts with heavy metals (e.g., brass, copper, lead) to form dangerously explosive heavy metal azides, a particular problem in laboratory equipment and drain traps. When heated to decomposition it emits very toxic fumes of NOx and Na20. See also AZIDES.
