Crystallized from water or very dilute hydrochloric acid, slender needles of B 4 •3 HAuCl 4 (m.p. 186 °C) are obtained. When trigonelline is heated in closed tubes with barium hydroxide at 120 °C, it gives rise to methylamine , and, if treated similarly with hydrochloric acid at 260 °C creates chloromethane and nicotinic acid (a form of ...
