You may melt your metals and cast them into the most beautiful moulds you can; they will never excite me like the forms which this molten earth flows out into.
Benzamide, C6H5ï¿½Conh2,, crystallizes in leaflets which melt at 130° C. It is prepared by the action of ammonium carbonate on benzoyl chloride.
It crystallizes in yellow needles which melt at T 7 T ° C., and are only sparingly soluble in alcohol.
It is formed by reducing diortho-dinitrodiphenyl with sodium amalgam and methyl alcohol, or by heating diphenylene-ortho-dihydrazine with hydrochloric acid to 150° C. It crystallizes in needles which melt at 156° C. Potassium permanganate oxidizes it to pyridazine tetracarboxylic acid.
Nicotelline crystallizes in needles which melt at 147° C. and is readily soluble in hot water.
