Seite 106 - ... which yield from 1.5 to 2 per cent., or from benzal chloride, according to the reaction given. Pure benzoic aldehyde is a thin, colorless liquid, of great refractive power, and possesses a characteristic pleasant odor. It boils at 179° and has a specific gravity of 1.05. It is only very sparingly soluble in water, but miscible in all proportions with alcohol and ether, and is precipitated therefrom on addition of water. Exposed to the air, it rapidly oxidizes and is converted into crystalline...

Seite 136 - Wood. The comminuted wood is exhausted by boiling with alcohol; the greater part of the alcohol is then distilled off ; and the remainder of the decoction is evaporated to dryness and treated with sulphide of carbon, which dissolves retene and other substances, leaving a red-brown acid resin.

Seite 154 - CJJtOt-CeHt(OH)t, which may also be obtained by mixing aqueous solutions of quinone and hydroquinone. This beautiful substance is sparingly soluble in cold water, but dissolves readily in hot water to a reddish-brown solution that deposits splendid green crystals on cooling. It dissolves in alcohol and ether with a yellow color. When heated, it fuses to a brown liquid, and partly sublimes in green plates, the remainder decomposing and giving the yellow crystalline sublimate of quinone. On boiling...
