Ammoniacal gas liquor

Ammonium carbonate is very volatile, and consequently passing the gases < 1 i through water only causes the formation of a dilute ammoniacal gas liquor > gasworks), the direct distillation of which would lie expensive on account < consumed. 

Sulphates—Ammonio Sctlphatb—Diammonic sulphate—Ammonii sulphas (17.8.)—(NH ),SO,—132—is obtained by coHecting the distillate from a mixture of ammoniacal gas liquor and lime in H,SO,. It forms anh drous, soluble, rhombic crystals fuses at 140 (284 i ), and is deoomposed at 200 (392 P.) into NH. and H (NH.)SO..
