This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1885 edition. Excerpt: ...kept wet by means of very cold water, a constant current of cold air being at the same time made to pass over them. The pipe D leading from the retort is several feet long, and is advantageously passed through a wooden screen, in order that the radiated heat of the retort and brickwork of the furnace, may be intercepted as much as possible. There are two methods of carrying out the process. In one the dry pulverulent ingredients are mixed together, and the resulting gas passes over into the water placed in the receivers. In the other the lime is made into a pap with water, and the ammonia salt, in coarse powder, being added to it, the whole is rapidly blended together, before closing the retort and applying heat. In either case a proportionate quantity of water is put into the condensers, and the operation is nearly similar; but the latter method requires the least heat, and so far as the receivers and refrigerators are concerned is perhaps more easily managed. It is that always followed when sulphate of ammonia is employed. An aqueous solution of ammonia is in constant demand in the laboratory, both as a reagent and for precipitating the oxides of the heavy metals. Liquid ammonia is now very frequently made by distilling the sulphate with caustic soda, the value of the residual sulphate of soda, and the ease of manipulation, compensating for extra cost. the accompanying woodcut. Steam is forced into large receptacles, which are filled with gas-water, by which means the carbonate of ammonia is volatilized. When lime is added, ammonia gas is evolved, and if this is conveyed into weak sulphuric acid, sulphate of ammonia will be the resulting product. Among the plans having for their object the production of an ammoniacal solution, more or...
