Aldehyd-Ammonia

Take sulphuric acid, 6 parts; water, 4 parts; alcohol of 80 per cent., 4 parts; peroxide of manganese in fine powder, 6 parts. Dilute the acid with the water, then carefully add the alcohol, and next the manganese; agitate and distill with a gentle heat, from a spacious retort into a receiver surrounded with ice, and connected with the former perfectly air-tight. When 6 parts have distilled, re-distill this portion from its own weight of dried chloride of cal- 3 parts have come over, which must be again rectified in the same manner, bottle in a furnace, closing the mouth of the hollowed in the centre so as to fit the upper latter with a stone or clay cover in two pieces, part of the bottle, and defend it from the action of the fire. Connect the curved tube with a Wolffe's bottle half-filled with water, and placed in a freezing mixture; and when the iron bottle is sufficiently heated, introduce by the straight tube fragments of sulphur, and immediately close the mouth of the tube with a plug . The bisulphuret, as it comes over, falls to the bottom of the water. Separate it from the water, and distill over dry chloride of calcium.
