Ostwald, Veruxuulteclwfta Lehre (Leipzig, 1887). _ SECTION IV. THE ORGANIC CHEMICAL MANUFACTURES. ALOOHOLS AND ETHIIRS. Methylic Alcahol.--CH, .OH, a liquid boiling at 65'5 to 66, is formed on the dry distillation of wood. Leaf-bearing trees yield it in larger proportion than the conifers. For the distillation there are commonly used horizontal iron retorts, heated in the same manner as gas retorts, though in general not above 500. Occasionally,1, -age, upright retorts are used, or, in France, cylinders of sheet-iron (Fig. 377). Such a cylinder, A, has in its upper half an opening 0, to which a connecting-piece is screwed 'rd-gig? on. 'Upon the cylinder 1S laid the cover, which is screwed fast as soon as the cylinder has been filled with wood. The cylinder itself is lowered by means of the crane, D, into a cylindrical furnace, B, closed above with the stone cover, E. The products given off on the application of heat pass through the pipe, b (Fig. 373), Whi0h is connected with the cylinder and bent in a zigzag manner, through the refrigerating apparatus c, set in the support d, to which cold water is conveyed through f, whilst the heated water escapes at k. Acetic acid, tar, and wood-spirit are liquifiecl, and flow into the vat g, in which the tar is chiefly deposited. The lighter liquids run through m to the second vat, IL. The combustible gases escape through the pipe i, into the open air, or into the furnace, though their value as fuel is but small. In large works there are used, instead of the wooden vats, cisterns of cement or masonry sunk into the ground, each being connected with the next ...
