![CHAPTER IJ MANUFACTURE OF WOOD ALCOHOL. Methods of and Materials Used in Manufacture. The destructive distillation of wood is almost the only method of obtaining methyl alcohol in the United States possessed of practical interest, although in Europe it has been proposed to manufacture it by the destructive distillation of peat (55) and it has been obtained as a by-product from vinasse (56). Methyl alcohol may also be prepared by a variety of synthetical reactions (57), and recently a process has been developed for obtaining it as a by-product in the manufacture of wood-pulp by a soluble sulphite process (58). The production from peat, vinasse and wood-pulp is incon- siderable, and more or less incidental; and the synthetical methods are at present too expensive to be practised on a commercial scale. The commercial demand for methyl alcohol is therefore (55) For description of prooess, see W. A. G. von Heidenstam, English Patent 2292, Feb. 5, 1900. . . (56) Vinasse is the residue remaining Jafter the distillation of fermented beet-root molasses. (57) The chief methods proposed are:— J A. From methane. m By chlorination in reflected sunlight (Berthelot, Compt. rend., 46, 916). Incomplete oxidation [Maiimene, Bull. soc. chim., (2), IS, 2431. Oxidation with ozone at ordinary temperatures [Otto, Ann. chim. phys., (7), 13 77] ^ 4 By passing methane and air over finely divided copper (Glock, Ger. Pat. 109014 of 1898; Coquillon, Z. Spiritusind., 23, 182). By oxidation with hydrogen peroxide, ferrous sulphate, monopersulphuric acid, ombined or alone (Lance and Elworthy, Eng. Pat. 7297, March 26, 1906). (2) (3) (4) (5) (6) <B. By combined L, _ . — . By oxidation at 30-50° C., using tan bark as a oontact substance (Hausmann & Co., Ger.
