    摘要： 268,749. Commercial Solvents Corporation, (Assignees of Edmonds, W. J.). April 3, 1926, [Convention date]. Acetone; formaldehyde; methyl alcohol. - In the production of butyl alcohol and acetone by fermentation, the entire series of operations, i.e. the charging and the discharging of the vat and the fermentation itself, is carried out in an atmosphere of the fermentation gases, whereby contamination of the gases with air is avoided; in this way the mixed gases-carbon dioxide and hydrogen-are obtained in a suitable condition for use in the catalytic synthesis of formaldehyde and methyl alcohol, either directly or after removal of part of the carbon dioxide. As shown, fermentation is effected in a vessel 1 from which the gases, escaping under slight pressure through a valve 3, are delivered to a holder 8 through towers 5 - - 7 in which volatile solvent vapours are removed; the tower 5 may be a water- or oil-scrubber and the towers 6, 7 may contain a solid adsorbent such as charcoal or silica gel. Part of the gases is withdrawn from time to time by a pump 12 through a vessel 11 in which sterilization is effected, for example by ultra-violet light, the pump delivering the gases under pressure to a container 13. When fermentation is complete, the valve 3 is closed, the mash is withdrawn through a pipe 16, and the gases enter the vessel 1 through a valve 14. The vessel may then be sterilized by steam admitted through a pipe 15, whereafter the valve 14 is closed, the valve 3 opened, and the fermentation of mash admitted through a pipe 2 is begun.
