Abstract
300,563. I. G. Farbenindustrie Akt.- Ges. Nov. 14, 1927, [Convention date]. [The subject-matter was laid open to inspection under Sect. 91 of the Acts, Feb. 12, 1928]. Addition to 285,090. Acetic anhydride.-In the process of the parent Specification for condensing acetic anbydride from a mixture of its vapour with water vapour by treatment with organic solvents in a column, a dephlegmation is placed at the top of the column, and the organic solvent, such as benzene, toluene, or benzene and trichlorethylene is admitted only at the bottom of the column.
