Abstract

130,968. U.S. Industrial Alcohol Co., (Assignees of Backhaus, A. A.). Aug. 7, 1918, [Convention date]. Distilling-plant.-Esters are prepared in a continuous manner by feeding an alcohol, an organic acid, and a catalyst, either separately or mixed together, to a column still while distilling off the ester formed. The production of methyl acetate from methyl alcohol, dilute or glacial acetic acid, and sulphuric acid is described. Using the apparatus shown in Fig. 1, sulphuric acid, dilute acetic acid, and methyl alcohol are fed continuously in regulated amounts from tanks 8, 12, 18 respectively by pipes 7, 11, 15 to a column still 1 of ordinary construction; at the commencement sufficient methyl alcohol is run in to seal all the plates in the still. Vapours of methyl acetate and alcohol pass off by pipe 22 to a dephlegmator 23; condensed alcohol runs back from the dephlegmator to the still by pipe 24, while methyl acetate vapours pass off by pipe 25 to a second column still 26. From this still the methyl acetate vapours pass by pipe 27<1> to a dephlegmator 28, condensed alcohol flows back by pipe 29 to the top of still 26, while the methyl acetate vapours pass on to a condenser 31. A pipe 27 leads methyl alcohol from the lower part of still 26 to the still 1. Water and sulphuric acid flow from the bottom of still 1 by a pipe 20. The apparatus shown in Fig. 2 is similar in all respects except the feed device. Sulphuric acid, acetic acid (in this case glacial), and methyl alcohol are fed from tanks 42, 46, 50 respectively to a mixing-tank 35 which contains a rotary stirrer 36, and after undergoing partial reaction in the mixing-tank, the mixture is fed to the still by pipe 34; an initial charge of methyl alcohol as before is fed to the still by pipe 50<a>. Specifications 130,969 and 130,970 are referred to.
