IPC: B03B5/32
Filed: 1917-01-10
Abstract: 111,377. Mauss, W. Jan. 10, 1917. Wet-separating. - Ore pulp and the like containing crystalline and colloid constituents is passed through a centrifugal separator such as that described in Specifications 6478/18, 17724/14, and 8767/14, [all in Class 23, Centrifugal machines &c.] The pulp is passed through rapidly and the centrifugal separator is run at a high speed so that the pulp is acted upon for a short period only by a considerable force, the effect, being to cause settlement of the crystalline constituents without substantial settlement of the colloids so that the crystalline constituents can be discharged separately from the liquid and unsettled colloids. The process is usually carried out by running the separator at such a speed that the centrifugal force is from one hundred to two hundred times greater than that of gravity. When desired, the coarser crystalline constituents may be separated by gravity from the pulp before this is passed through the separator.

Title: Improved process for producing alkylated aromatic compounds
IPC: C07C2/68
Filed: 1940-01-10
Abstract: 537,894. Alkylated aromatic compounds. ABBEY, A. (Dow Chemical Co.). Jan. 10, 1940, No. 582. [Class 2 (iii)] Aromatic compounds are alkylated by a gaseous alkylating agent in the presence of a Friedel-Crafts alkylation catalyst by a continuous process which comprises contacting the alkylating agent in successive stages with reaction liquors each comprising the aromatic compound and Friedel-Crafts catalyst, recirculating a substantial proportion of the catalyst and continuously introducing aromatic compound and fresh catalyst into the reaction liquor of the last stage which the alkylating agent contacts. At least a proportion of the reaction liquor is withdrawn from each stage except the first and introduced into the next preceding stage. Reaction liquor and suspended catalyst are continuously withdrawn from the first stage, and a substantial proportion of the suspended catalyst so withdrawn is returned to the first stage. The desired alkylated product is separated from the remainder of the withdrawn reaction liquor. The catalyst is revived and replenished by being contacted with a body of the solid metal halide while in suspension in the reaction liquor. In an example benzene is alkylated with ethylene in the presence of an aluminium chloride complex in an apparatus as shown in the figure in which 1 and 2 are the reaction towers filled with packing. Ethylene is introduced into the foot of tower 1 through pipe 3 where it meets a descending stream of benzene and catalyst. Part of the ethylene reacts and forms ethyl benzene and part passes on to the tower 2 by pipe 4. The reaction liquor is drawn off from tower 2 and replenished in vessel 6 by contact with solid aluminium chloride in a basket 7. Part of it is returned to tower 2 through pipe 10, pump 11 and heater 12 after being replenished, and part is continuously withdrawn from pipe 15, and passed by way of pump 16 and heater 18 to tower 1 in company with part of the reaction liquor drawn off from tower 1 by way of sump 20, pump 25 and sludge storage tank 26. The reaction liquor not returned to the towers 1 and 2 is withdrawn from sump 20 as a crude product where it passes to a separator 22 to be fractionally distilled in the column 27, the unreacted benzene finished mono-ethyl benzene and high boiling residue being withdrawn through lines 28, 29 and 30.
