Patent GB-691866-A (GB)
Title: Manufacture of methyl acrylate
Inventor: BELLRINGER FREDERICK JAMES
IPC: C07C69/54
Filed: 1950-06-14
Abstract: Methyl acrylate is made by feeding betamethoxy-propionic acid into a heated reaction medium comprising an acidic catalyst and a substantial proportion of methyl beta-methoxy-propionate and methanol, withdrawing by distillation from the heated medium methyl acrylate substantially at the rate at which it is formed, together with methanol, water and methyl-methoxypropionate by using methyl acrylate and methyl methoxy-propionate as entrainers for the water and separating the methyl acrylate from the distillate.  Specified catalysts are sulphuric and phosphoric acids and their acid esters and sulphonic acids, e.g. p-toluene-sulphonic acid.  Preferred are sulphuric acid and its acid esters.  Quantities of 15 per cent by weight of catalyst are mentioned.  The amount of methyl-methoxy-propionate specified is 20 per cent and preferably above 40 per cent.  The preferred temperature is 120-140 DEG  C. Methanol may be fed to the medium or produced in situ by the de-alcoholization of methyl-beta-methoxypropionate.  Generally 1 mol. of methanol and preferably not more than 2 mols., to 1 mol. of acid is fed to the medium.  The distillate may be fractionated at such a temperature that only that amount of propionate required to remove water not entrained by the methacrylate is taken off and excess propionate is recycled.  To separate water from the entraining medium an additional entrainer may be used.  This entrainer may be methyl acrylate or benzene.  Methanol may be removed from the products by washing counter-current with water.  Methyl-betamethoxy propionate may itself be used to aid in the separation of its mixture with water and a small quantity of methyl acrylate may also be used, e.g. about 2 per cent calculated on the propionate fed.  The top layer of the separation which contains about 15 per cent of water is either fractionated to give water-free ester or preferably recycled to the reaction medium.  Vapour from the reactor may also be distilled to give a top distillate of methanol, methyl acrylate and possibly some water, from which the ester may be extractively distilled, and residue of propionate and water which may be separated by standing and treated as above. Examples are given in which sulphuric acid and p-toluene sulphonic acid are used as catalysts, it being stated that phosphoric acid and acid esters of sulphuric acid may be used in their place.

Patent GB-517270-A (GB)
Title: Process for selectively separating a constituent from a liquid mixture
IPC: B60L15/20
Filed: 1938-05-20
Abstract: 517,270. Distilling liquids. MUNEKATA, E. May 20, 1938, No. 15079. [Class 32] A volatile constituent present in admixture or in solution in a liquid system is separated by treating the system with a carrier gas so as to cause preferential evaporation of the volatile constituent and passing the mixture of gas and constituent through an absorption zone in which the constituent is removed from the gas. The vapour pressure of the constituents of the carrier gas common to the system and to the absorption zone is adjusted to be slightly greater in the absorption zone than in contact with the system. The liquid to be treated is placed in the tank 7 and is passed into the evaporating chamber 1 by a pipe 8 by the aid of a pump 6. The unevaporated portion of the liquid flows out through the pipe 8a. The chamber 1 is connected to the separating chamber 2 by two passages 4, 5 provided with a circulating fan 3 for the carrier gas. This gas contains the vapour from the chamber 1 and carries it to the chamber 2 when the vapour is absorbed by an absorbing agent stored in the reservoir 10 and pumped through the chamber 2 via a pipe 11 by a pump 9. In an example, a mixture of 30 per cent. alcohol, 20 per cent. acetic acid and 50 per cent. water at 50 ‹C. is put in the tank 7. The vapour pressure of the liquid is 160mm. of mercury and air is used as the carrier gas mixed with alcohol vapour and steam to raise the total pressure to nearly atmospheric pressure. The acetic acid in the solution, is contained in the carrier gas and is absorbed by an aqueous-alcoholic solution of calcium hydroxide. The precipitated calcium acetate is removed from the absorbing agent and the acetic acid recovered.
