Patent GB-569412-A (GB)
Title: Butadiene stabilization
IPC: C07C7/20
Filed: 1942-10-20
Abstract: Butadiene-1.3 is stabilized against polymerization under storage and transport conditions by mixing with a small proportion of catechol or an alkylated catechol.  Catechol substituted by one or more alkyl radicals, e.g. methyl, ethyl, propyl, n-butyl, tert.-butyl or amyl, may be used, preferably a 4-alkyl catechol, wherein the alkyl group has not more than 5 carbon atoms, e.g. 4-methyl, ethyl, propyl or tert.-butyl catechol.  The proportion of stabilizer is generally up to about 5 per cent by weight of the stabilized composition, but solubility generally limits it to below 1 per cent.  Concentration of .01-.03 per cent or less usually suffice and do not affect the emulsion copolymerization of the butadiene with other compounds of the type of styrene, acrylic or methacrylic nitriles so that pretreatment of the stabilized butadiene prior to copolymerization is unnecessary.  In examples: (1) liquefied butadiene-1.3 containing 0.1 per cent catechol is stored in an evacuated steel bomb.  Unstabilized butadiene in a comparative test showed polymerization, and rusting of the container.  No such effects are observed with the stabilized product; (2) and (3) since peroxide formation promotes polymerization, oxidation tests were made with toluene containing 5 per cent butadiene which was subjected to the effect of air at a pressure of 1 atm. in an autoclave at 100 DEG  C.  Samples contained .02 per cent, based on the weight of the butadiene, of catechol and 4-tert.-butyl catechol.  The peroxide numbers after 2 1/2 and 5 hrs. are compared with those for the unstabilized solution.

Title: Improved method and plant for constant temperature condensation of components of vapour mixtures
IPC: B01D5/00
Filed: 1960-04-28
Abstract: In the condensation of a component of a vapour mixture, which component has a melting or coagulating point close to its boiling point and must consequently be condensed under substantially constant temperature conditions, the condensation is effected by heat-exchange with a non-contiguous boiling liquid and the vapour given off by the boiling liquid is condensed in a plurality of air-cooled tubes positioned vertically above the boiler and is returned by gravity to the boiler.  As shown (Fig. 1) a vapour <PICT:0905597/III/1> <PICT:0905597/III/2> mixture from a distilling column 1 is led through the tubes 6 in a boiler-type condenser 5 and the condensed component is withdrawn at 34.  The boiler shell 5 is filled with liquid which is kept at the boil by a steam-or hot water-jacket 30. Vapours from the boiling liquid are condensed in the finned tubes 13 (Fig. 2) of an air-cooled condenser 12 and returned to the boiler. Circulation of air across the tubes 13 is effected by a fan 18 (Fig. 1) and a tapering tubular member 16.  The boiling point of the liquid in boiler 5 is maintained constant by controlling the vapour pressure in the tubes 13.  This may be effected by controlling the amount of cooling air to the condenser 12, by the injection (through line 29) of an inert gas under pressure, by connecting the tubes to a suction device, by the provision of a safety valve 22 or by the provision of a valve 26 which can be controlled either manually or automatically under the influence of a thermostat 27 in accordance with the temperature in the boiler 5. Instead of a single condenser 12, a plurality thereof may be employed in various dispositions.
