Patent GB-704416-A (GB)
Title: Improvements in or relating to thiaxanthones and the preparation thereof
Filed: 1951-11-14
Abstract: The invention comprises novel 1-(hydroxy alkyl-amino-alkylamino) - 4 - methyl thiaxanthones of general formula <FORM:0704416/IV(b)/1> where R is hydrogen, halogen, lower alkyl or alkoxy; R1 is hydrogen or lower alkyl; R2 is lower 2-hydroxy alkyl, and X is alkylene containing from 2-4 carbon atoms, having its two connecting linkages on adjacent carbon atoms.  The thiaxanthones are prepared by heating a 1-halo-7-R-4-methyl thiaxanthone with a diamine of formula R1 R2 N.X.NH2, preferably in pyridine as solvent.  Numerous examples are given of the preparation of 4-methyl thiaxanthones of the above general formula in which R is hydrogen, bromine, fluorine, chlorine, iodine, methyl, ethyl, isopropyl, n-butyl, iso-butyl, methoxy, ethoxy, n-propoxy, iso-butoxy or n-butoxy; R1 is hydrogen, methyl, ethyl or n-butyl; R2 is 2-hydroxy ethyl, 2-hydroxy propyl, 2-hydroxy-2-methyl propyl, or 2-hydroxy butyl; X is ethylene or 2-propylene.  The 1-halo-7-R-4-methyl thiaxanthones required as intermediates are prepared by cyclizing a 2-(2-methyl-5-halo-phenylmercapto)-4-R-benzoic acid in concentrated sulphuric acid.  The necessary 2-(2-methyl-5-halophenyl-mercapto)-4-R-benzoic acids are described in the copending Specification 704,414.  Intermediates of the general formula R1R2N-X-NH2 in which R1, R2, and X are the same as above are also described.

IPC: F02M41/16
Filed: 1923-10-26
Abstract: 231,212. Olsen Engine Syndicate, Ltd., and Olsen, S. D. Oct. 26, 1923. Regulating delivery by by-passes and by opening delivery valves; air vessels.-Fuel is supplied under pressure by a single pump to a series of accumulator chambers c and is delivered to the cylinders of an internal combustion engine through small orifices w and mechanically operated valves m, the duration of the opening of which is varied to control the quantity of fuel injected. The pump plunger b<1> is actuated by an eccentric e<1> on a shaft e, and delivers fuel to the chambers c through a spring pressed delivery valve b<4> and a passage a<2>. The pump has a spring-loaded relief valve b<5> in communiction with the pump chamber, which by-passes excess fuel back to the suction pipe when a predetermined pressure has been attained in the chambers c. This pressure may be varied by a screw adjustment for the loading spring of the valve b<5>. The chambers c are formed with depending bosses j in which are mounted the valves m, and air is imprisoned under pressure above the surface of the fuel to maintain the pressure in the chambers substantially constant. The valves m rest upon flexible diaphragms o, upon the side of which bear tappets t, actuated by cams g on the shaft e, through the intermediary of levers i. These levers i are pivoted at one end to an eccentric shaft h, and contact at the other end with the cams g; the tappets t bear on the middle of the levers, so that by rotation of the eccentric shaft h the duration of opening of the valves m may be varied, in order to control the supply of fuel to the engine. The diaphragms o may be concaved. According to the Provisional Specification, the depending member may be a transverse partition or cross-web.

Title: Removal of maleic anhydride from a maleic anhydride-containing gas
IPC: C07C51/573
Filed: 1961-07-28
Abstract: The maleic anhydride content of a gas containing 15 p.p.m. by volume to 5 molar per cent maleic anhydride is reduced by contacting the gas in a scrubbing zone with water or aqueous maleic acid solution to absorb maleic anhydride from the gas, the maleic acid solution containing maleic acid in an amount less than the saturation concentration by at least 5% by weight at the initial contacting temperature of the liquid, withdrawing scrubbing liquid from the scrubbing zone, recycling at least part of the withdrawn scrubbing liquid to the scrubbing zone after any necessary dilution to reduce the maleic acid content of the solution below the above-mentioned value, and withdrawing a gas containing less than 15 p.p.m. by volume of maleic anhydride from the scrubbing zone, in which process the scrubbing liquid temperature is maintained at a temperature at least 10  DEG C. below the adiabatic equilibrium temperature of the gas throughout the scrubbing zone.  The adiabatic equilibrium temperature is determined experimentally.  As described, reactor gas obtained from a maleic anhydride reactor is fed through heated tubing into a Venturi scrubber wherein said reactor gas contacts water or aqueous maleic acid.  The scrubbing medium containing maleic anhydride is then recirculated through the scrubber, the concentration of said scrubbing liquid being maintained by periodically draining a portion and adding fresh water.  In a preferred embodiment, reactor gas is first partially condensed in order to remove a portion of the contained maleic anhydride.  Any gas liquid contacting device, e.g. bubble cap columns, sieve tray columns or packed columns, may be used instead of the Venturi scrubber.  The feed gas temperature may be in the range 15-300  DEG C. and pressure atmospheric-500 p.s.i.g.  The volume ratio of gas to scrubbing medium is in the range 1-400 volumes of gas per volume of scrubbing medium.
