Abstract: 1495508 Oligomeric phosphorus ester condensates STAUFFER CHEMICAL CO 22 Nov 1974 [17 Dec 1973] 50667/74 Heading C2P [Also in Division C3] Phosphorus ester homo- and co-condensates (containing e.g. up to 60 P atoms) are freed from cyclic phosphorus-containing ester rings (Formula III infra) by reaction with hydroxy compounds (IV infra), with optional concurrent or subsequent neutralization of acid groups with an epoxy compound or orthoformate. The condensates are obtained by condensing one or more esters of formula at least one of which contains a 2-haloalkyl group, and wherein R<SP>1</SP> is R or OR, and each R is selected from (i) C 1-20  alkyl, C 2-20  2-haloalkyl (optionally containing a further halo substitutent), C 2-20  alkenyl, alkadienyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkadienyl, aryl, alkaryl, aralkyl and aralkenyl radicals (all optionally substituted by alkoxy, aryloxy, cyano or haloaryl) and (ii) radicals of formula where Q is a C 2-20  alkylene or haloalkylene radical, its valencies being from two vicinal carbon atoms, and each R<SP>2</SP> is selected from group (i) of the radicals defined for R. The condensation is effected at 110-250 C. optionally in the presence of a "nucleophili catalyst", and with removal of alkyl halide or alkylene dihalide formed, thus obtaining a condensate containing linkages of formula acid groups of formula >P(O)(OH), and fivemembered rings of formula The latter are converted to open-chain structures by reaction at 20-180 C. with where n is an integer and Y is H or a C 1-20  alkane or C 2-20  alkene radical optionally substituted by one or more non-interfering substituents, e.g. in accordance with the equations: wherein Z is the phosphorus-containing oligomeric chain. The examples describe the homocondensate of tris(2-chloroethyl) phosphate and the cocondensate of bis(2-chloroethyl) vinylphosphonate with trimethyl phosphate; their ring- opening reactions with water, methanol, ethanol or diethylene glycol; and their neutralization with ethylene oxide, trimethyl orthoformate, and the diepoxide of cyclohexenylmethyl cyclohexenecarboxylate. The ring-opened condensates are used for flameproofing textiles and polymers, e.g. polyurethanes, aminoplast resins and phenolic resins.

Abstract: 1,028,870. Chromatographic separation using baffles; contacting gases with liquids. ABCOR Inc. Dec. 23, 1963 [Dec. 24, 1962], No. 50801/63. Headings B1F, B1L, B1R and B1X. Chromatographic separation of fluids streams is achieved by using a large diameter chromatography column having transverse baffles therein which provide non-aligned flow passages, thereby reducing channelling and giving greater mixing of the fluid stream. In the preferred embodiment alternate baffles one with a central flow passage and the other with peripheral holes or providing annular holes, are used. In a specific embodiment (Fig. 1) for use in the gas chromatographic separation of benzene, trichloroethylene and diethylether using helium as a carrier gas, helium enters column 12 by way of flowmeter 22 and valve 24 at inlet 16. The column contains packing material 14 specific examples of which are disclosed e.g. detergent, and a series of baffles 40 a-c and 42 a-c, which are preferably in the form of discs and flat annuli respectively although other shapes may be used. A sample is added at 28 and leaves together with carrier gas at 18 after passage through a filter 44, passing to a detector 36 and flowmeter 38, line 30 and valve 34 make it possible to analyse only a portion of the effluent. The baffles may be regular or irregular shapes e.g. squares, rectangles or ellipses and have concave or convex surfaces. The flat annuli may not have holes exactly at their centre but disposed in regular or irregular patterns to induce a spiral or other flow pattern for the fluid stream while the area of the hole of a flat annulus is preferably equal to the area of the annular hole around the periphery of a disc. The baffles are preferably arranged alternately i.e. disc and flat annulus but other arrangements can be used, while the combination of disc and annulus preferably occurs at intervals equal to the diameter of the column. Spiral flow may also be induced by having elliptical baffles at an angle e.g. 30 degrees to the horizontal plane. It is stated in the Specification that baffles of they type disclosed may be used in other packed beds e.g. catalytic beds,packed reactor columns or adsorption towers or in fluid catalytic beds.

Title: Process for the production of lubricating oils or lubricating oil components
IPC: C10G45/60
Filed: 1965-12-06
Abstract: Lubricating oils or components therefor are produced from petroleum waxes by a process comprising the following steps:  (a) isomerizing a petroleum wax in the presence of hydrogen in a first zone over a catalyst containing a hydrogenation/dehydrogenation component and a solid acid-acting refractory support;  (b) isomerizing at least the portion boiling in the lubricating oil boiling range of the effluent from the first zone in the presence of hydrogen over a catalyst containing a hydrogenation/dehydrogenation component and a solid acid-acting refractory support in a second zone;  (c) separating the portion boiling in the lubricating oil boiling range from the effluent from the second zone; and  (d) dewaxing this portion.  The wax starting material may be one obtained from a residual oil or a distillate oil, preferably the former, and may be soft wax obtained by de-oiling crude wax.  Both isomerization zones may operate under the following conditions: temp. 316-492 DEG  C., pressure 35-140 atmospheres absolute, space velocity 0.1-5 litres of wax/hour/litre of catalyst, and hydrogen/wax mole ratio 5-50.  The catalyst in each zone may be at least one metal and/or oxide and/or sulphide thereof of Group II, V, VI or VIII of the Periodic Table.  Preferably, the catalyst in the first zone is sulphur-resistant, e.g. tungsten and nickel oxides and/or sulphides, and that in the second zone is sulphur-sensitive, e.g. platinum.  The support for the catalysts may be silica/alumina/BF3, silica/magnesia, silica/alumina/zirconia, alumina/fluorine, acid-treated clay, montmorillonite clay, a zeolite clay, or a molecular sieve.  The effluent from the first zone is preferably fractionated or flashed to remove hydrocarbons boiling below the lube oil range, and the wax from the dewaxing stage (d) may be recycled to the second isomerization zone.  The dewaxing stage is conventional, preferably by solvents, e.g. liquid propane, benzene, toluene, methyl ethyl ketone, or toluene/methyl ethyl ketone mixtures.  The process gives higher lube oil yields than known single stage processes.

Activated carbon is impregnated with monoethanolamine (M.E.A.) by passing M.E.A. vapour through the carbon. The impregnated carbon so produced is especially suitable for the removal of acid gases from inert gases as described in Specification 1,157,376, since it has a longer effective life in removing the acid gas than samples produced by impregnation with liquids. The carbon, which may vary in size from 4 to 325 mesh (U.S. Sieve) is impregnated with 1 to 50% of M.E.A. based on the weight of the M.E.A. and carbon. After use the spent carbon may be regenerated by exposure to further M.E.A. vapour, followed by blowing with inert gas to remove excess M.E.A. The apparatus shown has means for exposing- the carbon bed 4 to M.E.A. vapour from a boiler through line 10 or to the gas mixture to be treated through line 6. A condenser 26 and outlet lines 14, 28 for purified inert gas and separated acid gas respectively are also provided. M.E.A. is recycled by pump 34 from the collector 33 to the boiler 22.

A process for the separation of mixtures, especially hydrocarbon mixtures, by means of gas chromatography entails the use of at least two columns of different selectivity, the effluent from one column being quantitatively collected in fractions by freezing out the fraction from the gas stream in a small vessel, e.g. a U-tube immersed in liquid nitrogen, containing a filler material, such as diatomaceous earth, corundum or firebrick, which is suitably coated with a non volatile material such as a silicone grease or a high boiling hydrocarbon, injection of the frozen out fraction into a subsequent chromatography column being achieved by raising the temperature of the small vessel while carrier gas to the subsequent column is passing continuously through. The process is exemplified by the analysis of naphtha into its constituents, a flow sheet being provided in which four columns are employed, of which two use a silicone oil and the others tris-cyanoethoxypropane as the immobile liquid phase on conventional adsorbents, the carrier gas used being hydrogen.
