Patent GB-1006783-A (GB)
Title: Organosilicon isocyanates
IPC: C07F7/18
Filed: 1963-09-05
Abstract: The invention comprises compounds of the general formula <FORM:1006783/C3/1> and silanes of the formula <FORM:1006783/C3/2> wherein each R is a divalent radical free from aliphatic unsaturation and is a hydrocarbon radical or a hydrocarbon ether radical having not more than one oxygen atom attached to any one C atom therein, each R1 is a monovalent hydrocarbon or halohydrocarbon radical free from aliphatic unsaturation, each R11 is divalent oxygen or R or haloarylene radical, X is a hydrocarbon radical, preferably lower alkyl, m has a value from greater than 0 to 1, n is 0, 1, 2 or 3, such that the sum of m + n averages at least 1 in the molecule, and s is 0, 1 or 2.  When m is 1 and n is 3, the compound is a silane; when m is 1 and n is 2, the compound is a disilylcarbane, a disiloxane or a disilylcarbane ether; and when m is 1 and n is less than 2, a polymer is obtained.  The compounds may be made either (1) by reacting <FORM:1006783/C3/3> with an alkenyl isocyanate or an alkenyl isocyanate ether, usually in the presence of a Pt catalyst, or (2) by reacting <FORM:1006783/C3/4> with <FORM:1006783/C3/5> to yield the product <FORM:1006783/C3/6> which decomposes on heating to yield phenol and the desired compound.  The silanes can be made by these methods, though the second method is restricted to phenoxy silanes because of the probability of phenol interchange if other hydrocarbonoxy radicals are present. The isocyanates are stable in the absence of moisture, but polymerize on exposure to moisture. Fillers, e.g. C-black, silicas (fume, aerogel, xerogel and treated), powdered metals, metal oxides and carbonates, talc, wood flour and asbestos, pigments and other additives may also be added. Examples are given of the above preparation of (1) <FORM:1006783/C3/7> which reacted spontaneously with <FORM:1006783/C3/8> to yield an organosilicon-urea polymer; (2) <FORM:1006783/C3/9> which reacted with ethylene diamine at room temperature to yield a gel urea structure; (3), (7) various silane and siloxane isocyanates.  In further Examples (5) a siloxane diisocyanate was reacted with a polyether to yield a foamed polyurethane; (6) the isocyanate of Example (2) was reacted with a hydroxy-terminated dimethylpolysiloxane; and (8) a silane of the formula <FORM:1006783/C3/100> was reacted with <FORM:1006783/C3/111> and the product heated to expel phenol to yield <FORM:1006783/C3/122> Uses.-As caulking, sealing and coating compositions.  The isocyanates are useful as catalysts in siloxane polymerization reactions, as described in Specification 836,954.  They may also be reacted with hydroxylated polyethers to provide silyl methane end-groups which may be polymerized or with polyesters to prepare polyurethanes, or in the preparation of organosilicon-urethane copolymers as disclosed in Specification 1,006784.  The compounds can also be reacted with organic or organosilicon compounds containing active hydrogen.

Patent GB-822682-A (GB)
Title: Hydrodesulfurization of petroleum fractions
IPC: C10G45/04
Filed: 1957-11-20
Abstract: Desulphurized petroleum fractions are obtained by heating a crude oil and separating from it, in the presence of hydrogen from an external source, in a flash drum at superatmospheric pressure, a vaporized portion including the naphtha, kerosene and diesel oil fractions, passing this vaporized portion together with gaseous hydrogen to an hydrofining zone where it is hydrodesulphurized, and then fractionating the hydrofined vapours and gases.  The vaporized portion of the crude oil is preferably that boiling up to 700 DEG  F. The pressure is preferably constant throughout the process and may be 100-1000 p.s.i.g.  The hydrogen used may be mixed with the crude oil before, during, or after heating and may contain non-interfering diluents, e.g. C2-4 paraffins, inert gases or steam.  Particularly suitable hydrofining conditions are: 500-800 DEG  F.; 100-400 p.s.i.g.; 1/2 -16 + v./v./hr.; 200-3500 SCF/bbl. H2 feed; 10-1000 SCF/bbl. H2 consumption; and molybdenum oxide or cobalt molybdate on alumina as catalyst.  The H2S formed in the hydrofining is preferably absorbed in a drum of metal oxide, e.g. zinc oxide, placed between the hydrofiner and the fractionator.  Other oxides which may be used are those of Ca, Ba, Fe, Mn, Ni, Cu, Co, Mo and Na.  In an example a crude oil is pumped at 430 p.s.i.g. in admixture with hydrogen-containing refining gas, through a furnace which it leaves at 800 DEG  F. and 225 p.s.i.g. and is passed to a flash drum. Sufficient additional hydrogen-containing gas is introduced to the flash drum to lower the pressure to that at which that portion of the crude boiling below 700 DEG  F. vaporizes. The vaporized hydrocarbon admixed with the hydrogen is passed to a hydrofiner operating at 735 DEG  F. and 210 p.s.i.g., using a cobalt molybdate on alumina catalyst.  The product gas from the hydrofiner is passed through a zinc oxide drum operating at 200 p.s.i.g. to remove H2S and separated into 2 naphtha, 1 kerosene and 1 diesel oil fractions in a fractionator operated at 190 p.s.i.g., a portion of the diesel oil fraction being sent as reflux to the flash drum.
