Title: Aliphatic olefins and manufacture thereof
IPC: C07C2/18
Filed: 1947-04-16
Abstract: Mono-olefins within the C12 to C15 range, prepared by interpolymerizing propylene with a C6 to C11 olefin which is a straight-chain olefin or mixture or a polypropylene or propylene-ethylene interpolymer, are condensed with phenol to give alkyl phenols which may be converted to polyvalent metal phenates for adding to hydrocarbon lubricating oils as stabilizing or anti-ring sticking agents.ALSO:Mono-olefins within the C12 to C15 range are prepared by interpolymerizing, in the presence of a phosphoric acid catalyst at approximately 375-500 DEG  F., 1 part by liquid volume of propylene with from approximately 0.2-10 parts by liquid volume of a C6 to C11 olefin which is a straight chain olefin or mixture, or a polypropylene or propylene-ethylene inter-polymer, and separating an acyclic olefin fraction boiling substantially from 325-520 DEG  F. The products are resistant to decomposition by hydrofluoric acid under alkylation conditions and may be used for alkylating benzene and the manufacture of detergents by sulphonation of the phenyl alkanes produced.  Suitable C6 to C11 olefins are n-hexene, heptene, octene, nonene or decene-1 or fractions of cracked paraffin wax of Fischer-Tropsch products.  Phosphoric acid on a support such as kieselguhr or active carbon is preferably employed at 400-460 DEG  F. and 200-600 p.s.i. with a space velocity of .02-.2 vols. liquid propylene/vol./hr., steam also being present.  Fractionation of the product, preferably under vacuum, gives a 325-520 DEG  F. fraction or a C12 cut of 330-420 DEG  F. and a C15 cut of 420-510 DEG  F. may be obtained.  For production of monophenyl alkanes, a fraction of I.B.P. 360-370 DEG  F. and F.B.P. 500-520 DEG  F. is preferred.  Light polymers in the C6-C11 range may be recycled to the polymerizer to increase the yield of C12-C15.  A mixture of propylene and ethylene may be passed down through the catalyst with previously formed interpolymers of C11 and below and the products fractionated.  The C12 to C15 olefins may be hydrogenated and converted to alkyl sulphonates by chlorsulphonation.  They may be alkylated with isobutene, converted to alcohols as by hydrochlorination and hydrolysis of the resulting alkyl chloride, or condensed with phenol to give alkyl phenols which may be converted to polyvalent metal phenates for addition to lubricating oils as stabilizing or anti-ring sticking agents.  Monophenyl alkanes produced from C12 to C15 cuts or from blends of C12 and C15 cuts give effective sulphonate detergents.

Patent GB-1103192-A (GB)
Title: Process for tempering glass sheets
IPC: C03B23/06
Filed: 1965-03-10
Abstract: A process of tempering glass sheets wherein one or a succession of glass sheets are rapidly cooled through the tempering range comprises cooling the major surfaces of each successive sheet at respectively different rates so that one surface cools faster through the said range than the other surface, the differential rate of cooling eventually causing the glass sheet to assume a curvature, which may be compound, different from that it possessed above the tempering range.  As described flat glass sheets are fed on rollers 20 and between radiant heaters 22 to a gaseous support bed 40 inclined at 5 degrees to the horizontal.  The support bed passes through a furnace heated by radiant heaters 54, 55 and the glass sheets are conveyed therealong by edge rolls 26.  Heated air is fed from a plenum chamber 43 into the individual modules 41 of the bed 40.  The curvature of the support bed 40 is altered so that the heated glass sheets can conform to it and so enter a quenching section with a predetermined curvature.  The characteristics of the bed are similar to those disclosed in Specification 1,021,842.  As the sheets are conveyed over the bed 40 they operate a sensing device 148 (Fig.3) which causes the last three rollers 26 and the first few 260 of the quenching section to be speeded up to quickly transfer the sheet from the heating section to the bending section, whereupon the seeed of the rolls reverts to the original speed.  The quenching section comprises a gaseous support bed 80 having the same contour as the bed 40. Each module 81 of said bed 80 comprises a prismatic body portion 160 having an upper surface containing a plurality of coplanar, arcuate grooves 162 extending outwardly from the centre of the module, which is connected to a plenum chamber below (see Fig.12). There is also an upper head assembly 92, adjustable in distance from the support bed, which conforms exactly to the shape of the lower bed.  The quenching section is divided into three stages 1A, 1B and II Stage II is the same length as 1A plus 1B.  Air is fed to each stage from fans, e.g. 89, which have valves 93, 94 for controlling the flow rate to the upper and lower chambers 80, 92. To maintain these at a uniform temperature cooling water is circulated through them.  The glass sheet curved during its passage through the heating section is conveyed through the quenching section by edge rolls 260. It is subjected to the greatest rate of cooling in stage 1A, and thereafter the cooling rate may be diminished.  In the case of a sheet convex upwards the upper <PICT:1103192/C1/1> <PICT:1103192/C1/2> <PICT:1103192/C1/3> <PICT:1103192/C1/4> surface would always be cooled faster than the concave surface. This controlled differential tempering causes the sheet to assume a final curvature different from that which it had on entering the quenching section.  The glass sheets may have any desired curvature, or be flat on entering the quenching section.  Also the sheets may be conveyed on porous beds, perforated plates, or rollers, or be balanced or suspended vertically.
