Title: Improvements in or relating to terphenyls
IPC: C07C2/76
Filed: 1962-01-17
Abstract: In the production of terphenyls by the pyrolysis of a mixture of benzene and diphenyl, the formation of specific terphenyl isomer(s) is suppressed by adding the isomer(s) to the feed. Preferably the formation of para-terphenyl is suppressed to obtain a mixture or the orthoand meta-isomers having a low melting point.  The para-terphenyl in the feed is preferably recycled para-terphenyl separated from the product by distillation or crystallization.  Higher polyphenyls are also preferably recycled. Suitable feeds contain 70-80 parts by weight of benzene, 20-30 parts of diphenyl, 0,5-10 parts of selected terphenyl isomer and all higher polyphenyls formed in the process. Conversion is effected at 550 DEG -900 DEG C. at high turbulance, e.g. a Reynolds number of 10,000-500,000, in a single or multi-tube reactor.

Abstract: 1,145,961. Esterifying molten resins; foamed esterified resins. MONSANTO CHEMICALS Ltd. 5 Dec., 1967 [13 Jan., 1967], No. 1860/67. Addition to 1,106,489. Headings C3C and C3P. A thermoplastic resin containing alcoholic groups is subjected whilst in the molten state to the action of an esterifying agent whereby alcoholic groups of the resin are esterified. Suitable resins are polymers of unsaturated alcohols, particularly vinyl alcohol. Suitable esterifying agents are acid anhydrides particularly those of acids containing two carboxyl groups e.g. succinic, maleic and phthalic anhydrides. These result in polymers containing acid groups which may be reacted with base either during or after esterification to produce salts. The reaction may be carried out in a continuous mixing machine, a screw extruder or on mills-rolls. A blowing agent e.g. a volatile hydrocarbon may be included in the extruder so that a foamed product is obtained. An acid - group - containing resin may be cross-linked e.g. by reaction with a resin containing alcohol groups. A catalyst may be used for the esterification e.g. sodium acetate. In the examples a copolymer of ethylene, vinyl alcohol, vinyl acetate and monovinyl phthalate, is prepared by esterifying a copolymer of ethylene, vinyl alcohol and vinyl acetate with phthalic anhydride and its sodium salt prepared by treating with sodium hydroxide in methyl alcohol. In Example 2 sodium acetate and sodium methoxide are used as catalysts. In Example 3 maleic acid is used in place of phthalic anhydride. In Example 4 succinic anhydride is also used. In Example 5 a foamed resin is prepared using butane as blowing agent and silica as nucleating agent.

Title: Fireproof materials and products manufactured therefrom
IPC: C04B18/10
Filed: 1954-01-21
Abstract: Combustible material is removed from rice husks leaving a residue of non-inflammable material consisting essentially of silica by drying the husks, exposing the dried husks in closed space to a uniform temperature not lower than 30 DEG  C., moistering with water containing an enzyme, subjecting the moistened husks to a temperature of 40-45 DEG  C. in a closed space until the temperature of the husks has increased by catalytic decomposition to a temperature not exceeding 67 DEG  C, washing the solid residue and at least partially drying.  The enzyme may be obtained by distilling dust obtained from rice, wheat or oats.  Washing may be carried out at a temperature not lower than 20 DEG  C. with lime water in a vat provided with agitators below a metal screen whereon the required product collects. The lime water treatment may be preceded by treatment with water.  In some cases simple water washing is sufficient.  Long-fibre plants of high silica content, e.g. equisetum palustre or equisetum arvense, may be added to the husks being treated.  The product may be partially dried and mixed with solid glues or up to 20 per cent of wood chips or the like, or it may be dried, preferably with hot air until its moisture content is not more than 5-10 per cent and mixed with liquid or semi-liquid binders or glues, e.g. phenolic resins. The treated husks may be formed into sheets.

Title: Hydrocarbon separation process
IPC: C07C9/16
Filed: 1957-01-18
Abstract: In a process for separating straight chain hydrocarbons from mixtures by contacting the mixtures with molecular sieves in a fixed bed on which the straight chain hydrocarbons are selectively adstrbed, the molecular sieve is desorbed and regenerated by contacting with an olefine-containing gas and the straight chain hydrocarbons thereby recovered.  When applied to the adsorption of paraffins boiling in the gasoline range, ethylene, n-butylene or propylene, particularly the latter, is preferred as the desorption agent and adsorption and desorption are both carried out in the vapour phase at the same temperature, preferably 100-450 DEG F.  In one embodiment a fraction of a hydroformate boiling in the range C6-200 DEG F. is first dried and desulphurised by passing as a vapour preheated to 200-300 DEG F. over a molecular sieve material having a pore size of 4  or less and then over a molecular sieve material having a pore size of about 5 at 175-350 DEG F., a pressure of atmospheric to 400 p.s.i.g. and a space velocity of 0,1-5 vols. of liquid/vol. of adsorbent/hour. When straight chain hydrocarbons appear in the effluent the feed is stopped and a propylene-containing gas, e.g. a cracked refinery gas, preheated to 200-250 DEG F. and if desired dried and purified with a molecular sieve, is passed through the adsorbent at the same temperature as the first stage.  The paraffins are desorbed and removed and the olefine adsorbed.  On recontinuing the feed of hydroformate fraction the propylene is itself desorbed and paraffins again adsorbed.  In preparing a feed for an alkylation process, a mixture of normal and iso-butanes is passed over the adsorbent, the normal butane being adsorbed.  This is then displaced by passing over a cracked refinery gas and the n-butane effluent is passed through an isomerisation zone to give a mixture of n- and iso-butanes which mixture is again passed through the adsorbent, propylene being displaced and n-butane adsorbed.  The mixture of iso-butane and olefine can then be passed to an alkylation process.  Natural and synthetic zeolites are referred to as molecular sieve materials.

The side gears 9, 10, of the differential are free on the shaft 7 and secured respectively to drums 5, 6, to which the cables 3, 4, are attached, one cable passing over the top of one drum and the other cable underneath the other. The planet wheel 11 is secured to a spindle 12, which is mounted for rotation in a block 8 secured to the driven shaft 7, and is acted upon by a torsion spring 13 tending to rotate the planet 11 to tension the cables 3, 4. Reverse rotation of the planet 11 is prevented by a one-way ratchet 15, 14 (Fig. 3). For normal operation of the mechanism the differential device rotates solid with the shaft 7 on operation of the driving member 2, the pull by one cable being in the same direction as the push by the other. Should any slack develop in the cables the differential device comes into operation under the effect of the spring 13 to rotate the side bevels 9, 10, and their drums 5, 6, relatively to each other to take up this slack. This differential device may be provided at the driving end of the mechanism and the bevel 11 may be manually adjustable and retained by a spring catch. Applications of this mechanism are mentioned for the throttle controls of an aircraft or for a remote tuning control of a wireless receiver.
