Title: Manufacture of chlorinated ethanes
Inventor: PAGE NORMAN JAMES LE
IPC: C07C17/10
Filed: 1964-03-31
Abstract: 1,056,522. Chlorinated ethanes. IMPERIAL CHEMICAL INDUSTRIES Ltd. March 31, 1964 [Feb. 10, 1964], No. 5436/64. Heading C2C. Tetrachloroethanes and / or 1,1,2 - trichloroethane, in any desired proportion, are produced by establishing an equilibrium in a continuous system comprising a packed reaction column surmounted by a reflux condenser by (1) feeding ethylene into the base of the column and chlorine into the column between the ethylene feed point and the head of the column in the absence of light; (2) passing down the column a recycle liquor consisting of (i) 1,2-dichloroethane alone when 1,1,2-trichloroethane is required as product; or (ii) 1,2-dichloroethane and 1,1,2-trichloroethane when tetrachloroethanes are required as or in the product; the whole of the 1,2-dichloroethane in the products leaving the base of the column being recovered and recycled to the reaction column, and, in case (ii) above, a part or the whole of the 1,1,2-trichloroethane being similarly recovered and recycled; (3) maintaining the column at, at least 50‹ C. but not above the boiling point of the liquor fed in at the head of the column; (4) feeding into the head of the column additional 1,2-dichloroethane from a source outside the system, so that this, together with recycled liquor, gives a combined recycle liquor containing at least 5 mole per cent of 1,2-dichloroethane; (5) utilizing chlorine, in the presence of absence of oxygen, and such molar ratios of chlorine to ethylene that there is a net loss of 1,2-dichloroethane made in the system thus necessitating addition of 1,2 - dichloroethane from an external source, and so that 1 mole of 1,1,2-trichloroethane and/or tetrachloroethanes is produced per total of 1 mole of ethylene and 1,2-dichloroethane reacted; (6) withdrawing HCI from the condenser surmounting the column; and (7) recovering from the liquor leaving the base of the reaction column that portion of chlorinated ethanes which is not recycled to the reaction column and which is the desired product. To obtain a product consisting essentially of tetrachloroethanes when using chlorine free from oxygen the proportion of 1,2-dichloroethane in the combined recycle liquor should be greater than 20 mole per cent, e.g. 21À5 mole per cent, the remainder being 1,1,2-trichloroethane, with a molar ratio of chlorine to ethylene of 3-7 : 1. As the proportion of 1,2-dichloroethane in the combined recycle liquor is increased, the proportion of 1,1,2-trichloroethane in the product increases and may be obtained at any desired level accordingly. Unreacted ethylene may be recovered and re-used, or chlorinated or oxychlorinated, using, e.g. the HCl produced, to form 1,2- dichloroethane which may be fed to the column. If chlorine containing oxygen is used in the process of the invention, the ratios given above are adjusted.

Title: Improvements in or relating to rear-lamp tell-tale arrangements for vehicles
IPC: B60Q1/26
Filed: 1950-03-03
Abstract: 685,776. Lamp failure alarms and warning- devices. THOMPSON, J. E. March 5, 1951 [March 3, 1950], No. 5494/50, Class 118 (ii). A device to indicate the con dition of a vehicle rear lamp 10 comprises a pilot lamp 15 which, in series with a resist ance 14, is connected in paralle with the rear lamp 10 and in series with a common resist ance 11. The components are chosen such that the volt drop across resistance 11 ensures that the pilot lamp does not light properly when the rear lamp is functioning, but if the rear lamp fails the volt drop across resistance 11 decreases so that lamp 15 shines brightly. In a modification a further pilot lamp 20 is connected across the resistance 11 so that it shines brightly when the rear lamp is functioning but dims when the portion of circuit containing the rear lamp 10 is broken. A box-like mounting for the two lamps is described having a detachable cover with two apertures containing red and green filters for the lamps 15 and 20 respectively. The resistances 11 and 14 are accommodated inside the box which has a bracket and ring clip for clamping to the vehicle steering column, Fig. 6 (not shown).

Title: Improvements in or relating to the recovery of glycols from oxonation of mono-olefins
IPC: C07C29/141
Filed: 1953-02-27
Abstract: One molecule of a glycol is made from two or more molecules of a straight-chain a -olefine by treating the latter in a first stage with CO and H2 in the presence of not more than 1 per cent of a carboxylation catalyst (calculated as metal) based on the weight of olefine used at an elevated temperature and a pressure of 2000-10,000, preferably 4000-10,000, p.s.i.g., hydrogenating the carboxylation products in a second stage at an elevated temperature and pressure and in the presence of a hydrogenation catalyst and subsequently separating the glycol from the hydrogenation products. High molecular weight alcohols corresponding to the glycols are also obtained.  Preferably the olefine has not more than 7 carbon atoms per molecule butene-1, propene and heptene-1 being specified.  The final products may be worked up by separating the low molecular weight oxo alcohol by stripping at atmospheric pressure, distilling off the high molecular weight alcohol from the bottoms to leave the glycol. Alternatively the bottoms stripped of low and high molecular weight alcohols may be esterified, restripped to remove unchanged alcohols and simple esters to leave a bottoms consisting of glycol esters.  The glycol from butene-1 may be obtained in crystalline form on cooling the bottoms.  Iron and cobalt are specified carboxylation catalysts.  The glycols may be esterified with aliphatic acids of such molecular weights as to give esters having about 20 to 32 carbon atoms in their molecules which may be used as synthetic lubricants. The glycols may be used as perfume bases and their esters and ethers used in hydraulic fluids or light greases.  The glycol esters may also be used as plasticizers.  A greater yield of bottoms product is obtained if in the carboxylation stage the reaction time is long, the pressure is high and a cobalt catalyst concentration (calculated as metal) of about 0.1 per cent is used.  Examples are provided showing the preparation of glycols from butene-1 and propene using cobalt caboxylation catalysts and a Table is given illustrating the effect of increased pressure on yield of bottoms using butene-1, propene and butene-2, the latter being used for comparative purposes only.

Filed: 1953-03-02
Abstract: 725,962. Rotary plug valves. GROVE REGULATOR CO. March 2, 1953, No. 5794/53. Class 135. In a rotary plug valve having at least two passages such as 11 opening into the bore 16 for the valve plug, resilient sealing rings 23 of circular cross-section are disposed between the plug 17 and the body 10 to surround each of the passages 11, these sealing rings being accommodated in recesses 26 formed partly by sleeve insert sections 29 interposed between the plug and the body and anchored to the latter to prevent rotation therein. In the through-way valve shown in Fig. 2, each recess 26 is formed by an annular member 27 loosely fitting a counterbore in the passage 11, and a ported semi-cylindrical sleeve section 29, Fig. 3, mounted in the bore 16 about the valve plug 17. The members 27 and the sleeve sections 29 have lips 33, 34 respectively to retain the sealing rings whilst allowing part of the rings to make sealing contact with the plug. The ends of the plug are sealed by further resilient rings 24 of circular cross-section. These surround the plug and are arranged between the ends of the sleeve sections 29 and annular members 37 retained in the valve body by snap-in lock rings 39. In another embodiment, the invention is shown applied to a four-way rotary cylindrical valve of the duplex type. In a further modification, Fig. 8, suitable for very high pressures, the recesses 67 formed between the annular members 69 and the sleeve insert sections 68 are enlarged as at 72 by an inclined surface 73 on the section 68 so that line pressure applied inside the sealing ring 66 forces the ring into the recess extension 72 and out of sealing contact with the plug. When, however, pressure is applied from the valve body to the outer periphery of the ring, sealing contact is maintained. The ends of the plug are sealed by rings 76 similar to the rings 24 and the plug is further mounted in ball bearing assemblies 78 held in place by abutment rings 79 retained by snap-in lock rings 81. To relieve pressure trapped in the plug passage 64, a spring-loaded relief valve 86 is provided which connects the passage 64 with the fluid line through passages 89, 91.
