Patent GB-554125-A (GB)
Abstract: 554,125. Production of epoxide ethers. SHELL DEVELOPMENT CO. Sept. 18, 1941, No. 11973. Convention date, Sept. 30, 1940. [Class 2 (iii)] [Also in Group VI] Epoxide ethers are produced by re-acting a halohydrin ether, e.g. the monoether of a glycerine monohalohydrin, with a base or basic-acting compound at a temperature below 20‹ C., e.g. at -25‹C. to +10‹ C. and selectively extracting the epoxide ether as by using low boiling-point water-immiscible solvents, e.g. diethyl or di-isopropyl ether, isopentane, or benzene, and fractional distillation. The extraction may be effected in batches, intermittently, or, repeatedly using the same or different solvents. The halohydrin ethers, i.e. of the general formula R 1 -O-R 2  where in R 1  is a substituted or unsubstituted, saturated or unsaturated alkyl, aryl, aralkyl, or cyclo-aliphatic radical and R 2  is a substituted hydrocarbon radical containing at least one halogen and one hydroxy radical, e.g. to produce methyl-, ethyl-, allyl, or phenylglycidyl ethers. As basic compounds may be used metal oxides, hydroxides, carbonates, borates &c., preferably concentrated caustic alkali. In an example epichlorhydrin and allyl alcohol are re-acted at -15‹ C., with stannic chloride as catalyst, boiled, with refluxing, neutralized and distilled, sodium hydroxide slowly added to the remaining concentrate, at -2 to +2‹C. with agitation. After 5 hours the mixture was extracted six times, the extractions combined and frac tionated to yield 76.7 per cent. of allyl glycidyl ether of the formula The products may be used in the preparation of resins or as bactericides &c.

Abstract: 1449683 Solvent refining lubricating oil stocks EXXON RESEARCH & ENG CO 30 Nov 1973 [1 Dec 1972] 55628/73 Heading C5E Lubricating oil feedstocks are extracted with a solvent comprising a mixture of N-methyl-2- pyrrolidone, phenol and water to produce a raffinate, from which an upgraded lubricating oil is obtained, and an extract. The solvent suitably contains 0À5-6 wt. per cent water and 20-70 wt. per cent phenol. A feed 11, e.g. a distillate boiling above 550‹ F. or a deasphalted residue, is extracted in a tower 12 at 100-300‹ F. The raffinate phase 14 is passed into a separation zone 3 in which solvent is vaporized at 400-700‹ F. and 0-60 p.s.i.g. and a further portion of solvent is removed by the stripping gas 34; a minor portion 22 of the raffinate phase can be passed into the top of the zone 3 without being heated at 2. The extract phase 18 is freed of solvent in the zone 5 in a manner similar to the treatment of the raffinate. The stream 38 containing the vaporized solvent and stripping gases is cooled to produce steam 42 at 125-150 p.s.i.g. and then further cooled at 10. The cooled-material is separated at 7 into the liquid stream 64 and a vapour stream 50 which is cooled at 51 and separated into the liquid stream 58 and the recycle stripping gas 52. The stream 58 has a higher water content than the stream 64 and can be recycled to the bottom of the extraction tower 1. The raffinate 32 can be hydrofined using a catalyst of cobalt or nickel molybdate on alumina and then dewaxed.

Each welding device is provided with switching means enabling the device to be inoperative in a sequence of welding operations. Safety switching means are provided whereby any welding device not in operation is near short circuited to safeguard a welding operator. The scanning unit 19 basically comprises a free-running multivibrator and a binary counter to produce pulses which are used in the control system to sequence the welding operations, the control of both the pilot arc current, produced by withdrawing a stud from the workpiece, and of the welding current being effected by means of thyristors.
