Abstract: 580,877. Surface-treating rolled sections, ingots, &c. LINDE AIR PRODUCTS CO. April 28, 1945, No. 10760. Convention date, June 10, 1944. [Class 82 (ii) [Also in Group XXII] In removing scale or defects or a layer of surface metal from bodies such as hot rolled sections and ingots, high-frequency electric currents are induced into the body in substantially the depth of metal affected to heat said bodies to ignition temperature after which the surface thus treated may be subjected to the action of one or more oxidizing gas streams. An inductor 10, Fig. 1, is arranged in juxtaposition of the work B in a rolling mill line having a conveyor 14, and is connected by conductors 24, 26 to a source of high frequency power 28. The coil 10 is formed from copper tubes and is connected at 16, 18 to a water supply for cooling purposes ; the tubes may be telescoped to allow the coil to accommodate varying sizes of work. As the work passes through the coil its surfaces are heated to a depth depending on the frequency of the power source and are then acted on by streams of oxygen discharged from nozzles 32 in adjustable heads 30 of a desurfacing unit 12. In a modification for conditioning the top surface only of a metal slab a flat coil is arranged immediately above the work surface and may have a core for concentrating the magnetic lines of force. A water supply pipe is arranged between the inductor and the desurfacing unit to discharge a water jet across the top surface of the work in edgewise relation thereto, serving to remove the slag resulting from the metal removing operation and protect the inductor from thermo chemical reaction and the products of combustion and slag. In a further modification, Fig. 3, a heat resistant blade S is attached to an arm 40 pivoted on a support 44, and is pressed on to the work by a spring 48, the pressure being controlled by a stop screw 46 bearing on an abutment of the support. As the surfacing becomes plastic after passing under the inductor I the scraper blade removes the surface scale or may be set to remove metal to a required depth.

Title: Hydroxylation of vinylcyclohexene and the production thereby of esters, ethers and the like
IPC: C07C35/14
Filed: 1949-04-26
Abstract: The invention comprises hydroxy derivatives esters, and ethers thereof, and epoxides derived from 1-vinyl-cyclohexene-3, obtainable by the action on it of performic or peracetic acid in solution in the corresponding acid.  With one molar proportion of the peracid, the monoester of the 3 : 4 monoglycol is obtained, and may be hydrolysed to the mono-glycol, esterified, or etherified.  The mono-glycol and its esters and ethers give on a further such oxidation process the corresponding tetrol or ethers or esters thereof.  With 2 molar proportions of the peracid, a diester of the tetrol is obtained, which may be hydrolysed to the tetrol or its monoester, and esterified or etherified.  In presence of a lower aliphatic alcohol and mineral acid catalyst the above reactions produce the 3 : 4-hydroxy ether.  An inert solvent instead of mineral acid gives the epoxide.  Hydrogenation of the monoxide, monoglycol, or its esters or ethers gives ethyl cyclohexan epoxides, diols and corresponding derivatives.  In examples (1-3) reaction between 1-vinyl cyclohexene-3 and 1 mole of peracetic acid in presence of sulphuric acid or Zeokarb, or 1 mole of performic acid to give the corresponding vinylcyclohexane-3 : 4-diol monoesters, is described; (4 and 5) the monoester is directly hydrolysed to the 3 : 4-diol; (6-13) the diol and its monoesters are esterified with benzoic acetic, caproic, chloracetic and other acids to give di-esters or mixed di-esters; a number of other di-esters are listed (ex. 11); (14 and 15) reaction between vinyl cyclohexene and 1 mole of peracid in presence of ethanol gives the 3 : 4-diol monoethyl ether, and in chloroform, the 3 : 4-epoxide which is converted to the diol by hydrolysis with aqueous acid; (16-17) the 3 : 4 epoxide is converted to lauryl monoester, or ethyl monoether with acid or alcohol in presence of sulphuric acid; (18) the diol monoether is esterified with lauryl chloride, to give the etherester; (19-21) hydrogenation of the 3 : 4-diol, or its monoacetate with subsequent esterification with caprylyl chloride gives ethylcyclohexane 3 : 4-diol, and the mono and diesters thereof; (22) reaction between 1 vinyl-cyclohexene-3 with 2 moles of peracid gives a diacetate of 11 : 21 : 3 : 4-tetrahydroxyethylcyclohexane; (23) the 3 : 4-diol with 1 mole of peracid gives a tetrol monoacetate; (24) the diacetate of the vinylcyclohexene 3 : 4-diol reacts with excess of peracetic acid to give an ethyltetroltriacetate of cyclohexane in presence of sulphuric acid; (25 and 27) vinylcyclohexene reacts with 2 moles peracid in presence of tungsten trioxide to give a product which on hydrolysis gives the tetrahydroxy ethyl cyclohexane also produced from the 11-hydroxy-21 : 3 : 4-triacetoxy cyclohexane; (26) the latter is further acetylated to the tetraacetoxy-compound.  The products are used in the plastics industry for various purposes.  Specification 692,418, [Group IV (a)], is referred to.
