Title: Improvements in or relating to the production of ethylene chlorohydrin and acetylene
IPC: C07C7/148
Filed: 1953-06-10
Abstract: A saturated hydrocarbon is pyrolysed to produce a mixture containing substantial proportions of acetylene and ethylene, an acetylene-ethylene mixture is separated and reacted with chlorine in aqueous phase under chlor-hydrination conditions, ethylene chlorhydrin is recovered from the product, and a residual gas enriched in acetylene separated.  This may be reacted in a second stage with a reagent selectively reacting with acetylene. Normally gaseous or liquid saturated hydrocarbons such as natural gas or gasolines or higher boiling fractions, but preferably ethane, may be cracked at 1100-1600 DEG  C., if desired in presence of steam or other inert gas, to give acetylene and ethylene, preferably in equimolar proportions.  The product is separated, as by adsorption and desorption, into a saturated fraction, an acetylene-ethylene fraction, and a higher boiling fraction.  The chlorhydrination is effected at about 10-80 DEG  C. in one or more stages.  In place of chlorine per se, sodium or calcium hypochlorite may be used. Suitably, the hydrocarbons and chlorine are charged to the bottom of a water-flooded tower, water being introduced at the base and overflowing at the top with a content of up to 5 per cent hydrogen chloride and 10 per cent chlorhydrin. Exit gases may be recycled until the ethylene is substantially removed.  The residual acetylene is then reacted, suitably to an extent such that a tail gas suitable for recycle to the first stage with fresh feed, as in Specification 744,079, is obtained. The acetylene may be converted with hydrogen chloride to vinyl chloride as described in the above Specification; to vinyl acetate as in Specification 744,077; to dichlorethylene with hydrogen and air as in Specification 744,081; to acrylonitrile as in Specification 744,079; to acetylene alcohols by absorption in a suspension of potassium hydroxide as in Specification 744,082 and treatment with aldehydes or ketones as in Specification 744,079; to butynediol-1,4 with formaldehyde, to vinyl ethers with alcohols or to styrene with benzene, as described in the same Specification. Examples illustrate the chlorhydrination with water and chlorine, and conversion of the acetylene-enriched residual gas to vinyl chloride, dichlorethylene, vinyl acetate and butynediol-1,4, also its absorption in a suspension of potassium hydroxide in xylene followed by heating to give substantially pure acetylene.

Title: Improvements in or relating to the production of hydrogen peroxide
IPC: C01B15/023
Filed: 1958-05-20
Abstract: In the production of hydrogen peroxide by a cyclic process involving alternate reduction and reoxidation of one or more anthraquinones in an organic solvent medium with degradation of the solution, the degraded solution is treated in the reduced state with an aqueous solution of an alkali metal hydroxide, e.g. sodium or potassium hydroxide, so as to extract anthrahydroquinone therefrom, and the anthrahydroquinone, as such or as anthraquinone, is recovered from the aqueous extract and dissolved in solvent recovered from the residual degraded solution.  The reduction and extraction may each be carried out in a number of stages.  Reduction is preferably substantially complete.  The degraded working solution from the hydrogenation stage, which is usually 40-70% hydrogenated, may be first extracted and then further hydrogenated and extracted, or it may be first further hydrogenated and then extracted.  The degraded solution may be treated, before or in an intermediate stage of the extraction treatment, so as to convert regenerable degraded material into anthraquinone.  Regeneration may be effected by heating the solution at a temperature of at least 55 DEG  C. in the presence of alumina or magnesia, or heating the solution at a temperature of 125-200 DEG  C. in the presence of oxygen, and then reducing the anthraquinone thereby formed.  Anthraquinone as such or as anthrahydroquinone may be recovered by precipitation from the aqueous extract, e.g. by acidification or oxidation with air, in the presence of solvent medium, which may be recovered from the residual degraded solution by distillation.  The alkali metal hydroxide concentration of the extracting solution may be 1-30%, preferably 10-20%.  The temperature of extraction may be 10-75 DEG  C.  Reduction before extraction may be effected by hydrogenation in the presence of Raney nickel or a supported palladium or platinum catalyst, or by zinc and aqueous sulphuric acid or sodium hydroxide.  All of the working solution may be periodically treated, or a portion thereof may be continuously or intermittently bled off, treated, and then returned to the main working solution.  The anthraquinone may be 2-tert.-butyl anthraquinone.  The solvent medium may be a mixture of a -methylnaphthalene and diisobutylcarbinol.  Examples are given. Specification 798,237 is referred to.

In a nuclear reactor the leakage of contaminated coolant gas is prevented. Coolant gas is passed from a supply tank to the reactor chamber through valves which are automatically controlled in accordance with the pressure difference between the reactor and supply tank. If the reactor pressure becomes greater than that in the tank, due to a leak in the latter, the valves are automatically closed. Any leakage into the supply tank, of radioactive gas from the reactor, through the closed valves, is slow enough to permit decay of the radioactivity of the safety level.
