Patent GB-734403-A (GB)
Title: Improvements in or relating to the production of inorganic esters from mineral oils
Filed: 1950-10-24
Abstract: Esters and ester intermediates are made by contacting a mineral oil or mineral oil fraction with urea to form a solid urea-adduct, separating the urea adduct from the liquid phase, decomposing the adduct, recovering a fraction enriched in normal paraffins, oxidizing this fraction at elevated temperatures with a molecular oxygen-containing gas to form oxygen-containing compounds, including at least one hydroperoxide having, in the molecule the group >CH.OOH and thereafter reacting the hydroperoxide or a salt thereof with an oxide, halide or oxy-halide of arsenic, phosphorus or sulphur which is capable of conversion during the oxidation to a compound in which the said element is in a higher valency state than originally to yield products containing the said element in the acid radicle thereof.  Sulphur dioxide and phosphorus trichloride are preferred compounds.  The former yields alkyl hydrogen sulphates and the latter ROPOCl2, where R is an alkyl group.  The term ester intermediate is used to define compounds which on hydrolysis are converted to esters. The products may be reacted with a metal base to yield the corresponding salt.  The salts are detergents.  Preferably, petroleum fractions, e.g. kerosene and gas oil, are used. Preferably, sulphur is removed from the feed before oxidation. Feedstocks to the urea-adduct stage should boil from 200 DEG  to 350 DEG  C., preferably 250-290 DEG  C., when detergents are to be produced. Preferably, between 5 and 15 mols. of urea per mol. of normal paraffin is used and methanol is present during urea treatment. Adduction temperatures vary from 0-40 DEG  C., 20-25 DEG  C. being preferred.  Decomposition of the adduct may be achieved by treatment with a solvent for urea, e.g. methanol or water and/or by heating to about 60-100 DEG  C.  Thiourea may be used instead of urea in which case the residue from the adduction is used for oxidation.  Preferred oxidation temperatures are 110-180 DEG  C., especially 130-150 DEG C.  The preferred per pass conversion of hydrocarbon is between 5 and 30 per cent by weight.  Preferably, the peroxide concentration should be about half the maximum. Preferred conditions for the oxidation stage and for the reaction of the hydroperoxides are also described in copending Specifications 685,621 and 695,547.  In an example an aromatic free kerosene cut of B. Pt. 210-220 DEG  C. is treated with urea to give a normal paraffin fraction which is oxidized with air, the oxidate is reacted at 0-10 DEG  C. with SO3, excess SO2 is removed, and a quantity of the solid neutralized product is titrated with cetyl pyridinium bromide to determine its detergent activity.  A comparative experiment is provided in which the residue from the ureaadduction is oxidized and treated with SO2, it being shown that the product has less detergent activity.  Specifications 714,327 and 728,581, [Group III], also are referred to.

[Class 98 (ii).] In the production of an etching resist without any peripheral gap on the surface of a cylinder to be used for endless printing, a picture sheet (comprising the picture layer on a backing) which is to be mounted on the cylinder is formed with a non- adhesive leading edge beyond one of the edges that are to abut. This leading edge may be formed by incising the picture layer along the other abutting edge without cutting the backing and rendering a leading strip non-adhesive. The sheet is cut off along the other abutting edge and the leading edge inserted into the bight between the roller and a pressing device. The leading edge is detached when a length of the resist sheet is mounted on the periphery. Alternatively the sheet may be cut exactly to size along both abutting edges and a non-adhesive leading edge temporarily applied. To prevent penetration of water at the join of the abutting edges when the backing is being removed and the picture developed (if this is not done previously), the join is temporarily protected with a waterproof coating, and removed prior to the completion of the developing process and/or the removal of the backing.

Title: Improvements in or relating to the production of cellulose from wood, straw, or other fibrous plants
Inventor: KURZ HANS
IPC: D21C3/22
Filed: 1951-11-13
Abstract: Cellulose is obtained from wood, straw or other fibrous vegetable material by submitting the raw material to the action of an alkaline lye and of chlorine, these reagents being produced continuously by electrolysis of appropriate salt solutions previously added to the raw material, so that both reagents act in the nascent state on the cellulose material.  The treatment may be carried out at elevated temperature but is preferably effected at a temperature below 100 DEG C. and at atmospheric pressure.  The apparatus employed may comprise a container having an inlet <PICT:0717932/IV (a)/1> and outlet and arranged so that the fibrous material may be passed continuously therethrough, the container forming part of an electrolytic cell and being divided into two chambers by a diaphragm, one chamber having at least one cathode (or anode) for carrying out the electrolytic production of nascent alkaline lye (or chlorine), in intimate contact with the cellulose, and the other chamber being similarly equipped for the production of chlorine (or alkaline lye).  The salts employed are selected according to their ability to produce an alkaline lye or chlorine by electrolysis.  Sodium chloride, potassium chloride, alkaline-earth metal chlorides and alkali-metal and alkaline-earth metal sulphates and sulphites are specified.  As shown, the raw fibrous material is continuously fed through pipe 10 to a mixer 12 which is also supplied with common salt solution from a container 11. The slurry is passed into chamber 141, where caustic soda is continuously produced by electrolysis of the salt solution, the chamber being provided with a cathode 17.  The fibrous material is acted upon by the caustic soda and is passed through the chamber and out to an extracting unit 20, the extracted liquid being in part returned to the mixer 12 and in part to a washing vessel 28. The material passes to an opener 22, where the fibres are mechanically opened up, and then to the anode compartment 142, where chlorine is produced by electrolysis and acts in nascent state on the fibrous material.  The salt solution is continuously supplemented from a container 32.  The digested material is passed through outlet 24 to extractor 25 where most of the liquid is removed.  This liquid may be utilized in preparing a bleaching lye.  The cellulose fibres then pass to a multi-stage washer 28. In the first stage, the washing liquor is supplied through pipe 31 from the extractor 20, and the effluent passes through pipe 29 to evaporating, drying, and burning installations, so that the chemicals contained therein and the heat of combustion of the organic matter may be utilized.  In the second stage, washing liquid is supplied through pipe 35.
