Title: Improvements in and relating to the condensation of alcohols
IPC: C07C29/34
Filed: 1948-08-12
Abstract: Primary or secondary aliphatic alcohols containing 3 to 8 carbon atoms in the molecule and a CH2 group next to the hydroxylated carbon atom are converted into alcohols containing double the number of carbon atoms by heating under pressure at a temperature between 270 DEG  and 300 DEG  C., e.g. 290-300 DEG  C., with an alkali metal or an alkali metal hydroxide in the presence of boric anhydride or an alkyl borate.  Alkyl borates used are generally those corresponding to the alcohol to be condensed.  The process leads to the suppression of acids corresponding to the starting alcohol so that less alkali is required as compared with the usual Guerbet condensations.  Potassium hydroxide may be used without prior dehydration to the alkoxide, particularly when an alkyl borate is present and is also specific to this type of reaction for it cannot be replaced by sodium hydroxide unless the latter is dehydrated.  The products are isolated by the addition of water and fractionation of the resulting organic layer. Boron compounds may be recovered from the aqueous layer and re-used. Quantities of boric anhydride present when tech. potassium hydroxide is used to condense butyl alcohol range from 0.25-0.5 mol. proportions and when metallic sodium is used 0.6 mol. proportions of butyl borate are used.  With increase of boron compound the formation of butyric acid decreases and when nil only half the quantity of alkali used in prior processes is required.  In Examples (1) and (2) n-butanol is reacted in an autoclave at 290 DEG  C. for five hours with tech. KOH and B2O3 to yield 2-ethylhexanol-1 also made in (3) and (4) by autoclaving n-butanol and metallic sodium for 5 hours at 290 DEG  C. with butyl borate and similarly in (5) and (6) using tech. KOH in place of Na, and in (7) 2-propyl-heptanol-1 is made by autoclaving n-amyl alcohol for 5 hours at 290 DEG  C. with tech. KOH and amyl borate.  The Provisional Specification is not limited to the use of alcohols containing 3-8 carbon atoms and refers generally to the use of all boron compounds those specified, other than those of the complete Specification, being alkali borates, e.g. potassium metaborate.

IPC: C07F7/18
Filed: 1957-07-10
Abstract: An organosilicon compound having attached to at least one Si atom by a Si-C linkage at least one organic radical containing at least one epoxide group, any remaining valencies being satisfied by hydrocarbon, halohydrocarbon, hydrocarbonoxy, halohydrocarbonoxy or hydroxyl radicals, or hydrogen or oxygen atoms, is made by heating a mixture of an unsaturated organic compound containing at least one epoxy group and a silicon compound containing at least one SiH group. The products are either silanes of the formul  AxSiX4-x and AmRnSiX4-n-m or siloxane polymers or copolymers of the formula AmRbSiO4-m-b, wherein R is hydrogen, a hydrocarbon or halogenated hydrocarbon radical, X is a hydrocarbonoxy or hydroxyl radical, A is an epoxy or epoxidized radical, x is 1 to 4, m and n are each 1 to 3 and b is 0 to 2. The compounds may be cured by reacting them with conventional epoxide curing catalysts.  In typical examples: (1) allylglycidyl ether was reacted with a mixture of tetramethyldisiloxane and toluene containing a diethyleneglycoldimethylether solution of chloroplatinic acid to yield on fractionation <FORM:0834326/IV (a)/1> and <FORM:0834326/IV (a)/2> and (2) vinylcyclohexenemonoepoxide was similarly reacted with [CH3.H.SiO]5 to give <FORM:0834326/IV (a)/3> which cured with m-phenylenediamine into a hard, tough, heat-stable resin.  Uses.-The compounds can be formed into cured mouldings, castings and films; used for coating metals and glass; used as adhesives; incorporated into epoxy, alkyd, aminoplast and polyamide resins and other siloxanes containing functional groups, these modified products being useful as lubricants, coating compositions, casting resins and paints; and can be used as intermediates in making organic-modified silicon compounds by reaction of the epoxide group, e.g. with water, HCl, HNO3, carboxylic acids, NH3 and amines, HCN, Na2SO3, phenols, Grignard reagents, alcohols, aldehydes and ketones, H2S, H3PO4 and with mercaptans, to yield respectively a glycol, a chlorohydrin, a hydroxynitrate ester, hydroxy esters, hydroxyl amine, cyanohydrins, hydroxy sodium sulphonate, hydroxy phenyl esters, hydroxy alcohols, hydroxy ethers, acetals, hydroxy thiols, hydroxy phosphate esters and hydroxy thioethers.

Abstract: New dyestuffs are made by treating compounds of the anthraquinone series and related types as hereinafter defined which carry one or more chloromethyl or bromomethyl groups by known methods for replacing the chlorine or bromine atoms of the chloromethyl or bromomethyl groups by quaternary ammonium groups. The compounds of the anthraquinone series and related types referred to in this Specification are the coloured compounds which may be represented by the formula <FORM:0613982/IV (c)/1> wherein A and B may be the same or different and may be carbon, nitrogen or sulphur atoms which form part of one or more ring systems condensed with one or both of the phenylene nuclei X and Y, or may be oxygen atoms, and wherein the phenylene nuclei X and Y may carry further substituents other than sulphonic or carboxylic acid grops, or may carry rings condensed with two adjacent carbon atoms of X or Y, provided than when the number of aromatic and quinonoid rings in the condensed ring systems is less than 6 then a heterocyclic ring which forms part of the condensed ring system must carry at least one pendent aryl nucleus free from sulphonic or carboxylic acid groups connected directly, or X or Y or any of the condensed rings must carry at least one pendent aryl nucleus (free from sulphonic or carboxylic acid groups) connected through an -O-, -S-, -NH, -NH-CO- or -CO-NH- linkage. Examples of starting materials which may be used in this invention include mono- and bis(chloromethyl) - acedianthrone, bis - (chloromethyl) - dibenzanthrone, bis - (chloromethyl)-isodibenzanthrone, chloromethyl-indanthrone, the chloromethyl derivative of 8 : 17-di-p-toluidinoindanthrone, the bis-chloromethyl derivative of 2 : 8-diphenyl-11 : 21(N) : 51 : 61(N)-anthraquinonedithiazole and bis - (chloromethyl)-1 : 4-dianilino-, 1 : 4-di-p-toluidino-and 1 : 4-di-m-xylidino-anthraquinone, bis-(chloromethyl)-perylene-3 : 4 : 9 : 10-tetracarboxy-di-)phenylimide).  The starting materials for use in this invention may be made by reacting the compounds of the anthraquinone series and related types with dichloro- or dibromodimethyl ether in the presence of a condensing agent such as for example sulphuric acid.  An example of suitable methods is heating the chloro- or bromo-methyl derivative with a tertiary amine, for example, pyridine, tri-ethylamine, dimethylcyclohexylamine.  In examples, pyridine is reacted with the chlormethyl derivatives of (1) dibenzanthrone; (2) isodibenzanthrone; (3) acedianthrone; (4) 8.17 - di - p - toluidinoindanthrone; (5) 1.4-dianilinoanthraquinone; (6) perylene-3.4.9.10-tetracarboxy-di-(phenylimide); (7) 1.4-bis-(m - chlormethylbenzoylamino) anthraquinone.

[Class 39 (i)] [See also Group XX] An X-ray tube, for irradiating cavities of the body, is mounted partly within a flexible high tension cable, so that the mechanical connection between the tube and cable is effected without additional insulating terminal parts. The projecting part of the tube is about the same diameter as the cable. The tube comprises a cylindrical metal part 1 provided at its end with a glass window 5, and a funnel-shaped glass extension 2. The anode 7, which may be formed of tungsten, is supported by a metal tube 8, connected by a glass tube 9 covered with a thin metal coating, to a metal tube 6 secured to the end of the glass funnel. The glass portion 9 prevents transmission of heat to the cable and its covering acts as a protective resistance.
