Patent GB-713120-A (GB)
Title: A new alkyl-aromatic halogen-containing phosphorus compound
Inventor: ZENFTMAN HENRYK
IPC: C07F9/146
Filed: 1952-01-25
Abstract: The invention relates to p-tert.-octyl-phenoxy phosphorus dichloride which may be prepared by reacting p-tert.-octyl-phenol with more than one molar proportion of phosphorus trichloride, removing the hydrogen chloride evolved and distilling at the end of the reaction to remove unconsumed phosphorus trichloride.  The octyl phenoxy phosphorus dichloride may be reacted with alcohols under anhydrous conditions yielding the mono- or di-alcohol ester according to the proportions used.  These esters may be converted into the corresponding thio-phosphoric acid esters by heating with sulphur.  The latter esters may also be formed by heating the octyl-phenoxy phosphorus dichloride with sulphur thereby forming the thio derivative which may then be reacted with an alcohol.  In an example, p-tert.-octyl-phenol in powder form is slowly added to 3 mols. of PCl3 at room temperature, and the product, after evolution of hydrogen chloride has ceased, is distilled to remove excess PCl3 and the residue distilled under reduced pressure to recover the desired octyl-phenoxy phosphorus dichloride; the latter is heated with sulphur at 180-200 DEG  C. to yield the thio derivative or with ethyl alcohol in ethereal solution to yield diethyl octyl-phenyl phosphite which is reacted with sulphur to form the corresponding thiophosphate. Reference is made to the formation of like esters in which instead of the ethyl groups, other alkyl groups and/or aryl groups may be present.

Patent GB-799753-A (GB)
Title: Process for the production of polyhydric compounds
IPC: C07C31/18
Filed: 1955-01-27
Abstract: Polyhydric compounds are prepared by subjecting an organic compound having an olefinic double bond to hydroxylation with an aqueous solution of hydrogen peroxide at a temperature not less than 40 DEG C. in the presence of isopropyl formate as a reaction medium, decomposing any residual hydrogen peroxide, for example by means of a roughened platinum sheet, separating unchanged isopropyl formate and at least part of the water from the reaction product and subjecting the residue to treatment for the alcoholysis (with a C1 to C4 saturated aliphatic alcohol) or saponification of any polyhydric compound-formic ester formed in a side-reaction during the hydroxylation.  The hydroxylation may be effected with a stoichiometric quantity of concentrated H2O2 in the presence of about 2-3 mols. of isopropyl formate per mol. of unsaturated organic compound. Temperatures not exceeding 100 DEG  C., e.g. reflux temperatures, are preferred.  Pressure vessels are used when hydroxylating low boiling or gaseous unsaturated compounds.  The removal of unchanged isopropyl formate is preferably achieved by distillation whereby 10-15 per cent of the original water present is retained in the residue.  This water facilitates alcoholysis of the formic acid-ester by-products which may be effected by means of isopropyl alcohol using as a catalyst hydrofluoric, hydrobromic, hydrochloric or maleic acid.  The resulting residue of polyhydric compound free from esters may be further purified by distillation or by dissolution in hot water or a lower alcohol, followed by removal of insoluble impurities, decolorization and fractionation to remove the solvent.  Examples describe the treatment of (1) a C7 fraction of paraffins and olefinic hydrocarbons B.R. 95-99 DEG  C., obtained by hydrogenation of carbon monoxide, yielding a mixture of heptane-diol and its diformic acid ester, which mixture is subjected to alcoholysis as above described; (2) a decene, obtained by catalytic cracking of petroleum, yielding a mixture of decane diol and its diformate ester which is alcoholysed as in (1); (3) tricyclodecene-4, produced according to Specification 779,241, yielding 4:5-dihydroxy-tricyclodecane and its formic acid ester, the mixture being thereafter saponified with aqueous NaOH; (4) 8-hydroxy-tricyclodecene, obtained as described in Specification 775,298, yielding a mixture of 4:5:8-trihydroxy-tricyclodecane and its triformate, which is alcoholysed as above described; (5) dicyclopentadiene, yielding a mixture of 4:5:8:9-tetrahydroxy-tricyclo decane and its formate ester which is alcoholysed as above and the tetrol is extracted from the alcoholysate with water leaving an insoluble viscous residue having an ester number of 30 and a hydroxyl number of 50; (6) allyl alcohol, yielding glycerol and its formate ester, the mixture being alcoholysed as described above; and (7) phenyl-dimethyl pyrazolone, yielding the corresponding dihydroxy compound and its formate ester which is alcoholysed as above.
Patent GB-509790-A (GB)
Title: A process for dyeing and printing mixtures of cotton and regenerated cellulose
IPC: D06P1/28
Filed: 1938-01-27
Abstract: 509,790. Dyeing textiles. JOHNSON. G. W. (I. G. Farbenindustrie Akt.-Ges.). Jan. 27, 1938, No. 2654. [Classes 2 (iii) and 15 (ii)] Mixtures of cotton and regenerated cellulose are dyed or printed green-blue shades with sulphuric acid esters of leuco-3.3<1>-dibrom-1.2. 2<1>, 1<1>-anthraquinone-dihydroazine in the usual manner. The said sulphuric esters are obtained by converting 2 - acylamino - 3 - bromanthraquinones to their leuco-sulphuric esters, splitting off the acyl group by means of alkali, and oxidizing the sulphuric ester of the 2-amino- 3-bromanthraquinone thus formed in presence of alkali, with oxidising agents such as higher oxides of lead, e.g., lead dioxide, alkali hypochlorites, permanganates or ferricyanides. By treatment of the ester salts with oxidizing agents in acid solution leuco compounds poorer in ester groups but having increased affinity for fibres may be obtained. In examples, (1) a fabric consisting of equal parts of cotton and viscose artificial silk is treated with a solution of sodium sulphate and the potassium salt of the sulphuric ester of leuco - 3.3' - dibrom - 1.2.2<1>.1<1> - anthraquinonedihydroazine. and the dyeing developed with sodium nitrate and sulphuric acid : (2) a fabric consisting of cotton and regenerated cellulose, e.g., viscose artificial silk is printed with a paste containing starch tragacanth, the above ester salt, ammonium thiocyanate, sodium chlorate, ammonia, thiodiglycol and ammonium vanadate, dried and steamed. The 2 - acylamino - 3 - bromanthraquinones are made by treating 2-amino-3-bromanthraquinone with acylating agents, e.g., aliphatic acids and their chlorides and anhydrides such as acetyl chloride, propionyl chloride, acetic anhydride, phosgene, chlorocarbonic acid esters, and aromatic carboxylic acids and their halides and anhydrides such as benzoyl chloride. The 2 - acylamino - 3 - bromanthraquinone leuco sulphuric esters are prepared by reacting the parent anthraquinone with a metal such as iron in presence of pyridine or similar bases and sulphur trioxide or an agent yielding the same such as chlorsulphonic acid or its sodium salt or methyl or ethyl ester or oleum. They may also be prepared by treating a 2 - acylamino-3-bromanthrahydroquinone with sulphur trioxide in, for example, chlorbenzene and dimethylaniline. 2-acylamino - 3 - bromanthrahydroquinones are prepared by catalytic hydrogenation of 2- acylamino-3-bromanthraquinones ; the preparation of 2-acetamino-3-bromanthrahydroquinone is described by hydrogenation of 2-acetamino- 3-bromanthraquinone in presence of chlorbenzene, dimethylaniline and a nickel catalyst.
