Title: Improvements in the electroplating of precious metals on to articles made of baser metals
IPC: C25D5/12
Filed: 1966-10-13
Abstract: A tarnish- and corrosion-resistant coating is provided by a layer of chromium with a coating of a precious metal supported on the chromium layer and adhered to a depassivated surface thereof. The chromium coating may be depassivated by subjecting it to a cathodizing current in an acid bath, e.g. it may be treated in 5%-10% hydrochloric acid or sulphuric acid at room temperature for 5-30 minutes with a cathode current of 30-40 amps/square foot. Phosphoric and acetic acids may also be used for depassivation. The surface is then rinsed in a weak acid bath, e.g. 0.01-1% hydrochloric or sulphuric acid and then electro-plated with the precious metal which may be gold, platinum, palladium or rhodium. Specific acid gold cyanide bath compositions are referred to for plating with gold.  These baths may also contain salts of base metals such as iron, nickel, cobalt, tin, cadmium or zinc to produce a gold alloy coat.  For plating the platinum group metal baths may be prepared from iodo complexes containing excess of iodides of alkali metals, ammonium or magnesium, repassivation of the chromium by liberated iodine being avoided by placing the anode in a porous compartment of unglazed porcelain or fritted glass, using acid or alkaline anolytes.  The substrate may be coated first with copper, then with nickel, an adherent chromium coating being applied to the nickel surface.

Gas mixtures are separated by absorption of one or more components of the mixture in a suitable liquid absorbent in a multistage process, gas and liquid flowing in cocurrent within each stage but countercurrent overall. Thus, in stage I, the gas stream (broken line) and liquid stream (solid line) pass in cocurrent up duct 15, unabsorbed gas passing from stage I successively to stages II and III to contact progressively burner absorbent, product gas leaving at 12. The richest absorbent leaves at 13, suitably for regeneration and recycling to stage III. If preferred, the stages may be mounted one above the other (see Fig. 2, not shown), and duct 15 may be filled with suitable packings. In examples, an ethanolamine/dimethyl sulphoxide absorbent is used to absorb CO 2  from a mixture thereof with H 2 ; and an ethanolamine/ N-methyl pyrrolidone mixture is used to absorb CO 2  from a mixture thereof with N 2 . In both cases, the absorbent is regenerated by driving off the CO 2  heating. Reference is also made to the absorption of various other gases using diverse solvents.

Title: A method for the production of vitamin a and esters thereof
Filed: 1955-12-07
Abstract: The invention comprises Vitamin A2 acetate and a process for the production of Vitamin A2 esters by condensing 4-[21,61,61-trimethyl -cyclohexadiene - (11,31) - yl - (11)] - 2 - methyl - buten - (2) - al - (1) with 1 - hydroxy - 3 - methylpenten - (2) - ine - (4) in a metallo - organic reaction, partially hydrogenating the triple bond of the 1,6-dihydroxy-3,7-dimethyl-9-[21,61,61 -trimethyl - cyclohexadiene - (11,31) - yl - (11)]-nonadien-(2,7)-ine-(4) so obtained, esterifying the resulting nonatriene by treatment with an acylating agent and dehydrating or splitting off acid from (while simultaneously effecting allyl rearrangement) the ester so obtained. The reduction and esterification stages may be effected in reverse order.  In the metalloorganic reaction there may be used an alkali compound, e.g. lithium or phenyl lithium, or alkali magnesium halide, e.g. ethyl magnesium bromide.  The reduction may be effected by catalytic hydrogenation, e.g. in the presence of palladium, or by means of lithium aluminium hydride. Esterification may be effected with an acid chloride or anhydride. The final dehydration or splitting off of acid may be effected with phosphorus oxychloride, pyridine hydrochloride or by boiling with a strong organic acid, e.g. phthalic acid.  Alternatively, splitting off of acid may be effected by treatment with aqueous hydrohalic acid and treating the reaction product with water or a basic compound.  The Vitamin A2 esters thus obtained may be saponified to free Vitamin A2 and reesterified.  In examples 4-[21,61,61-trimethyl -cyclohexadiene - (11,31) - yl - (11)] - 2 - methyl - buten - (2) - al - (1) is condensed with 1-hydroxy - 3 - methyl - penten - (2) - ine - (4) to produce 1,6 - dihydroxy - 3,7 - dimethyl - 9 - [21,61, 61 - trimethyl - cyclohexadiene - (11,31) - yl-(1)1]-nonadiene-2,7-ine-4, which compound is hydrogenated to produce the corresponding (2,4,7)-nonatriene, which compound is esterified to produce 1-acetoxy-6-hydroxy- and 1,6-diacetoxy - 3,7 - dimethyl - 9 - [21,61,61 - trimethyl-cyclohexadiene (11,31) - yl - (11)] - nonatriene - (2,4,7) which compounds are dehydrated and deacetylated respectively.  Starting compound.  4 - [21,61,61 - Trimethyl -cyclohexadiene - (11,31) - yl - (11)] - 2 - methyl - buten - (2) - al - (1) is obtained by brominating 4 - [21,61,61 - trimethyl - cyclohexen - (11) - yl - (11)] 2 - methyl - buten - (2) - al - (1), splitting HBr from the product to form 4-[21,61,61-trimethyl - cyclohex - 21 - ylidene - (11)] 2 - methylbuten - (2) - al - (1), which compound is treated with isopropenyl acetate to produce 4-[21,61,61-trimethyl - cyclohexadiene - (11,31) - yl - (11)] - 2 - methyl - 1 - acetoxy - butadiene - (1,3) which is hydrolysed.

Patent GB-458626-A (GB)
Title: A process for the production of carbonyl compounds
IPC: C07C45/30
Filed: 1935-12-24
Abstract: Carbonyl compounds, i.e. aldehydes or ketones, are obtained by reacting an unsaturated non-halogenated compound possessing a double linkage between two carbon atoms, one, but only one, of which is tertiary, with chlorine and water at a temperature substantially above 100 DEG  C.  The process may be conducted in the liquid phase at elevated pressure with the water present in substantial excess. Suitable temperatures are 140--250 DEG  C. Preferably, the carbonyl compound is removed from the reaction mixture as soon as it is formed therein, e.g. by distillation. Preferably, the solution is maintained acid, e.g. by maintaining a concentration of hydrogen chloride in the reaction mixture of about 0,5 to 2,5 N.  Other mineral acids or acid salts may also be added for this purpose.  Undesirable excess acidity may be prevented from accumulating in the reaction mixture by continuously or intermittently replacing portion of the mixture by water or by carrying out the reaction in the presence of a metal carbonate, e.g. calcium carbonate.  The initial unsaturated compounds which may be employed include tertiary butylene, the tertiary amylenes, hexylenes, heplylenes, octylenes, &c., and their unsaturated polymers, homologues and non-halogenated substitution products.  The unsaturated compound may comprise an iso unsaturated alkyl chain which may or may not be linked to a cyclic radical or the chain may comprise part of an alicyclic structure.  The olefinic compounds may be employed in the pure state or in admixture with each other or with inert substances. Such mixtures may be obtained by the pyrogenesis or cracking of petroleum oil &c. or by the destructive distillation of coal, peat, pitches, asphalts, &c.  According to examples, (1) 2-methyl-butene-2 is introduced with chlorine in the molecular ratio of 1 : 1 to 1 : 0 through separate conduits into a large volume of water maintained in the liquid phase at 160 DEG  C., methyl isopropyl ketone being obtained and distilled from the reaction mixture substantially as soon as it is formed therein; (2) similarly isobutylene and chlorine are introduced into water in a pressure still kept at a temperature of 155 DEG  C. and a pressure of 75 pounds per square inch, isobutyraldehyde being obtained.  The products may be recovered from the condensed distillate by allowing it to stratify and separating, drying, and fractionating the non-aqueous layer.  Specification 426,519, [Group IV], is referred to.  The Specification as open to inspection under Sect. 91 describes also the employment of halogens other than chlorine and the conduction of the reaction set forth in example 2 above at a temperature of about 100 DEG  C.  This subject-matter does not appear in the Specification as accepted.
