Patent GB-945778-A (GB)
Title: Manufacture of monovinylacetylene
IPC: C07C7/177
Filed: 1962-01-09
Abstract: A gaseous mixture of acetylene and monovinylacetylene is separated by countercurrent contact with a solution of acetylene in an organic solvent therefor to obtain (a) acetylene gas and (b) a solution of monovinylacetylene in the solvent.  The solvent is preferably water-miscible <PICT:0945778/C3/1> and may be dimethylformamide, acetone, acetonitrile, butyrolactone, dioxane, diethylacetamide and butyrolactam (pyrrolidone). The process is used in the production of monovinylacetylene from acetylene by contact with a cuprous chloride catalyst.  An acetylene-containing gas stream from an arc or pyrolysis process is contacted with a small amount of dimethylformamide to remove diacetylene and acetylene remaining in the gas is then dissolved by countercurrent contact with more dimethyl-formamide. The solution is introduced into an absorption column A (Fig. 1) into the bottom of which is introduced a mixture of acetylene and monovinylacetylene from reactor B. Acetylene from the top of absorber A passes to reactor B for conversion to monovinylacetylene. The solution from the bottom of absorber A containing monovinylacetylene and some acetylene is partially stripped in stripper C and the gas obtained containing some monovinylacetylene is recycled to absorber A.  The solution from stripper C is treated in still D to recover monovinylacetylene and dimethylformamide. Divinylacetylene formed together with the monovinylacetylene may be removed from the gas stream leaving reactor B by contact with a small amount of solvent before passing to absorber A. Alternatively, the divinylacetylene is removed from the bottoms from the still D either by operating the still under conditions such that no polymerization occurs and the divinylacetylene is stripped from the solvent or the still is operated to polymerize the divinylacetylene and polymer is kept at a low level in the circulating solvent by treating a bleed stream with water, filtering off the polymer and distillating the solvent.  The polymerization of acetylene is effected in solution with a cuprous chloride catalyst solubilized preferably with a hydrochloride of a primary or secondary amine in a liquid carboxylic acid amide, preferably dimethylformamide and, as a separate phase, a hydrocarbon or chlorinated hydrocarbon or an ether of ethylene glycol or diethylene glycol.

Title: Improvements in or relating to the production of gelatino silver halide photographicemulsions
Inventor: WOOD HENRY WALTER
IPC: G03C1/015
Filed: 1951-01-11
Abstract: Synthetic polypeptides are prepared by esterifying the g -carboxylic group of glutamic or a like amino acid, converting to the carbonic anhydride, any free reactive group being blocked before such anhydride formation, allowing to polymerize in pyridine solution, and removing any blocking groups that have been introduced, e.g. by hydrolysis.  The polypeptide may be polyglutamic acid, a copolymer of glutamic acid and another a -amino acid, or a corresponding compound in which aspartic acid is used.  An optically active compound or racemic mixture may be used.  The polymer may be dissolved in pyridine and precipitated with ether to free the polymer from polymers of lower molecular weight.  Copolymers may be prepared from 3 parts of g -methyl-glutamic anhydride and 1 or 2 parts of leucine anhydride, 1 or 2 parts of phenylalanine anhydride, or 1 part of o-acetyltyrosine or cystine anhydride.

Floor polishes can be formed from the above compositions by incorporating therein a levelling agent, e.g. alkali-soluble resins such as shellac, copolymers of maleic anhydride with styrene or methyl (or ethyl) vinyl ether, hydrolysis products of such copolymers and alkyl esters thereof, terpene-maleic anhydride condensation products, rosin adducts of polyesters derived from glycol or glycerol succinates, adipates or maleates, and phenol-formaldehyde condensates. The floor polishes may also include a natural or synthetic wax, and levelling, coalescing or plasticizing agents such as methyl Carbitol (" Carbitol " is a Registered Trade Mark), tributoxyethyl phosphate, 2-pyrrolidone and fluorinated hydrocarbons. The metal chelate (1) may be derived from Zn, Al, Ti, Zr, Ba, Ca, Mg, Sr, Pb, Co, Cr, Cu or Cd and from acids such as nitrilotriacetic acid, N-polycarboxylic acids of ethylene- or propylene-diamine which may also contain N-hydroxyphenyl or N-hydroxy-ethyl groups, diethylenetriaminepenta-acetic acid, diaminocyclohexane-tetraacetic acid and gluconic acid; the chelates may also include some alkali metal cations.

The copolymers are prepared from the monomers by emulsion polymerization in conventional manner, and the emulsion products can be neutralized with a volatile base and used to formulate the compositions of the invention. In examples, the copolymers used are 2-ethylhexyl acrylate/styrene/methyl methacrvlate/ methacrylic acid copolymer and 2-ethylhexyl acrylate / styrene / acrylonitrile / methacrylic acid copolymer.

Title: Method of purifying gas containing gassy mercury
Inventor: REIFU RINDAU
IPC: B01D53/34
Filed: 1980-01-07
Abstract: A method of highly efficiently separating preferably low contents of gaseous mercury from a gas mixture, where the gas mixture is caused to contact a solid sorbent consisting of powdered calcium hydroxide, which in an atmosphere containing hydrogen chloride is to a certain part converted to calcium chloride. The temperature of the gas mixture is between 350 DEG  K. and 550 DEG  K. The contact between the gas and the sorbent preferably takes place in a fluidized bed, whereafter the sorbent is separated in a dust separator. The method is suitable for use at the separation of mercury occurring in flue gases, for example from refuse incinerators or in mercury-containing gases from process industries. At experiments with flue gas from a refuse incinerator the mercury content was reduced from 200 to 5  mu g of gaseous mercury/cubic meter flue gas.
