Abstract: The invention relates to polymeric soluble hydrogenation catalysts in which a metal of the eighth subgroup of the periodic system is bound by covalent and/or secondary valent bond to a soluble polymer. The hydrogenation catalysts are produced by reacting the selected polymer having a functional group with a metal, metal complex or metal salt wherein the metal is of the eighth subgroup of the periodic table, the reaction taking place in aqueous solution or in solution in an organic solvent. The catalysts of the invention can be used for the catalytic hydrogenation of organic compounds in solution.

Abstract: A process for producing 2,3-dimercaptopropane-1-sulfonic acid or its salts useful as an antidote to toxic metal salt poisoning comprising reacting an allyl bromide with sodium sulfite in aqueous medium at a temperature from 50 to 100 degrees C. to produce sodium-2-propene-1-sulfonate, brominating the 2-propene-1-sulfonate, eliminating excess bromine by adding sodium sulfite, adjusting the Ph to 4.5 with sodium hydroxide, reacting the brominated compound with sodium hydrogen sulfide in an alkaline medium to produce sodium-2,3-dimercaptopropane-1-sulfonate, precipitating the raw product as a lead salt or mercury, cadmium, tin, copper, nickel, cobalt or zinc complex, suspending the precipitated product in methanol and reacting it with gaseous hydrogen sulfide, adjusting the Ph of the solution with a solid bicarbonate selected from the group consisting of sodium bicarbonate, ammonium bicarbonate and potassium bicarbonate to a Ph of 4.

Abstract: Soluble catalysts for polymerizations are provided which are formed from an organic polymeric material containing at least one functional group bound to a metal, metal ion or metal complex. These catalysts can be used to promote all types of polymerizations, such as of vinyl compounds, etc.These catalysts are produced by reacting the basic polymer with a metal salt or metal complex, particularly of a metal of the third through the eighth subgroups of the periodic table or of the third and fourth main groups of the periodic table, the catalyst being formed by exchange with the metal or metal ion being bound to the polymer.

Abstract: This invention relates to the production of penicillamine and acid addition salts of penicillamine through the production from penilloic acid or penicilloic acid formed by hydrolytic decomposition of a penicillin of penicillamine-mercuric-mercaptide which can be easily decomposed by means of hydrogen sulfide to penicillamine. The penicillamine-mercuric-mercaptide is formed as a crystalline precipitate by reaction of the penicilloic acid or penilloic acid with a mercuric salt in a ratio of 1:0.5 in a medium of a water miscible organic solvent and the precipitated penicillamine-mercuric-mercaptide after separation from the reaction medium is decomposed to the penicillamine.
