    摘要: The invention relates to a method for production of polymeric hydroxylalkyl terminated polysulphides, whereby monomeric hydroxylalkyl terminated polysulphides are reacted with formaldehyde in the presence of an acid catalyst in the form of a solid acid, in particular, an acidic ion exchanger, in which the reaction water and optional added solvent and catalyst are separated off. The products are characterized by a very high uniformity (low polydispersity) and can advantageously be functionalized with subsequent reactions.

    摘要: Disclosed is a method for producing polymeric polysulfides containing terminal epoxy groups, according to which polysulfides containing terminal thiol groups are reacted with an excess of epichlorohydrin and alkaline lye, water is azeotropically distilled away with epichlorohydrin, the epichlorohydrin-containing epoxidized polysulfide solution is separated from the eliminated salt, the epichlorohydrin is distilled away, and the residue is optionally purified by means of thin film distillation. The reaction product is particularly suitable for the production of high-quality sealants, adhesives, and coatings. Said product has a high degree of purity and an extremely low chlorine content. The inventive method does not require any additional organic solvents and is very environmentally friendly.

    摘要: A process is provided for preparing polyhydroxycarboxylic acids by the selective oxidation of di-, tri-, oligo- and polysaccharides in an alkaline medium using an oxygenous gas in the presence of palladium on a carrier as catalyst and bismuth as promoter at a palladium concentration in the reaction mixture of at least about 40 mg/l and a molar ratio of bismuth to palladium in the range of from about 1:5 to about 1:40, in which process towards the end of the reaction, as soon as a strong increase is observed in the oxygen concentration in the liquid phase, the oxygen supply is reduced until it is not more than about 20 ppm. In this manner, virtually all of the polysaccharide added beforehand is converted into the desired end product without an unacceptably high concentration of bismuth in the end product.

    摘要: A process for the production of thiuram polysulfides substituted by aliphatic, araliphatic, cycloaliphatic aromatic and/or hydrocarbon radicals is disclosed. In this process, correspondingly substituted secondary amines are reacted with carbon disulfide and sulfur in a solvent at 0.degree. to 150.degree. C. in the presence of a tertiary amine, a metal-containing catalyst and oxygen or an oxygen-containing gas.By virtue of its high purity, the product obtained by this process may be used directly, i.e., without preceeding purification, for its intended purpose, for examples as a vulcanization accelerator or sulfur donor.This process is particularly desirable for the substantially quantitative yields and selectivities and also for its high economy arising from the reaction being carried out in a single stage without expensive auxiliaries and from the elimination of an additional purification step.

    摘要: The invention relates to a process for synthesizing alkylene bisdithiocarbamates or the ammonia adducts thereof as well as mixtures that can be synthesized thereby. The starting materials are carbon disulfide, ammonia, a diamine and a metal oxide, which may be manganese(II) oxide, or the hydrate or hydroxide thereof. The metal oxide, its hydrate or hydroxide thereof is allowed to react either with a mixture syntheiszed from an alkylenediamine, carbon disulfide and ammonia in water, or with an aqueous solution of the ammonium alkylene bisdithiocarbamate. The concentration of the individual starting materials both relative to each other and to water is of prime importances as to which compounds in particular are ultimately obtained.
