摘要： Olefins are converted to aldehydes and/or alcohols having one more carbon atom than the olefin by reacting the olefin with carbon monoxide and hydrogen in the presence of an in situ formed catalytic complex of a Group VIII metal, carbon monoxide and a trivalent ligand, the metal being introduced into the reaction zone in the form of a solution of a water-soluble inorganic salt dissolved in a solvent comprised of at least 40% by volume of a polyalkylene glycol, the polyalkylene glycol acting as a coupling agent preventing precipitation of the metal prior to formation of the catalyst complex.

摘要： In a process for hydroformylating an olefin in the presence of a catalyst comprising rhodium in complex combination with carbon monoxide and a triorganophosphorus ligand, progressive deactivation of the catalyst, as well as loss of the ligand species through by-product formation, are reduced by continuously stripping the liquid reaction medium to a degree such that the content of high-boiling organophosphorus by-products therein is maintained at a low level such that the ratio of phosphorus contained in said high-boiling by-products to phosphorus contained in the ligand present in the reaction medium does not exceed about 0.2.

摘要： Iodoisocyano, iodourea and oxazole modified 1,3 dioxep-5-ene ring monomers are synthesized and used in copolymerization reactions with trioxane to produce acetal copolymers with backbone functional groups. The invention also concerns processes for the production of acetal copolymers containing iodourea and oxazole functional groups from acetal copolymers with backbone double bonds.

摘要： Cationic copolymerization of trioxane and trimethylolpropane (TMP) formal or its ester derivatives yields acetal copolymers having pendant functional groups. The TMP formal or ester derivatives of TMP formal may therefore include functional groups selected from hydroxyl or ester moieties which are protected and thus survive the copolymerization with trioxane. These groups may then be present as functional reactive sites for the subsequent synthesis of block copolymers and/or to chemically bind modifiers to the acetal copolymer backbone, for example.

摘要： Cationic polymerization of trioxane and a mixture of ester derivatives of .alpha.,.alpha.- and .alpha.,.beta.-isomers of glycerol formal yields acetal terpolymers having pendant functional groups (i.e., ester groups, or hydroxyl groups obtained by hydrolyzing ester groups, pendent from the polymer's backbone). The glycerol formal monomers employed in this invention may include functional groups selected from ester moieties which are protected from, and thus survive, the polymerization process with trioxane. These groups may then be present as functional reactive sites for the subsequent synthesis of block polymers and/or to chemically bind modifiers to the acetal terpolymer backbone, for example.
