Abstract: Unsaturated organic compounds are brominated with a quaternary ammonium tribromide or a quaternary phosphonium tribromide, especially when the bromination is conducted in a chlorinated solvent. A quaternary ammonium or quaternary phosphonium monobromide salt is produced in the reaction, together with some amount of quaternary ammonium or quaternary phosphonium monochloride salt. The monochloride salt is converted to the corresponding quaternary ammonium monobromide salt by reacting it with a source of bromide ions. The monobromide salt is then reacted with bromine to regenerate the quaternary ammonium or phosphonium tribromide, which is recycled into the bromination reaction. This process reduces the amount of chlorine that is incorporated into the brominated product.

Abstract: A water redispersible polymer powder may be produced by drying an aqueous mixture of a water insoluble film-forming polymer and a colloidal stabilizer comprising a chelating agent to obtain a water redispersible polymer powder, where the amount of chelating agent is at least 0.1% by weight, preferably at least 1% by weight, most preferably at least 3% by weight, based upon the weight of the water insoluble film-forming polymer. Dispersions or polymer compositions containing a chelating agent as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. The chelating agents are stable at high pH and so high pH spray dryable compositions containing them as a colloidal stabilizer may sit or be stored for prolonged periods of time prior to spray drying without loss of effectiveness of the colloidal stabilizer.

Two or more reactors include a number of reaction tubes each having a first surface defining a first side and a second surface defining a second of each of the tubes side are provided. A catalyst for catalytic oxidation of olefins can be located on the first side of the number of reaction tubes is included. A common supply line supplies inlets to each reactor that provide a mixture comprising olefins and oxygen to the catalyst. Product outlet streams of each reactor receive at least the oxidized olefin product and are joined to a single product stream. Coolant fluid passes through the reactors to remove heat from the number of reaction tubes and flows into a single coolant drum connected to the two or more reactors. The single coolant drum receives the coolant fluid from a number of coolant fluid outlet streams of each of the reactors.
