摘要： High molecular weight polyphenylene ethers are prepared from a monohydric phenol by an oxidative coupling reaction with oxygen in the presence of a catalyst complex obtained from a copper salt and an organic amine, and in the presence of a solvent, by a process in which the metal component of the catalyst is removed after the polymerization by adding one or more organic ammonium salts of the general formula ##STR1## where A.sup..crclbar. is an anion or polyanion of an organic carboxylic, sulfonic or phosphonic acid, R.sup.1 is hydrogen, R.sup.2 and R.sup.3 are each hydrogen, alkyl of 1 to 18 carbon atoms or aryl and R.sup.4 is alkyl of 1 to 18 carbon atoms or aryl.

摘要： Organic polyacids are prepared from monomeric monofunctional acids, such as acrylic acid or methacrylic acid and monomers without an acid group, with or without dicarboxylic acids or their anhydrides, by continuous free radical mass copolymerization under superatmospheric pressure at from 200.degree. to 400.degree. C., followed, if desired, by neutralization of the polyacids obtained. The polyacids obtained by the novel process are useful as phosphate substitutes and scale inhibitors in detergents and cleansers.

摘要： A coherent explosive gas phase in a gas/liquid reactor comprising a tubular body which is closed at the top and into which one or more jets of liquid which are fed from a liquid circulation and are directed downward, emerge from one or more nozzles located at the highest point of the reactor, and entrain a gas phase which is to be dispersed, introduce it into the liquid and finally produce complete dispersion of the gas, is avoided by a method wherein, before start-up of the liquid circulation, the inactive reactor is charged with an amount of liquid reactant such that a gas space corresponding to the subsequent gas hold-up of dispersed bubbles under operating conditions remains at the top of the reactor, this gas space is filled with a gas, at a pressure p.sub.1, which is inert under the reaction conditions, and the gaseous reactant is fed to the reactor only when, under the action of the liquid jet or jets, the inert gas has been dispersed into a hold-up of dispersed bubbles so that a coherent gas phase no longer exists.
