Abstract
In the reaction of alkylene oxides with organic compounds containing a reactive hydrogen, e.g. an acid, amine, alcohol or phenol, up to 2% of an oxidation inhibitor or reducing agent is present in order to prevent or reduce undesired colouration. The reducing agent is colourless or has only a slight colour, and in the form of the oxidation product thereof, or in the form of an alkylene oxide addition product thereof has no or only a slight colour and does not form an insoluble precipitation. Specified are hydrazine hydrate, hydroxylamine, phosphorous and hypophosphoric acids, the salts of the compounds, the esters of the acids, or a mixture of two or more of these compounds, and hydroxylamine chlorohydrate, thiourea and sodium hyposulphite. Examples describe the reaction of (1) ethylene oxide (30 mols.) with stearic acid in the presence of hydrazine hydrate and hypophosphoric acid; (5) ethylene oxide (10 mols.) with stearylamine in the presence of hydrazine hydrate; (7) and (8) ethylene oxide (20 mols.) with oleylamine and coconut oil amine respectively in the presence of hydrazine hydrate; and also the preparation of polyethylene, polypropylene and polybutylene glycols.ALSO:In the reaction of alkylene oxides with organic compounds containing a reactive hydrogen e.g. an acid, amine, alcohol or phenol, up to 2% of an oxidation inhibitor or reducing agent is present in order to prevent or reduce undesired colouration.
