| titleOfInvention | Modified normally liquid, water-soluble polyoxyalkylene polyamines |
| abstract | In accordance with the process of the present invention normally liquid, water-soluble poly(oxyethylene/oxypropylene) polyamine products are prepared using an initiator, which may contain oxyethylene groups. In a series of alkoxylation reaction steps the initiator is reacted with predetermined weight percentages of ethylene oxide and propylene oxide, said process comprising the steps of: a. Charging a predetermined percentage of initiator to an alkoxylation reaction zone, b. Alkoxylating said initiator therein with predetermined percentages of ethylene oxide and propylene oxide to provide an intermediate polyol, c. Propoxylating said intermediate polyol with a predetermined percentage of propylene oxide to provide a normally liquid, water-soluble precursor polyol, and d. Catalytically reductively aminating said precursor polyol in the presence of a reductive amination catalyst in a reaction zone under reductive amination conditions in the presence of ammonia and hydrogen to provide said water-soluble poly(oxyethylene/oxypropylene) polyamine product. |
