专利号:US-11292873-B2 优先权日:2013-11-05 标 题 :Etheramines prepared from a mixture of two or more multifunctional alcohol initiators, and their use as curatives or intermediates for polymer synthesis 发明人:ZHOU HUI; LEWIS DAVID C; KLEIN HOWARD P; RENKEN TERRY L; PATTERSON LEAH 权利人:HUNTSMAN PETROCHEMICAL LLC 摘要:Implementations described herein generally relate to etheramine mixtures formed from a mixture of two or more multifunctional alcohol initiators, processes for the etheramine mixtures production, and its use as a curing agent or as a raw material in the synthesis of polymers. In one implementation, the process comprises mixing a polyol initiator having a melting point greater than a processing temperature and a polyol initiator having a melting point less than the processing temperature to form a polyol initiator mixture having a melting point less than the processing temperature, charging the polyol initiator mixture to an alkoxylation reaction zone, contacting the polyol initiator mixture with an alkylene oxide in the alkoxylation reaction zone to provide a mixture of alkoxylated precursor polyols and charging the mixture of alkoxylated precursor polyols to a reductive amination zone and reductively aminating the mixture of alkoxylated precursor polyols to form the etheramine mixture.
