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.

摘要： Implementations described herein relate to an etheramine mixture containing a cyclobutane based amine and its method of production by alkoxylating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the ehteramine mixture. The etheramine mixture may be used in a variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea materials.
