An etheramine mixture comprising one or more polyether diamines, methods for its production, and its use as a curing agent for epoxy resins. The etheramine mixture may also be used in the preparation of polyamides and polyurea compounds.

Etheramine mixture containing polyether diamines and method of making and using the same

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.

Etheramines prepared from a mixture of two or more multifunctional alcohol initiators, and their use as curatives or intermediates for polymer synthesis

Etheramines and their use as curatives or intermediates for polymer synthesis

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.

Etheramines with enhanced thermal stability and their use as curatives or intermediates for polymer synthesis

The present invention relates to an etheramine mixture containing a monoether diamine 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 etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea.

Etheramines and their use as intermediates for polymer synthesis

The present invention relates to an etheramine mixture containing a monoether diamine and its method of production by alkyloxating an initiator with an alkylene oxide to produce a precursor polyol and reductively aminating the precursor polyol to form the etheramine mixture. The etheramine mixture may be used in variety of applications including as a curing agent for an epoxy resin or as a reactant in the production of polyurea materials.

Etheramines containing flexible and rigid segments and their use as intermediates for polymer synthesis

In another exemplary embodiment, an amine functional curing agent has an Amine Hydrogen Functionality (AHF) of at least 7 and an Amine-Hydrogen Equivalent Weight (AHEW) of at least about 50.

High functionality amine compounds and uses therefor

Provided herein are polyamine precursors useful in the manufacture of epoxy resins. Use of a polyamine precursor according to the invention provides an epoxy resin formulation having an increased working time over prior art amines used for curing epoxies. Increased working times translate to the ability to manufacture composites which could not be made using conventional epoxy curing agents, such as composite blades for wind-driven turbines. Such polyamines are also useful in polyurea formulations for lengthening reaction time, thus allowing more flow of applied polyurea coatings prior to gellation.

Polyether polyamine agents and mixtures thereof

Provided herein are catalysts useful in reductive amination, which include nickel, copper, zirconium and/or chromium, oxygen, and tin. The presence of the tin increases the selectivity of the catalyst in reductive aminations over the catalysts of the prior art.

Advances in amination catalysis

Polyether polyamine agents and mixtures therefor

A process for producing cyclohexane by benzene hydrogenation using a hydrogen source that contains impurities, such as carbon monoxide and/or light hydrocarbons, wherein a supported catalyst reduces benzene to cyclohexane and carbon monoxide to methane and water. Alkenes, such as ethylene, are also reduced to their alkane counterparts. Under the disclosed operating conditions, the process proceeds without deactivation of the catalyst, and without the formation of a significant amount of cracking products, such as methylcyclopentane.

Manufacture of cyclohexane from benzene and a hydrogen source containing impurities

This invention concerns a fuel additive comprising an etheramine alkoxylate, and fuel compositions and additive concentrates made therefrom. The etheramine alkoxylate may be of formula: ##STR1## where R.sup.1 is a straight or branched alkyl, or alkylaryl; R.sup.2 is independently in each occurrence hydrogen or alkyl from 1 to 6 carbons; R.sup.3 is independently in each occurrence hydrogen or alkyl of from 1 to 6 carbons; m averages from about 2 to about 20; and x and y each independently average from about 0 to 2, where x+y averages from about 1 to about 4.

Fuel compositions containing etheramine alkoxylates

Etheramine alkoxylates are described which have the formula: ##STR1## where R.sup.1 is a straight or branched alkyl, aryl or alkylaryl group of 6 to 22 carbon atoms; R.sup.3 are independently hydrogen or C.sub.1 to C.sub.3 alkyl; m averages from about 1 to about 20; and x and y each independently average from about 0 to 30, where x+y averages from about 2 to about 60. These etheramine alkoxylates have surfactant properties. Further, they may be quaternized to make other compounds which will have useful surfactant properties.
