Suitable curatives for the polysulfide-epoxy reaction include liquid aliphatic amines, liquid aliphatic amine adducts, solid amine adducts, liquid cycloaliphatic amines, liquid amide-amines, liquid aromatic amines, polyamides, and tertiary amines. Primary and secondary amines are preferred for thermal stability and low-temperature performance. Not all amines are completely compatible with polysulfide resins. The incompatible amines may require a three-part adhesive system. The liquid polysulfides are generally added to the liquid epoxy resin component because of possible compatibility problems. Optimum elevated-temperature performance is obtained with either an elevated-temperature cure or a postcure. 

Ring transformation of 2-amino-3-phenacyl-l,3,4-oxadiazolium halides with amines, liquid ammonia, or heterocyclic bases yields 2-amino-l-acylamino-4-arylimidazoles.145... 

As an indication of the benefits to surface cure by adding amine modified synergists, the figure below compares the reactivity of a standard formulation. The comparison shows the difference between no amine, liquid amine (n-methyldiethanolamine) and two types of synergist ("Syn" 1 and 2) which have amine values of 150 and 200mgKOH/g. 

Ring transformation of 2-amino-3-phenacyl-l,3,4-oxadiazolium halides with amines, liquid ammonia or heterocyclic bases gives l-acylamino-2-amino-4-arylimidazoles [57], When treated with an a-halogenoketone in ethanol 2,5-diamino-1,3,4-thiadiazolcs form salts, which react with hydrazine hydrate to give l-aminoimidazolin-2-thiones [58],...

Very recently, Tian and coworkers studied the structure-directing role of amines in the ionothermal synthesis of AFI-type molecular sieves in 1-butyl-3-methylimidazolium bormide ([bmimJBr) ionic liquid.[114] Their results indicated that the original crystallization process can be altered by the addition of amine. The 1H NMR spectra of [bmimJBr and amine liquid mixtures revealed that the presence of amine caused a downfield shift of the signal corresponding to the proton of the imidazolium ring, which was considered to be strong evidence for the formation of hydrogen bonds between the ionic liquid and the added amine.

Starting from n-butyl (n-butyl a-o-mannopyranosiduronate) 4, uronamides 10 bearing a short butyl chain at the anomeric position and a longer alkyl (dodecyl, octadecyl, and oleyl) chain amide-linked to the sugar head were prepared following a one-step solvent-free procedure (Scheme 8). The aminolysis reaction was performed at 65°C to make the fatty amine liquid and under reduced pressure (3 mbar) to eliminate the butanol formed all through the reaction. To avoid significant...

Epoxy-amine liquid prepolymers are extensively appHed to metallic substrates and cured to obtain painted materials or adhesively bonded stractures. Overall performances of such systems depend on the interphase created between the organic layer and the substrates. When epoxy-amine Hquid mixtures are appHed to a more or hydrated metaUic oxide layer (such as Al, Ti, Sn, Zn, Fe, Cr, Cu, Ag, Ni, Mg, or E-glass), amine chemical sorption concomitant with metaUic surface dissolution appear, leading to the organometaUic complex or chelate formation [1, 2]. Furthermore, when the solubility product is exceeded, organometaUic complexes may crystaUize. These crystals induce changes of mechanical properties (effective Young s modulus, residual stresses, practical adhesion, durability, etc.). 

The recuperation of metal ions is carried out by different types of processes such as solvent extraction [47], membrane separation [48], and chemical absorption [49]. Among these processes, solvent extraction is the most widely adopted type for the removal of metals, where the extraction agent (such as di(2-ethylhexyl) phosphoric acid, trw(2-ethylhexyl)amine, liquid phosphine oxides) is dissolved in an organic solvent (kerosene, toluene, etc.) that is used as the diluents [50,51].

Amine-based solvents have been enhanced over the years [2], such that primary (Monoethanolamine (MEA) Diglycolamine (DGA)), secondary (Diethanolamine (DEA) Diisopropanolamine (DIPA)) and tertiary (Methyldiethanolamine (MDEA) Triethanolamine (TEA)) variants are available through different suppliers, many of which include special proprietary additives to improve performance and other characteristics. The choice of a particular alkanolamine is primarily dictated by the requirements of the specific application. With the exception of a few, these amines have a maximum sorption capacity of 1 mole of CO2 to two moles of amines. Liquid tertiary amines and amidines have shown a higher sorption capacity with a ratio of 1 1 molar [3], thereby reducing the volume of amine, but the reaction rate is much slower. Amine blends have been used to compensate for this difference in order to reduce regeneration and recirculation costs and increase CO2 loading capacity.
