Abstract: 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.

Abstract: Process for preparing a polyol comprising particulate material in dispersed form by reacting an MDI-based polyisocyanate and a polyol having an equivalent weight of up to 400 in a relative amount such that the number of NCO-groups is 70-100% of the number of OH-groups in said polyol having an equivalent weight of up to 400, the reaction being carried out in a polyol having an equivalent weight of 500 or more. The polyols are claimed as well.

Abstract: Embodiments of the present invention disclose a process for the co-production of bis(para-aminocyclohexyl) methane (PACM). Also disclosed are articles of manufacture made using PACM produced by methods of this invention. The methods of the present invention generally include a first mixture having methylene di-aniline (MDA) and a second aromatic amine. The first mixture has less than 15% polymeric MDA by weight and the second aromatic amine is present in an amount to render the first mixture a liquid. The first mixture is hydrogenated to produce a product mixture comprising PACM and at least one second non-aromatic amine.

Abstract: Provided herein are compositions of matter which contain an agriculturally-active material in combination with an agricultural adjuvant and at least one alkylene carbonate. The presence of an alkylene carbonate in such formulations increases the efficacy of herbicides and pesticides used in controlling unwanted foliage and insects in commercial agriculture.

Abstract: Method of preparing diaminodiphenylmethane and higher homologues thereof from aniline and formaldehyde in the presence of heterogeneous solid acid catalysts selected from (a) delaminated zeolites and/or (b) metal silicate catalysts having an ordered mesoporous pore structure and/or (c) delaminated phyllosilicates.

Abstract: A chemical softening composition includes a amide-substituted quaternary imidazolinium salt, a nonionic surfactant, and a polyhydroxy compound for use in treating cellulosic materials including papers, textiles and fabrics.

Abstract: 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.

Abstract: The present invention concerns a process for providing tertiary amine products which are color-stable, and have a greatly reduced tendency to take on color during their storage. According to the invention, an ethyleneamine derivative is added to the distillation pot prior to or during the distillation of the tertiary amine product. Preferably, the ethyleneamine derivative has a higher boiling point than the desired tertiary amine product so as to preclude the ethyleneamine from distilling over with the tertiary amine.
