标题 :Synthesis of sequestration resins for water treatment in light water reactors
发明人：YENGOYAN LEON; FRATTINI PAUL L; WELLS DANIEL MORGAN
权利人:YENGOYAN LEON; FRATTINI PAUL L; WELLS DANIEL MORGAN; ELECTRIC POWER RES INST
摘要:An organic synthesis of materials to achieve removal of low molecular weight ionic species, such as transition metal ions including cobalt, iron, nickel, and zinc, from aqueous solutions. The synthesis includes the steps of providing a cation exchange resin, functionalizing the cation exchange resin using a chloride intermediate to form a sulfonyl chloride resin, and reacting a multi-amine based ligand with the sulfonyl chloride resin to form a sequestration resin. The synthesis further includes the steps of cooling the sequestration resin, and washing and drying the sequestration resin.

标题 :Use of basic amides for increasing the porosity in paper or paper-like materials
摘要:1. Use of basic amides from amine mixtures which are obtained as tetramine bottom product in the industrial synthesis of dialkylenetriamines, in particular, dipropylenetriamine and more particularly diethylenetriamine from dihalogenoalkanes and ammonia after the triamine fraction has been distilled off or which are obtained in the industrial synthesis of diethylenetriamine and ethylenediamine from 1,2-dichloroethane and ammonia and long-chain fatty acids or fatty acid mixtures which have a melting point below 30 degrees C, for enhancing the porosity of paper or paperlike materials.

标题 :Synthesis of complex polyamines for ampholyte production

摘要:New synthesis and analysis procedures for novel crosslinked polyamines and ampholytes. Polyamines are crosslinked with tartaric acid ester, malonic acid ester, or polycarboxylic acid esters of the citric acid cycle. The resulting crosslinked polyamine may further react with other compounds such as an α,β-unsaturated or α-halo unsaturated carboxylic acids to prepare new ampholyte mixtures. The resulting novel ampholytes exhibit greater heterogeneity and complexity than presently prepared ampholytes, and can be used in analytical and preparative isoelectric focusing processes. n Novel ampholyte analysis process entails analyzing chemical compounds, usually ampholytes, used in isoelectric focusing processes. The ampholyte is isoelectrically focused on an immobilized pH gradient, and then immersed in a picric acid solution to cause precipitation and visualization of amphoteric species. The isoelectrically focused and visualized ampholyte compounds may be photographed or analyzed densitometrically to compare it with other isoelectrically focused and visualized ampholytes to determine relative heterogeneity of the ampholytes over given pH ranges.

标题:Synthesis of polyamines and mixture formed thereby, of diprimary polyalkylene polyamines with disubstituted N-adjacent terminal carbon atom(s)

摘要:A nitroamine is formed from an aliphatic amine reactant + a nitroalkane + an aldehyde with better conversion, and faster, if the aldehyde is added last, and gradually, so as not to form an alkanolamine intermediate with the aldehyde as in the prior art reactions. In particular, a diamine such as ethylene diamine (EDA) has the unique ability, even among diprimary amines, to react with nitroalkane, to form a salt intermediate to which is added an essentially solvent-free aldehyde such as paraformaldehyde to produce a reaction product consisting essentially of a mixture of (i) a mononitrodialkylenediamine with a disubstituted N-adjacent terminal C atom and (ii) a dinitrotrialkylenediamine with each N-adjacent terminal C atom being disubstituted; and the mixture is obtained in an yield of at least 90 mol %.
