This application relates, in part, to novel salts represented by the following structure of Formula (1): wherein Ris selected from the group consisting of hydrogen and optionally substituted alkyl (e.g., unsubstituted Calkyl, e.g., —CH); Ris optionally substituted alkyl (e.g., unsubstituted Calkyl, e.g., —CH); each occurrence of Rand Ris independently selected from the group consisting of hydrogen, optionally substituted alkyl, optionally substituted cycloalkyl, and optionally substituted aryl; Rand Rcan combine with each other to form optionally substituted cycloalkyl; each m and n is independently an integer ranging from 1 to 20 (e.g., m and n is independently an integer ranging from 1 to 5); and each of Qand Qis independently a counterion (e.g., each of Qand Qis independently a counterion selected from the group consisting of chloride, bromide, fluoride, iodide, acetate, carboxylate, hydrogen sulfate, nitrate, and phenolate, and sulfonate, e.g., chloride), and methods of making the same.

Salts of diaminoacetals and diaminoketals and their synthesis, and their transformations to diaminoacetals and diaminoketals

Provided herein are silicon-containing recyclable polyamino compounds; epoxy resin compositions containing these silicon-containing reworkable or recyclable polyamino compounds; and methods of their use.

Silicon-containing compositions and their methods of use

The present invention relates to the reduction of polycyano compounds to produce polyamines, in particular diaminoacetal and diaminoketal compounds, and their use as curing agents in epoxy resin compositions. The reduction with molecular hydrogen can be carried out using a metal catalyst selected from GROUP VIII and a catalytic promoter. The reduction can include anhydrous or aqueous ammonia. The reaction can be carried out in continuous and batch modes with catalyst and solvent recycling. The epoxy resin composition consisting of an epoxy resin and a polyamine curing agent that can be used in fiber-reinforced composite materials, coating materials, and the like.
