    摘要: 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 using 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.

    摘要: This invention concerns a composition useful as a paint remover, comprising: alkylene carbonate such as propylene carbonate or ethylene carbonate, hydrogen peroxide, and water, and optionally an alcohol such as benzyl alcohol. In another broad respect, this invention concerns a process for removing paint, comprising: applying a composition containing alkylene carbonate, hydrogen peroxide, and water to a painted surface for a time and under conditions effective to cause blistering or bubbling of the paint. In another broad respect, this invention is a composition useful as a paint remover, comprising: dialkyl carbonate, hydrogen peroxide, and water, optionally containing an alcohol, optionally containing a glycol ether. In another broad respect, this invention is a process for removing paint, comprising: applying a composition containing dialkyl carbonate, hydrogen peroxide, and water to a painted surface for a time and under conditions effective to cause blistering or bubbling of the paint.
