  • Patent number: 6586380
    Abstract: 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.

  • Patent number: 5912382
    Abstract: High purity hydroxyalkyl carbamates having alkyl groups with two, or three or more carbon atoms may be produced from anhydrous ammonia and alkylene carbonates at relatively low pressures, such as in a low pressure conventional kettle process. In this method, a reactor vessel is typically evacuated prior to reaction and anhydrous ammonia and alkylene carbonates are typically reacted in the presence of an initiator. Using this method, hydroxypropyl carbamate products having a purity greater than about 97%, and hydroxybutyl carbamate products having a purity greater than about 95% may be produced. Hydroxybutyl carbamate compositions comprising mixtures of 2-hydroxylbutyl carbamate and 1-hydroxymethyl propyl carbamate may also be produced.
