Abstract:

This invention relates to the destruction of microform materials, especially those of a confidential or classified nature. More particularly, this invention concerns itself with a chemical mixture or destruction solution for effecting the rapid destruction of microform materials. In accordance with the present invention, it has been found that a chemical mixture composed of 4-butyrolactone, methyl Cellosolve acetate and aqueous sodium hypochlorite having an optimum formulation of about 25 volume percent methyl Cellosolve acetate about 37 volume percent Am-chlor and 13 volume percent water provides an optimum destruct solution. Am-chlor is a tradename of a 12.5 sodium hypochlorite solution distributed by Amchlor Corporation Pool Chemical Division of Amato Solvents, Inc. Silver Spring, Md. The chemical destruct mixture can be incorporated in any type of destruction box, safe or other container or any type of destruction box, safe or other container or system used to destroy classified or sensitive documents. The safe can be used for both storage and destruction of classified film. Keywords Patents. aw
