Solvent systems and methods of producing high flash point solvent systems including terpenes

Patent No. 8,414,797

Issued: April 9, 2013
Filed: January 6, 2012

Inventors: Howard; Harry W. (Little Egg Harbor, NJ), Rexer, Jr.; William F. (Binghamton, NY) 
Assignee: Greensolve, LLC (Binghamton, NY)


Compositions and solvent mixtures include at least one organic solvent and at least one terpene. In some embodiments, the terpene is a monoterpene. In some embodiments, the terpene is pure gum turpentine, oil of turpentine, a component of turpentine, or a combination of these. In some embodiments, the organic solvent is acetone or a green solvent. Addition of a minimal amount of terpene to the organic solvent or organic solution raises the flash point of the mixture, preferably to a predetermined value. The predetermined value is preferably in the range of 110 to 120F. The amount of terpene is preferably in the range about 0.05 to about 5 percent by total weight of the mixture. In some embodiments, the compositions are used as coatings, such as paints or adhesives. In some embodiments, at least one terpene is added to a lubrication formulation.
