  • Patent number: 8414797
    Abstract: 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 120° F. 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.

  • Patent number: 8354042
    Abstract: A method of raising the flash point of a green solvent includes adding from about 0.05 to 5.0 wt. % of at least one terpene alcohol, based on the weight of the at least one terpene alcohol and the green solvent. Green solvents are derived from organic matter, such as plants. They are not the product of petroleum feed stocks. Preferably, two terpene alcohols are added to the green solvent. Further, the addition of at least one terpene alcohol improves both the freeze resistance and the shelf life of the final green solvent solution.
