The present invention relates to a method to decrease the flammability of normally flammable alcohols and solvents.

With certain percentage mixes of alpha terpineol the flash point is raised and the physical characteristics of the solvent are not harmed. When tested it exhibited a flash point of −4.2 C using Pensky-Martens Closed Cup Flash Point Tester. The melting point ranges from −47.87 °C (−54.17 °F) (m-xylene) to 13.26 °C (55.87 °F) (p-xylene)—as usual, the para isomer's melting point is much higher because it packs more readily in the crystal structure. endobj 147 °C. In August, the spread between MX and downstream PX strengthened, thus encouraging more PX producers to buy MX and increase operating rates. Xylenes are released into the atmosphere as fugitive emissions from industrial sources, from auto exhaust, and through volatilization from their use as solvents.
According to the Condensed Chemical Dictionary 1956 edition, Reinhold Publishing Company, n-methyl pyrrolidone has a flash point of 204 F and dibasic ester has a flash point of 212 F. Those skilled in the art will recognize that the alpha terpineol/solvent blend may themselves be used to remove grease and other contaminants from various materials, such as steel, aluminum, and other substrates.
