Flash point is the lowest temperature at which a liquid can form an ignitable mixture in air near the surface of the liquid. The lower the flash point, the easier it is to ignite the material. The lower the flash point, the easier it is to ignite the material.
MeTHF is safer due to its lower volatility and higher flash point. MeTHF has a higher boiling point, resulting in less solvent lost to the atmosphere. MeTHF is inversely soluble in water. MeTHF is easier to recycle and dry. MeTHF is more stable in both acidic and basic conditions. MeTHF degrades about 6x slower under typical process conditions.
Sep 28, 2000· In the presence of a catalyst the resultant chemical reactions include multiple hydrogenations and two dehydration steps to produce MTHF. On a weight basis, the yield is 63 pounds of MTHF for every 100 pounds of levulinic acid (Alternate Fuels Data Center, 2000; Hoffman, 1998; OTI, 2000; Science Daily, 1998).

Flash Points of Common Flammable Substances. Important: The flash point is NOT the temperature at which the vapour will spontaneously ignite. The vapour must be exposed to a heat source at or above its Auto-ignition Temperature which is the minimum temperature required to ignite a gas or vapour in air without a spark or flame being present.
Flash point, the lowest temperature at which a liquid (usually a petroleum product) will form a vapour in the air near its surface that will "flash," or briefly ignite, on exposure to an open flame. The flash point is a general indication of the flammability or combustibility of a liquid.
