Luft- und Wasserreaktionen:Highly flammable. Water soluble. Reacts slowly with water to give formic acid, a corrosive material, and methanol, a flammable liquid. Both products are dissolved in the water.
Reaktive Gruppe:Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Reaktivitätsalarme:Highly Flammable
Reaktivitäts-Profil:METHYL FORMATE reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides.
