WebMethyl acetate is a volatile colorless liquid, somewhat soluble in water (25%) and miscible with other organic solvents such as alcohols and ethers. Methyl acetate has a melting point of −98 °C. Its boiling point of 56.9 °C is very close to that of acetone (56.05 °C), making the separation of a mixture of the two compounds via fractional distillation complicated. assi pulkkinen assip pukWebWater spray may reduce vapor, but may not prevent ignition in closed spaces.
