Chemical Properties Colorless liquid, volatile, aromatic. Solubility in water 30.4g/100ml (20ºC). Miscible with ethanol, soluble in ether, methanol. Uses It is used as raw material of acetate fiber and DMF, solvent of pesticide carbendazim insecticide, curing agent in phenolic resin, fumigant of fruit and tobacco, and raw material of organic synthesis. It can produce formic acid, formamide, dimethylformamide, ethylene glycol, trichloromethyl chloroformate, glyoxate, acetic anhydride, acetic acid, etc. It is also used in the production of pesticides, military gases and solvents. Methyl formate is also used as a solvent for cellulose nitrate and cellulose acetate, as an intermediate in pharmaceutical manufacturing, and as a fumigation fungicide. Uses as a solvent for chromatographic analysis of standard substances and acetate fiber, also used for organic synthesis as a raw material for acetate fiber and DMF, a solvent for pesticide carbendazim insecticide, a curing agent in phenolic resin Chemicalbook, used as a fumigation agent for fruits and all kinds of tobacco purposes Gas chromatography standard substances, solvents, organic synthesis, fungicides, insecticides, Smoking agent. Production method 1. Direct esterification method obtained by esterifying formic acid with methanol. Mix anhydrous calcium chloride and formic acid and stir to cool. Slowly add the methanol. Reflux 2.5h, distillation to obtain the finished product. During the reaction, formic acid and methanol can also be heated to reflux without adding calcium chloride, and the distillate with a relatively dense concentration of 0.947 can be distilled to obtain methyl formate with a yield of 90%. Raw material consumption quota: formic acid 845kg/t, methanol 600kg/t. 2. Carbon dioxide method in boron trifluoride methanol solution, using iridium complex as catalyst, through carbon dioxide and hydrogen, reaction at 100ºC, 5.88MPa to produce methyl formate. 3. Methanol carbonylation method. 4. Methanol dehydrogenation method. 5. Methanol oxidative dehydrogenation method. 6. One step synthesis of synthetic gas.
