Introduction | methyl 2-furoate is one of the most important fine chemicals derived from biomass, in the field of biomass conversion caused widespread concern. The chemical name of methyl 2-furoate methyl ester is methyl 2-furan formate, also known as methyl carbamate. Methyl 2-furoate is one of the important derivatives of furan ring compounds. The active center of methyl 2-furoate is carbonyl, and the carbonyl has high reactivity and large polarity, because of the furan ring and aldehyde group in the molecule, it is easy to occur furfural hydrogenation, oxidation, reductive amination, decarbonylation and other reactions. |
Application | methyl 2-furoate is an extremely important new synthetic flavor, widely used in food flavor, tobacco flavor, cosmetics and other industries. At the same time, it is an important chemical raw materials and intermediates, can be used as gasoline antiknock agent to improve the quality of gasoline, but also has anti-tumor activity. |
preparation | methyl 2-furoate was prepared with furfural as substrate and supported nano-gold as catalyst: 0.05g of furfural was dissolved in 15ml of methanol, 0.05g of supported nano-gold, G of auxiliary agent potassium carbonate, and the oxygen atmosphere was 0.3MP, at a temperature of 140 deg C, stirring speed 120 r/min conditions, the reaction for 4 hours, by supported Nano Gold selective catalytic oxidation of furfural, methyl furoate. The results of the reaction were analyzed by GC-MS and GC. The conversion of furfural was 92.98% and the selectivity of methyl 2-furoate was 98.72%. |
toxicity | GRAS(FEMA). |
usage limit | FEMA(mg/kg): Beverage 0.61; Cold beverage 0.06~1.3; Candy 0.66; baked products 1.0~1.3; Condiment 0.02. |
Use | for organic synthesis, also used as solvent |
production method | is obtained by esterification of furoic acid with methanol. Furoic acid was dissolved in methanol, concentrated sulfuric acid was added, and then heated and boiled for 4H. The product was obtained by cooling, washing, neutralization and distillation. |
