5-Methylfurfural CAS 620-02-0

Record 1.
In a 25ml quartz cellular lining with a magnetic stirrer, add 0.1804 g fructose, 30mg tungsten carbide (WC), 0.4 ml mass fraction of 55-58% hydroiodic acid, 1.6 ml distilled water, 5ml toluene, recognized mass n-decane, and then placed the quartz lining with the medicine in the high-pressure response kettle open, shut the kettle, change the air in the reaction pot with high-purity hydrogen, and after that remain to load it with hydrogen to make the interior pressure 300 psi, and also check that there is no leakage. After gassing, position the reaction pot in an oil bath at 130 ° C for 60 minutes. After enough cooling, wear down the gas as well as open up the pot. Take the upper toluene phase and weaken it for gas chromatography evaluation. The test results show the molar yield of 5-Methylfurfural. 61%.

Report 2.
Add 100 mg starch, 2 mmol salt iodide, 2 ml water, 0.18 mmol HCl (37 wt%), and also 3 ml n-octane to a 50 mL high-temperature as well as high-pressure response pot, secure the reaction kettle, load it with hydrogen (100 psi), mix as well as swiftly warmth to 180 ° C, keep for 1h. Trendy the reaction pot to area temperature level in an ice-water bath, accumulate the natural stage and discover it. The yield of 2-methylfuran is 4.2%, the return of furfural is 1.6%, and also the return of 5-Methylfurfural is 10.1%. The total return is The price is 15.9%.
