| titleOfInvention | A method of hemicellulose being prepared into furfural using continuous flow micro passage reaction |
| abstract | The invention belongs to organic synthesis field, specially a kind of method that hemicellulose is prepared into furfural using continuous flow micro passage reaction.Method includes the following steps: hemicellulose aqueous solution and catalyst containing polymerization inhibitor are controlled molar ratio via metering pump；Into carrying out hybrid reaction in micro passage reaction, after hybrid reaction, continue through a series of mass transfer enhancement type microchannel modules and flow pattern microchannel module, after the completion of reaction process, product enters gas-liquid separator after the outlet of reactor outflow and carries out gas-liquid separation, furfural and vapor mixed gas be discharged into fractionating column by throttle valve by upper airway, and liquid falls into separator.It is raw material that this method, which is utilized with the hemicellulose that chemical fibre industry spent lye recycles, hemicellulose is directly translated by furfural using continuous micro passage reaction, by separation, the mode of catalyst is recycled, make yield, economic benefit, reduce pollution, improve the ecological environment etc. is improved a lot. |
