| titleOfInvention | Degradation of chitosan/chitin with sulfonated carbon solid acid into high value 5-hydroxymethyl furfural |
| abstract | The invention discloses a method for preparation of 5-hydroxymethyl furfural from chitin/chitosan. The method is achieved by: taking chitin/chitosan as the raw material, adopting sulfonated carbon solid acid as the catalyst, degrading chitosan in a polytetrafluoroethylene hydrothermal reaction kettle to obtain 5-hydroxymethyl furfural, performing extraction separation, and then conducting detection with high performance liquid chromatography and carrying out quantification. The chitin/chitosan raw material involved in the invention is cheap, easily available and renewable, and also the application field of chitin/chitosan is also broadened. By adopting water and dimethyl sulfoxide as the reaction medium and catalyst, the activity of solid acid in heterogeneous reaction is enhanced. The catalyst is easy to prepare and cheap, and exists in the form of solid during reaction, and can be filtered and recovered for cyclic utilization. Also the aftertreatment is simple, and pollution to the environment is reduced. |
