Scientists have discovered a new method of synthesis of Furans-2,5-dicaroxic acid (FDCA), which generates undesirable vegetable cellulose glucose that stimulates the use of plastic bottles with alternating sodium acids substitutes.


The chemical industry puts pressure on energy efficient chemical procedures that do not produce products and renewable resources where possible. Scientists believe that if unwanted plant resources can be used for the environmental burden, it will support existing social systems.

It is known that various useful polymers can be synthesized from 5 (hydroxymeal) purple (HMF), biomass used in this study. FDCA's high yield can be obtained when the HMF is a rinse solution solution with a 2% weight weight (wt percent) with different metal catalysts. However, the major obstacle to the industrial application is to use a concentrated solution of 10-20 wt percent, which is essential for the FDCA's efficient and massive industry in the field of chemical industry. When HMF only oxidized concentrated solution (10 wt percent), the FDCA yield was only 30 percent, and a large amount of solid product was formed simultaneously. This is due to complex side effects caused by HMF.

Published research Army Chemie International Edition, Associate Professor Kyotaka Nakaj at the University of Hawaii Research, Professor Emilie Jim Hennen, Eindhoven University of Technology, successfully undergone adverse reactions and formation of FDCA high concentrated HMF solutions (10 ~ 20 wt percent). In particular, they are the first to break the 1,3-propane polygon, which are used in the form of groups of products and then the hydroelectric functional AEP catalyst Au catalyst.

1.3-Propandidolis 80 percent, which is used to protect form groups, can be used for further reactions. In addition, the sharp improvement of the substrate concentration reduces the number of solvents used in the production process. Kyotaaka Nakaiji says: "It is important that our method is to reduce overall energy consumption, which is necessary for a complex work process to isolate the reaction product."

"These results constitute an important advancement of the current state of the art that overcomes the limitation of HMF delay in producing biopolymers on an important monomer." Shaped group "reactivity control can open the pitcher for the chemical chemicals to produce biomass", says Kyotaka Nakimama. This research was conducted jointly by Mitsubishi Chemical Corporation.
