Versuchsvorschrift
About 2 mols of furfural are mixed with one mol of the diurea silicate and heated to just below the boiling temperature of furfural while agitating at ambient pressure for 20 to 120 minutes, until the desired viscosity is obtained, thereby producing poly (furfural diurea silicate) resinous product.
Aufarbeitung
- customuntil the desired viscosity is obtained
