Liquefied wood as a partial substitute of melamine-urea-formaldehyde and urea-formaldehyde resins [PDF]
Maderas. Ciencia y Tecnología, 2015 Maritime pine (Pinus pinaster) sawdust was used to produce liquefied wood by the polyhydric method with acid catalysis. The process was optimized to produce the highest amount of liquefied wood. Wood liquefied at 160ºC for 90 min was used in the adhesion tests.

Resolving a Nearly Two-Centuries-Old Mystery: On the Structural Chemistry and Physicochemical Properties of Compounds Associated With the Term Ammelide. [PDF]
ChemistryThe crystal structure of ammelide, also known as melanuric acid, was solved almost 200 years after its discovery by Liebig. Moreover, three modifications of its 1:1 adduct with ammeline were structurally elucidated, consisting of layers with a honeycomb motif analogous to melamine cyanurate.
