Among the solid acids, heteropoly acids (HPA) show strong and Brønsted acidity.
The experimental results demonstrate that a mixture of both solid acids provides a better combination of Brønsted and Lewis acidity for effective glucose dehydration into HMF than each individual catalyst.
A few years later the separation of liquid acids from solid acids was accomplished.
We calculate the layered solid acids' structures and bandgaps.
They are powered solid acids principally comprising zeolites, matrix, binder and sometimes additives.
XRD patterns of the solid acids under different conditions are shown in Fig. 3.
These hybrid matrixes aim further developments either to embed solid acids nanoparticles or to design strong solid acids on nanooxides, making them appropriate for proton exchange membranes.
Although solid bases were totally inactive, solid acids exhibited high activity to yield dienes.
This was attributed to differences in the degradation mechanisms of polystyrene over solid acids and bases.
This work describes the acetylation of glycerol with acetic acid catalyzed by different solid acids.
The catalytic properties of the solid acids were evaluated using esterification of methanol with acetic acid.
