| Ascorbic acid is needed for a variety of biosynthetic pathways, by accelerating hydroxylation and amidation reactions. |
|
| In the heterogeneous PET-DA dispersions, the amidation proceeds on the surface of the solid granules and in the liquid DA phase. |
|
| These observations proved the occurrence of the amidation reaction between poly and the amino group of POSS molecules. |
|
| Other Stepan core competencies are emulsification, amidation, quaternization, alkoxylation and peroxidation. |
|
| The direct amidation PAA was prepared according to the procedure described by Echigo et al. |
