WebThe amount of water released per citric acid molecule, on average, can be calculated from this data. The higher this number is, the higher the degree of cross-linking, because a molecule reacting with a Kaumera chain releases 1 water molecule, whereas a citric acid molecule reacting with another releases only 0.5 water molecules per CA molecule. WebThe presence of citric acid while cross-linking with silane increased the viscosity (SM – 05), as the citric acid helped to open starch molecules and to form ester linkages at temperatures well above 95 to 97 °C (Yu et al. 2005).
