DEPOLYMERISATION OF POLYSACCHARIDES AND RELATED PRODUCTS |
摘要 |
Procedure for depolymerising polysaccharides using UV-vis light irradiation catalyzed by a radical photoinitiator. The polysaccharides obtained with the procedure of the invention have a average number molecular weight comprised between 5,000 and 500,000 and when dissolved in water give solutions with high concentrations and low viscosity. |

1. A process for depolymerizing a polysaccharide comprising:
contacting the polysaccharide with from about 0.01 to about 10% by weight of a radical photoinitiator; homogenizing the polysaccharide and radical photoinitiator to form a homogenized mixture of the polysaccharide and the radical photoinitiator; and irradiating the homogenized mixture of the polysaccharide and the radical photoinitiator with UV-Vis rays to produce a depolymerized polysaccharide. |
