Synthesis and Characterization of Chitosan Based Ultraviolet Absorber with Groups of Benzophenone

Abstract:

2-hydroxy-4-glycidyl ether benzophenone(HGEBP) is synthesized with 2,4-dihydoxy- benzophenone(UV-0) and epichlorohydrin(ECH) as starting material, then a series of chitosan (CS) based novel ultraviolet absorbers (CS-g-UV-0) are synthesized by the reaction of chitosan with HGEBP in isopropylcarbinol in the presence of sodium hydroxide. The products(CS-g-UV-0) are characterized by means of Fourier transform infrared spectra (FT-IR), X-ray diffraction (XRD), and UV spectrophotometer. The results of UV absorption show that anyone of the grafted products has a strong ultraviolet absorption area ranging from 280nm to 350nm and the maximum absorption peak presents at 291 nm. It is found that the grafted products could improve the moisture-absorption and moisture-retention property with the increase of G% values.
