Study on Modified Starch by Glutaraldehyde and its Properties and Application

Abstract:

The modified starch was prepared by degradation starch with glutaraldehyde. The process conditions of degradation and modification starch were investigation. The result shows that the degradation starch was obtained through 22.5 g cornstarch and 1g ammonium persulfate (APS) in 127.5 g water at 95°C for 1h, and the modified starch was obtained by aldolization reaction of degradation starch and 4 mol/AGU glutaraldehyde at 85°C for 5h. The modified starch can be used as leather tannage. The shrink temperature (T_s) of tanned leather can be increase from 41.6 °C to 85.2°C. It may replace chrome tannage and decrease the pollution produced in chrome tanning processing. Meanwhile, the chemistry structure of modified starch was characterized by FTIR, ¹H-NMR, ¹³C-NMR
