| Abstract: | Dialdehyde starch is a important chemical material for it has low toxicity,high chemical reactivity and extensive applications in all sorts of industry, but in China research and production of dialdehyde starch are belong to developing step.This paper uses corn starch as material and sodium periodate as oxidant, and adopts orthogonal method to study optimal experiment conditions of preparing dialdehyde starch, which is that reaction temperature 35℃, reaction time 3.5 hours, reaction concentration of sodium periodate 0.5mol/L, pH4 and ratio of sodium periodate to starch 1.1:1. |
