Study on the Effect of Distillation Residue in Corn Polyols Industry on Thermoplastic Starch

Abstract:

This study used distillation residue obtained from bio-refinery process of corn starch and glycerol as a plasticizer to prepare thermoplastic starch (TPS). Various weight ratios of distillation residue and glycerol was investigated, HPLC method was used to analysis the components of the distillation residue. The composition and structure of TPS were evaluated by FTIR, XRD and TGA. The results indicated that with the addition of mixed plasticizers, the structure of TPS was changed obviously from a crystal state to an amorphous one with an increasing thermal stability of TPS. The better TPS structure can be obtained when the weight ratio of distillation and glycerol is 3:7.
