Synthesis and Kinetics of a Green Surfactant Alkyl Glucamines

Abstract

Using glucose and N-butylamines as the main feedstocks in the normol pressure, a novel green surfactant alkyl glucamines was synthesized through hydroammonolysis reaction in the presence of recombination macromolecule organic acid as catalyst. The synthesis technical of alkyl glucamines was studied systematically. The results showed that the conversion was more than 65% when the quantity ratio of glucose to amine was 1︰4, pH was 8.5 around, reaction temperature was 50°C for 60h about. The reaction mechamnism and kinetics of glucose hydroammonolysis was discussed simultaneously. The kinetic model on the synthesis of alkyl glucamines was built： ＝ －0.0117 t －1.3502. The correlation coefficients of the model were gained precisely, and the model was credible by the statistical test and experiment.
