Methyl ester sulphonates (MES) have been considered as an alternative green surfactant for the detergent market. Investigation on the purification of methyl ester sulphonates (MES) with various carbon chains of C12, C14, C16 and C16–18 derived from palm methyl ester is of great interest. These MES powders have been repeatedly crystallized with ethanol and the purity of MES has increased to a maximum of 99% active content and 96% crystallinity index without changing the structure. These crystallized MES with high active content have 1.0% to 2.3% moisture content and retained its di-salt content in the range of 5%. The crystallized MES C16 and C16–18 attained excellent flow characteristics. Morphology, structural and its crystallinity analyses showed that the crystals MES had good solubility properties, stable crystal structure (β polymorphic) and triclinic lateral structure when it is in high active content. The brittleness of MES crystals increased from a β’ to a β subcell. Crystal with high brittleness has the potential to ease production of powder, which leads to a reduction in the cost of production and improves efficiency.

Kinetics Of

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.
