The Influence of a Novel Decolorization Method on the Decolorization Effect of Alkyl Glycosides
After the synthesis of alkyl glycosides by one-step method,a powerful self-priming multi-phase flow pump is adopted during bleaching to change the bleaching system from conventional stirring system to circulation system,the phenomenon in the bleaching process using the new method and the common method is analyzed and the detection data of bleaching products is compared.The influence of temperature,pH and pump parameters on the product are also investi-gated,and the optimal bleaching and decolorization conditions has been obtained:the decolorization temperature is con-trolled at 70-80 ℃,the pH is controlled at around 12,and the pump flow rate is controlled at 40 m3/h.Under the above conditions,the obtained products have light color and good quality.
