树脂材料在烷基多苷脱色技术中的应用

Resin material application in the alkyl poly-glycosides decolorization technology

摘要:

采用弱碱阴离子交换树脂，研究淀粉糖苷表面活性剂的动态吸附脱色，脱色后产品不产生pH值漂移、稳定性好、透明度高、澄清无絮状沉淀、不产生不愉快气味、无机盐含量低、操作简单、脱色时间短、易再生。470nm波长下吸光度为0.058，强化实验72h吸光度为0.051。红外和气相色谱分析证明脱色前后淀粉糖苷结构无变化。

Abstract:

The dynamic adsorption decolorization technology of alkyl poly- glycosides surfactant with weak basic anion-exchange resins was studied. The decolorization products of PH is no evident change, it also has good stability, high transparency and clarification, no flocculent deposition; no bad smell; inorganic salt is low quantity percent, operation method is brief and rapid, which macro-porous weakly basic anion exchange resins is easy regeneration. Absorbance is 0.058 at 470nm wavelength. At Strengthening Experimental, the absorbance is 0.051 within 72h.Through measurement technique of IR and gas chromatography proved that the structure of alkyl poly-glycosides surfactant remain unchanged.
