    Research on the Preparation and Performance of Binary Modified Maltodextrin Water-Reducing Agent by Jingzhi Wu, Min Qiao, Zhifeng Lyu, Qianping Ran

    Published 2016-01-01
    “…The results show that the optimal conditions of sulfonation were the MD of DE 15, m (sulfonated agent)/m (MD) of 1.4, the catalyst amount of 1% by mass MD, and the reaction time of 12 h; the optimal conditions of esterification were m (esterified agent)/m (SMD) of 0.6, the reaction temperature of 90°C, and the reaction time of 4 h. The optimal dosages of sulfonated maltodextrin (SMD) and BMMD were 0.475% and 0.45%, respectively. …”
