This work reports that cellulose laurate could be directly produced by mechanical activation-strengthened solid phase synthesis (MASPS) in a customized stirring mill with using bagasse pulp and lauric acid as materials in an environmentally friendly way. Cellulose laurates with different degree of substitution were obtained under different synthesis conditions without the use of organic co-reagents and solvents. The characterization results showed that cellulose laurates had great changes in surface morphologies and crystal structures compared with bagasse pulp because of the intense milling and introduction of laurate groups, but still retained the cellulose I crystalline form of the native cellulose. MASPS could be considered as a simple, efficient and green method for the production of long chain cellulose esters.
本工作报道了一种在定制搅拌磨机中通过机械活化强化固相合成（MASPS），以蔗渣浆和月桂酸为原料，直接绿色合成月桂酸纤维素酯的方法。在不同的合成条件下，无需使用有机溶剂和共试剂，得到了不同取代度的纤维素月桂酸酯。表征结果表明，由于强烈的研磨和月桂酸基团的引入，与蔗渣浆相比，纤维素月桂酸酯的表面形貌和晶体结构发生了很大的变化，但仍保留了天然纤维素的纤维素 I 晶型。MASPS 可以被认为是一种简单、高效、绿色的长链纤维素酯生产方法。
