摘　　要：试验研究了L-岩藻糖在乙腈-水混合溶剂中的溶解度及其粒度调控工艺,进行了热力学模型关联分析,并采用激光粒度仪对L-岩藻糖的粒度进行了表征。结果表明:L-岩藻糖的溶解度随着乙腈含量的增多而减小,并与温度呈正相关关系。CNIBS/R-K模型对L-岩藻糖溶解度的拟合效果要优于Apelblat修正模型和Apelblat-JouybanAcree修正模型。L-岩藻糖可以通过控制乙腈的流加速率来直接获得粒度介于68~462μm的产品。The solubility of L-fucose in acetonitrile-water solvent system and its particle size control process were studied.The thermodynamic model correlation analysis was carried out to analysis the solubility data. The particle size of L-fucose was characterized by laser particle size analyzer. The results showed that the solubility of L-fucose decreased with the increase of acetonitrile content and was positively correlated with temperature. CNIBS/R-K model was better than the modified Apelblat model and the modified Apelblat-Jouyban-Acree modified model in fitting the solubility of L-fucose. L-fucose could be directly obtained with particle size between 68 μm and 462 μm by controlling the flow rate of acetonitrile.
