Process for the production of superfluid microcrystalline cellulose

By combining inorganic-organic hybrid metal oxide framework materials with microcrystalline cellulose, a hollow mesoporous structure and strong interfacial bonding are formed, which solves the problems of poor flowability of microcrystalline cellulose and easy separation and failure of inorganic flow aids, and realizes the production of microcrystalline cellulose with high flowability and good compressibility.

Abstract

本发明公开了微晶纤维素技术领域的一种超级流动性微晶纤维素生产工艺;包括将木浆分散于去离子水中,加入盐酸加热水解,骤冷终止反应,经压滤、水洗、稀氨水中和后再水洗得到湿滤饼;将湿滤饼与无机‑有机杂化金属氧化物骨架材料及十二烷基硫酸钠混合研磨,水洗脱除表面活性剂后进行干燥,再经混合与振动筛分即得流动性优异的微晶纤维素成品。所得产品颗粒分散均匀,可满足高速压片对流动性的要求。
