粗孔微球硅胶为乳白色颗粒，主要成分为二氧化硅，不溶于水和无机酸。其内部结构为孔容0.80-1.30ml/g，孔径80-120Å，比表面积300-550㎡/g。

The coarse pore microsphere silica gel is a milky white particle, the main component is SiO2·nH2O, insoluble in water and inorganic acid, soluble in hydrofluoric acid and concentrated caustic soda solution. The pore volume is 0.80-1.30ml/g, pore size 80-120Å, specific surface area 300-550㎡/g.

本品主要用于苯酐、苯胺、顺丁烯二酸酐、三聚腈氨、丙烯腈等重要石油化工产品的催化剂及催化剂载体，也广泛用于精制石油产品、对某些有机气体及液体组分的选择性吸附分离。还可作为脱除水中多价有害元素的离子交换剂以及用于材料、器械等物品的干燥储存和高纯气体的除水精制。    

The product is mainly used as catalyst and catalyst carrier for important petrochemical products such as phthalic anhydride, aniline, maleic anhydride, cyanamide, acrylonitrile, etc. It is also widely used for refining petroleum products, selective adsorption and separation of some organic gases and liquid components. It can also be used as an ion exchanger to remove polyvalent harmful elements from water, as well as for dry storage of materials, instruments and other items and dewatering purification of high purity gas.
