Kieselgel-Pulver has good thermal stability and chemical stability. It can selectively adsorb and purify isomer components from multi-component solutions. In the process of preparing Kieselgel-Pulver, a series of products with an average pore diameter of 20A°-20000A° can be produced by controlling different process conditions to adapt to the separation and purification of substances with different properties, molecular weights and molecular structures. The purity of Kieselgel-Pulver is as high as 99%. Compared with organic column packing, silica gel is a solid colloid with SiO2 as the matrix, and has a compact structure. Even if it is directly discarded, organic matter will be lost and the target product will be contaminated.
