产品说明

一般描述

选择分子筛：
1. 一个分子对另一个分子的优先吸附取决于孔径和网孔大小。
2. 硅胶吸附特定化合物的动态能力取决于内表面积；表面积越大，动态容量越大。
3. 吸附速率和分辨率主要取决于粒径和柱填料；细小的粒度能提供最佳的清晰度。
4. 液体最易从溶解度最小的溶剂中吸附；溶剂是很好的解吸剂。
5. 强极性液体易吸附。具有羟基或含氧的化合物可被强烈吸附。
6. 对于同类化合物，分子量越高，选择性越高。
7. 分子量相近的碳氢化合物，吸附能力随双键数的增加而增加。
再生或活化：
饱和分子筛可以通过再生恢复到原来的容量，其原理涉及改变吸附剂周围的条件，以对应非常低的平衡容量。一般来说，吸附和再生的平衡能力相差越大，再生越迅速且越完全。
分子筛可以通过以下四种方式之一再生：
1. 热再活化 – 二氧化硅的最高再生温度为 300℃。
2. 压力再激活
3. 在常温常压下使适当的液体通过凝胶床。
4. 使液体中的高浓度分子通过床层置换吸附剂。
分子筛是由二氧化硅和氧化铝四面体构成三维互连网络的结晶金属铝硅酸盐。通过加热从该网络中去除天然的水合水，可产生均匀的空腔，其可选择性地吸附特定大小的分子。这种与钠离子结合的 4A 形式具有 4 Å的有效开孔，因此排除了有效直径> 4Å的分子(例如：丙烷)。 8～12 目型在液相应用中常见。分子筛在极性和非极性介质中被认为是一种通用的干燥剂。

应用

分子筛，Å可用于以下过程：

• 密闭液体或气体系统中的静态脱水，如药物、电气组件和易腐化学品的包装。
• 印刷和塑料系统中的水清洗。
• 通过吸附诸如二氧化硫、二氧化碳、硫化氢、乙烯、乙烷和丙烯等气体来干燥饱和碳氢化合物流。

选择分子筛：

2.硅胶吸附特定化合物的动态能力取决于内表面积；表面积越大，动态容量越大。
3.吸附速率和分辨率锐度主要取决于粒径和柱填充物；细小颗粒可使分辨率达到最佳的锐度。
4.液体最容易从溶解性最低的溶剂中被吸附出来；好的溶剂则可成为好的解吸剂。
5.高极性液体容易被吸附。具有羟基或含氧的化合物可被强烈吸附。
6.对于类似的化合物，分子量越大，选择性越高。
7.对于分子量相近的碳氢化合物，吸附性能随双键数的增加而增加。
再生或活化：
通过再生可以使饱和分子筛恢复其最初容量，其原理是改变吸附剂周围的条件，使平衡容量变得非常低。通常，吸附和再生的平衡容量之间的差异越大，再生越快、越完全。
分子筛可以通过以下四种方式之一进行再生：
1.加热再活化 - 二氧化硅的最高再生温度为 300℃。
2.压力再活化
3.在常温常压下，使用恰当的液体通过凝胶床。
4.将高浓度分子溶于流体中，并通过过床层，从而带走吸附物。

一般描述

Choosing a Molecular Sieve:
1. The preferential adsorption of one molecule over another depends upon pore diameter and mesh size.
2. The dynamic capacity of the silica gel for adsorbing a particular compound is governed by the internal surface area; the greater the surface area, the greater the dynamic capacity.
3. Rate of adsorption and sharpness of resolution are dependent chiefly on particle size and column packing; a fine particle size gives optimum sharpness of resolution.
4. Liquids are most readily adsorbed from solvents in which they are least soluble; a good solvent makes a good desorbing agent.
5. Highly polar liquids are readily adsorbed. Compounds having hydroxyl groups, or containing oxygen are strongly adsorbed.
6. For similar compounds, the higher the molecular weight the higher the selectivity.
7. For hydrocarbons of similar molecular weight, adsorptivity increases with the number of double bonds.
Regeneration or Activation:
A saturated molecular sieve can be restored to its original capacity by regeneration, the principle of which involves changing the conditions surrounding the adsorbent to correspond to a very low equilibrium capacity. In general, the greater the difference between the equilibrium capacities of adsorption and regeneration, the more rapid and complete the regeneration.
The sieve may be regenerated in one of four ways:
1. Thermal reactivation –The maximum regeneration temperature for Silica is 300℃.
2. Pressure reactivation
3. Passing an appropriate fluid through the gel bed at normal temperature and pressure.
4. Displacement of adsorbates by passing a high concentration of molecules in a fluid through the bed.
