The mode of OH- band and the intensity decrease linearly with the increase of pressure, i.e., y=-0.3402 x+3617.8 and R2=0.9662, and the mode disappears at 18 GPa, which is assumed to be the maximum pressure for the dehydration of phengite at room temperature.

羟基3618cm^-1谱峰则随压力增加向低频方向移动，谱峰的降低与压力的增加呈明显的线性关系变化（y=-0.3402X＋3617.8，R^2=0.9662），并且强度随着压力的增加也在逐渐减弱，在压力达18GPa时开始消失，推测该压力可能为多硅白云母在常温下脱羟基的极限压力。

Using phenylamine and acetic acid as raw materials,cyclohexane and toluene-p-sulfonic acid as dehydration and catalyst respectively.

"Half-water-hydrolysis"method is used to modify the preaminolysis of phenylenediamine in"step coupling polymerization". First, dehydrochlorination polycondensation between Si-OH and Si-Cl group during polycondensation reaction is employed instead of dehydration reaction between Si-OH groups before, which avoids the disconnection of Si-N bond destreyed by isolated water and improves the H-bonding template effect of the bridged-phenylenediamine.

探索用&半水水解-脱氯化氢缩聚&法对我组过去提出的&全水水解法&的预胺解法加以改进，经&半水水解&得到的含硅羟基和硅氯基的单体再以脱氯化氢代替脱水的方法减少了极性溶剂存在下游离水断裂梯撑模板的硅-氮键的可能性，有效地提高了对苯二胺梯撑中氢键的模板作用。

Results show that protons are liberated by dehydration or dehydroxylation after calcination at 500℃. These protons disrupt the silicon-oxygen-aluminium bridges where there are Al substitutions in the tetrahedral sheet of the montmorillonite. Some of silicon-oxygen and aluminum-oxygen tetrahedral invert to react with the pillaring agents and yield covalent bonds which firmly fix the pillars to the host clay. The Al-MMT are thermally and hydrothermally stable up to 700℃.

经过500℃高温焙烧后，交联剂经脱水或脱羟基释放出质子攻击蒙脱土四面体层中Si-O-Al四键，硅氧四面体和铝氧四面体发生翻转，与交联剂发生反应生成共价键，形成稳定的层柱黏土材料，在700℃高温下，Al-MMT材料不仅具有较好的热稳定性，而且具有较好的水热稳定性。

The results show that the method of drying at initial temperature of 35℃, and increasing temperature at a rate of 5℃/h to 60℃, keeping the temperature at 60℃ for one hour, then decreasing the temperature to 50℃, is favorable for the dehydration and color protection of Pleurotus eryngiu.

研究结果显示，采用始温35℃，以5℃/h的速度升温，至60℃条件下保持1 h，再逐渐降温至50℃的干制方法有利于杏鲍菇的脱水以及色泽的保持。
