详细考察了ＳｉＭＣＭ－４１、ＡｌＭＣＭ－４１和ＨＡｌＭＣＭ－４１在不同环境中的水解和结构破坏情况．空气和水蒸汽中短期高温焙烧对全硅型ＳｉＭＣＭ－４１的结构影响较小，但在潮湿空气中长期放置可因Ｓｉ—Ｏ—Ｓｉ键发生水解而造成结构的严重破坏．ＡｌＭＣＭ－４１的抗水解能力优于ＳｉＭＣＭ－４１的，但因其结构中包含一定量的Ｎａ＋离子，降低了高温焙烧时结构的热稳定性和水热稳定性．ＨＡｌＭＣＭ－４１的热稳定性和水热稳定性均优于ＡｌＭＣＭ－４１．分子筛水热晶化过程中的盐析效应被证实是导致ＡｌＭＣＭ－４１和ＨＡｌＭＣＭ－４１抗水解能力增强的原因，因此在合成原料中加盐可显著改善ＭＣＭ－４１分子筛的抗水解能力和稳定性
The hydrolysis and structural damage of SiMCM-41, AlMCM-41 and HAlMCM-41 in different environments were investigated in detail. Short-term high temperature roasting of air and water vapor has little effect on the structure of SiMCM-41, but long-term deposition in moist air can cause serious structural damage due to hydrolysis of Si-O-Si bonds. AlMCM-41 has better hydrolysis resistance than SiMCM-41, but its structure contains a certain amount of Na + ions, which reduces the thermal stability and hydrothermal stability of the structure at high temperature. HAlMCM-41 thermal stability and hydrothermal stability are better than AlMCM-41. The salting-out effect during hydrothermal crystallization of molecular sieves has been shown to be responsible for the increased hydrolytic resistance of AlMCM-41 and HAlMCM-41, so adding salt to the synthetic feedstock can significantly improve the hydrolysis resistance and stability of the MCM-41 zeolite
