在对现有的大规模脱酸工艺进行概述并声明它们都不满足构成“理想”的条件之后，定义了这些条件：将pH值提高到约1.5。7.5、产生碱性储备、不显著降低机械强度、不改变文件的光学性质、不引起油墨和颜色的渗色等。由于含氮有机化合物可能满足这些条件，因此测试了一些这样的化合物，即一些硅氮烷和一些硅烷，初步结果是，在液相中使用的氨基硅烷，可能会有希望。
After an over-view on the existing mass deacidification processes and the statement that none of them fulfill the conditions that would constitute an "ideal" one, these conditions are defined: raising the pH to ca. 7.5, producing an alkaline reserve, not significantly reducing mechanical strength, not altering the optical properties of the documents, not provoking bleeding of the inks and colours, etc. As it might be possible that nitrogen containing organic compounds would fulfil these conditions, some such compounds were tested, namely some silazanes and some silanes, with the preliminary result that aminosilanes, used in a liquid phase, might be promising.
