摘要： Expanded amorphous aluminum silicate (EAAS) is used as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO2) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbially contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO2 release is very slow and over an extended period.

摘要： An important and central aspect of the present invention is the use of expanded amorphous aluminum silicate (EAAS) as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO.sub.2) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbally contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield chlorine dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO.sub.2 release is very slow and over an extended period. Under most conditions, a more rapid release of ClO.sub.2 is desired for deodorization and/or sterilization. A more rapid release of chlorine dioxide may be accomplished by first treating the native EAAS with an acid, preferably a protic acid, to acidify chemical groups of the EAAS. After native EAAS is acidified and dried, if necessary, a chlorite salt such as sodium chlorite is incorporated therein.
摘要翻译：本发明的重要和中心方面是使用膨胀的无定形硅酸铝（EAAS）作为亚氯酸盐的载体。这种载体在暴露于潮气时会释放二氧化氯（ClO2），以进行除臭或微生物抑制。因此，如果特定区域或体积要被除臭或者被微小污染，EAAS-亚氯酸盐（最优选亚氯酸钠）被放置在待处理的区域或体积中，并允许水分与材料相互作用。水分的结果是允许亚氯酸盐的化学反应（可能是酸化）产生二氧化氯气体。虽然正常的EAAS具有一些固有的酸性，但其固有的酸度足够低，因此即使将氯化物盐包封在EAAS中并且所得混合物暴露于潮湿环境中，ClO 2的释放也非常缓慢并且持续了很长时间。在大多数条件下，除臭和/或灭菌需要更快速地释放ClO 2。可以通过首先用酸（优选质子酸）处理天然EAAS来酸化EAAS的化学基团来实现二氧化氯的更快速释放。将天然EAAS酸化并干燥后，如果需要，可以加入亚氯酸盐如亚氯酸钠。
