在文献中记载过的α-萘胺测定法,是基于它重氮化作用与对-硝基苯胺相结合,或是用对-氨基苯磺酸使之重氮化,然扣与α-萘胺相结合。当空气介质中萘胺的含量很少而测定的时间较长时,该些方法对生产程序难于作出正确的卫生孛评价。现在研究的任务是根据比较灵敏的反应、简单的操作步骤和快速法进行采样而拟定一种快速的测定方法。我们不同意用0.0001N过氯酸溶液在非水介质中作微量滴定α-萘胺的方法。因为由于过氯酸能引起爆炸,并且
The a-naphthylamine assay described in the literature is based on its diazotization combined with p-nitroaniline or diazotization with p-aminobenzenesulfonic acid, Amine combination. When the naphthalene amine content in the air medium is low and the measurement time is long, these methods make it difficult to make the correct health assessment of the manufacturing process. The task now is to develop a rapid assay based on more sensitive reactions, simple procedures and rapid sampling. We disagree with the method of microtilting alpha-naphthylamine in non-aqueous media with 0.0001 N perchloric acid solution. Because of the perchloric acid can cause an explosion, and
