应用国产Ｈ－酸和水杨醛合成了甲亚胺－Ｈ，并将自制甲亚胺－Ｈ与进口产品在吸收光谱特性、测 定范围、稳定时间、精密度以及实际样品的分析等方面作了比较。试验结果表明自制甲亚胺－Ｈ不仅其主 要性质与进口甲亚胺－Ｈ完全一样，而且在某些方面如水溶性等甚至更优。因此，自制甲亚胺－Ｈ完全可 以替代进口产品。由于其价格低，产率高，在发展中国家可广泛用于硼的测定。
Azomethine-H was synthesized by using H-acid and salicylaldehyde, and the properties of the prepared azomethine-H and imported products in terms of absorption spectra, measuring range, stability time, precision and analysis of actual samples Compare The test results show that not only the main properties of the self-made azomethine-H are the same as those of the imported azomethine-H, but even better in certain aspects such as water solubility. Therefore, self-made azomethine-H can completely replace imported products. Due to its low price and high yield, it can be widely used in the determination of boron in developing countries.
