利凡诺溶液的稳定性问题,据国内外报道可总括为对光敏感,易变色等。为此对利凡诺水溶液进行了抗氧、抗光解的实验研究。一般试验利凡诺水溶液为浅黄色。0.5～1%溶液的 pH 为6.3(产品为青海制药厂出品,批号7075),经热、光、氧试验结果如表1。 Rivanol solution stability problems, according to reports at home and abroad can be summarized as sensitive to light, easy to change color. To this end, Rivanol aqueous solution was subjected to the experimental study of anti-oxidation and anti-photolysis. General test Rivanol aqueous solution is light yellow. 0.5 ~ 1% solution of pH 6.3 (product manufactured by Qinghai Pharmaceutical Factory, lot number 7075), the heat, light and oxygen test results in Table 1.
