硝甲酚汞不溶于水而溶于碱溶液。为此我们将它制成硝甲酚汞钠盐溶液,用于皮肤粘膜消毒。为控制其 pH 值,避免对皮肤粘膜增加刺激性,拟定处方如下:硝甲酚汞0.2g、0.1N Na OH20ml、蒸溜水加至1000ml。制得的溶液,pH 约为8.5。经三年多临床使用,效果尚好。 Nitrocresol Mercury insoluble in water and soluble in alkali solution. To this end we made it into sodium nitrocefin mercury salt solution for skin and mucous membrane disinfection. In order to control its pH and avoid irritation to the mucous membrane of the skin, the formulation prescription is as follows: 0.2 g of nitrochlorphenol mercury, 20 ml of 0.1N NaOH and distilled water to 1000 ml. The resulting solution has a pH of about 8.5. After more than three years of clinical use, the effect is still good.
