The oxidative reaction: benzyl alcohol-benzaldehyde-benzoic acid was investigated in time in aqueous solutions of benzyl alcohol widely used as a preservative in medicine and cosmetology. The solutions of benzyl alcohol were stored at concentrations from 0.005 to 2.09 mg/ml for a long time under different conditions. The presence of benzaldehyde and benzoic acid in these solutions was controlled by liquid chromatography on silica sorbent in water. The content of benzoic acid and potentially toxic benzaldehyde in solutions depending on the initial concentration of benzyl alcohol, on time, and on storage conditions was evaluated quantitatively.
研究了氧化反应
苯甲醇-苯甲醛-苯甲酸，该反应在医学和美容领域广泛用作防腐剂的苯甲醇水溶液中随时间变化的情况。苯甲醇溶液在不同条件下长时间以0.005至2.09毫克/毫升的浓度储存。通过在水中硅胶吸附剂上的液相色谱法控制这些溶液中苯甲醛和苯甲酸的存在。定量评估了溶液中苯甲酸和潜在有毒的苯甲醛的含量与苯甲醇初始浓度、时间和储存条件的关系。
