本文作者研究了温度和浓度对悬浮液中乙酰水杨酸水解速率的影响,和在乙酰水杨酸悬浮液中添加各种附加物对稳定性的影响。以PH为3的缓冲液为溶媒,分别混悬乙酰水杨酸粉末(100号筛及60号筛),置恒温水溶中,保持温度为46,50,及60℃,每隔4小时,用分光光度法于298mμ处,作乙酰水杨酸水解速率分析。从实验得出,乙酰水杨酸水解为零级反应,悬浮液愈浓,则半衰期愈长,并水解速率
The authors studied the effect of temperature and concentration on the rate of hydrolysis of acetylsalicylic acid in suspension and the effect of adding various addenda to the suspension of acetylsalicylic acid on stability. Acetyl salicylic acid powder (sieve No. 100 and sieve No. 60) was suspended in a buffer solution of pH 3 at a constant temperature of 46, 50, and 60 ° C, respectively, for every 4 hours with Spectrophotometry at 298mμ for acetylsalicylic acid hydrolysis rate analysis. Obtained from the experiment, hydrolysis of acetylsalicylic acid to zero-order reaction, the more concentrated suspension, the longer half-life, and the hydrolysis rate
