用重量法测定了尼泊金丁酯（4-羟基苯甲酸丁酯）在甲醇、乙醇、丙醇、丙酮、乙酸乙酯和乙腈中的溶解度，温度范围为（10 - 50）C。20 ℃时，尼泊金丁酯在不同溶剂中的溶解度（质量分数）顺序为：甲醇>乙醇>丙酮>丙醇>乙酸乙酯>乙腈。在摩尔分数溶解度方面，相应的顺序是丙酮>丙醇>乙醇>乙酸乙酯>甲醇>乙腈，这表明对羟基苯甲酸酯分子的非极性和极性基团影响在不同溶剂中的溶解度。
The solubility of butyl paraben (butyl 4-hydroxybenzoate) have been determined in methanol, ethanol, propanol, acetone, ethyl acetate, and acetonitrile in the temperature range of (10 to 50) C by the gravimetric method. The order of the solubility of butyl paraben in the different solvents as mass fraction at 20 C is: methanol > ethanol > acetone > propanol > ethyl acetate > acetonitrile. In terms of mole fraction solubility, the corresponding order is acetone > propanol > ethanol > ethyl acetate > methanol > acetonitrile, which shows that both nonpolar and polar groups of the paraben molecule influence the solubility in the different solvents.
