The solubility of cinnamyl alcohol in 11 pure solvents (methanol, ethanol, n-propanol, isopropyl alcohol, n-butyl alcohol, isobutyl alcohol, sec-butyl alcohol, acetone, methyl acetate, ethyl acetate and n-hexane) and two binary solvents of n-hexane + (n-propanol, n-butyl alcohol) was measured by a gravimetric method over temperatures from 253.15 K to 293.15 K at atmosphere pressure. From the experimental results, it was found that the solubility increased with the increasing temperature in all these solvents. The Apelblat model, the λh model, and the nonrandom two-liquid (NRTL) model were used to correlate the solubility data of cinnamyl alcohol in pure and mixed solvents. The thermodynamic properties of the mixing process in binary solvents were calculated by the NRTL model. The result indicates that the mixing process of cinnamyl alcohol is endothermic and spontaneous. The experimental solubility provides good guidance for the subsequent study of crystallization design and crystal morphology of cinnamyl alcohol.

反式肉桂醇在253.15 K至293.15 K纯溶剂和二元溶剂中的溶解度和热力学性质的测定和相关性

肉桂醇在11种纯溶剂（甲醇，乙醇，溶解度Ñ丙醇，异丙醇，Ñ丁基醇，异丁醇，仲-丁基醇，丙酮，乙酸甲酯，乙酸乙酯和Ñ己烷）和两个二进制溶剂的ñ己烷+（ñ丙醇，ñ丁基醇）中的溶液通过在温度重量法在大气压下测得的从253.15 K至293.15ķ。从实验结果发现，在所有这些溶剂中，溶解度都随着温度的升高而增加。该Apelblat模型，λ ħ模型和非随机两液（NRTL）模型用于关联肉桂醇在纯溶剂和混合溶剂中的溶解度数据。通过NRTL模型计算在二元溶剂中混合过程的热力学性质。结果表明肉桂醇的混合过程是吸热的和自发的。实验溶解度为肉桂醇的结晶设计和晶体形态的后续研究提供了很好的指导。
