The data presented in this article are related to the research article entitled "RH-temperature phase diagrams of hydrate forming deliquescent crystalline ingredients" (Allan and Mauer, 2017) [1]. The data are water activity measurements of alcohol:water solutions (methanol:water and ethanol:water solutions at varying molar ratios) at different temperatures collected using the Tunable Diode Laser by Decagon Devices. The measured water activities of ethanol:water solutions were correlated to the initial volumetric ratios to produce polynomial equations that can be used to calculate the needed initial volumetric ratios for water activity controlled solutions. The data sets and polynomial equations are provided to enable extended analyses and applications of the data and calculations for generating and using controlled water activity solutions containing alcohol. An example application of these data is described in the research article mentioned above.
本文所呈现的数据与题为《水合物形成潮解性晶体成分的相对湿度 - 温度相图》（艾伦和莫尔，2017年）[1]的研究论文相关。这些数据是使用Decagon Devices公司的可调谐二极管激光器在不同温度下对酒精与水的溶液（不同摩尔比的甲醇与水溶液和乙醇与水溶液）进行的水分活度测量值。所测得的乙醇与水溶液的水分活度与初始体积比相关联，以生成多项式方程，这些方程可用于计算水分活度受控溶液所需的初始体积比。提供数据集和多项式方程是为了能够对数据进行扩展分析和应用，并进行相关计算，以生成和使用含酒精的受控水分活度溶液。上述研究论文中描述了这些数据的一个示例应用。
