To decide which solvents and temperatures can be used in the design of new processes, trial and error is often used, as the choice is restricted by unknown solid solubility limits. Here, we present a fast and convenient computational method for estimating the solubility of solid neutral organic molecules in water and many organic solvents for a broad range of temperatures. The model is developed by combining fundamental thermodynamic equations with machine learning models for solvation free energy, solvation enthalpy, Abraham solute  \nparameters, and aqueous solid solubility at 298 K. We provide free open-source and online tools for the prediction of solid solubility limits and a curated data collection (SolProp) that includes more than 5000 experimental solid solubility values for validation of the model. The model predictions are accurate for aqueous systems and for a huge range of organic solvents up to 550 K or higher. Methods to further improve solid solubility predictions by providing experimental data on the solute of interest in another solvent, or on the solute’s sublimation enthalpy, are also presented.  \n■ INTRODUCTION  \nThe solubility of solids in organic solvents plays a huge role in various chemical systems such as organic chemistry, environmental chemistry, organo(photo)catalysis, and (petro) -chemical industry. Solid−solution equilibria are, for example, used in the design of flow batteries, purification units, extraction units, and liquid-phase chemical processes. Specific to the pharmaceutical industry, the solubility of active pharmaceutical ingredients (API) in a variety of organic solvents is an important property in the development of new drugs. Many curated databases (e.g., the AqSol database 1) are available for the aqueous solid solubility of APIs as this property is of interest in the initial screening process of potential drugs. Further in the drug development chain during lab-scale synthesis, purification, crystallization, and scale-up from batch to continuous processes, information on the solubility of the APIs in organic solvents other than water is required.  \nMany methods exist for the prediction of the solubility of solids in specific organic solvents. A recently published review by Kuentz et al.2 summarizes recent advances in solubility predictions. The main limitation of existing methods is that they require physical properties of the solute, such as the  \nfusion known in the  \nenthalpy and/or melting temperature (e.g., the wellNRTL method3) or empirical solute parameters (e.g., relationships developed by Abraham et al.4). Other  \nmethods for the direct prediction of solid solubility are always  \nlimited to one or a few solvents. For example, the aqueous solid solubility is important in many applications, including the initial screening of potential APIs, and thus there are enough data available to train deep neural networks for the prediction of this property. Some examples of recent successful datadriven predictors for the aqueous solid solubility are AquaSol developed by Lusci et al.,5 the models of Cui et al.6 and by Boobier et al.,7 and SolTranNet developed by Francoeur and Koes.8 Despite the tremendous progress made in machine learning for molecular and material science,9 for the direct prediction of ","cbCaikyESJU0QmM5","https://ap.wps.com/l/cbCaikyESJU0QmM5","pdf",1797269,13,"English","# Abstract\n# Introduction","[{\"question\":\"Why are predicting solid solubility limits important in process design?\",\"answer\":\"Solid solubility limits restrict which solvents and temperatures can be used, affecting phase separation, purification, and migration of species into the environment.
