Pure solvents are obtained by

Pure solvents are obtained by distillation. Distillation is a process that involves heating a liquid mixture to vaporize the most volatile component and then cooling the vapor back into liquid form. This process allows for the separation of the components in the mixture based on their boiling points. As the most volatile component evaporates first, it can be collected separately and will have a higher degree of purity than the original mixture. Therefore, distillation is a common method used to obtain pure solvents from a mixture of liquids.
