摘要： A method of removing water from a mixture of iodine (I2) and water includes providing a mixture comprising iodine and water and: contacting the mixture with an adsorbent to selectively adsorb water from the mixture, contacting the mixture with a concentrated acid to absorb water from the mixture, separating the water from mixture by distillation, contacting the mixture with a gas that is inert to iodine (I2), contacting the mixture with hydrogen iodide (HI), or combinations thereof.

摘要： The present disclosure provides separation processes for removing heavy organics that are formed in various production processes of HCFO-1233zd(E). Such separation processes allow for the recovery and/or separation of the heavy organics from reactants that are used to form HCFO-1233zd(E), including HF. Such separation or recovery processes may utilize various separation techniques (e.g., decanting, liquid-liquid separation, distillation, and flash distillation) and may also utilize the unique properties of azeotropic or azeotrope-like compositions. Recovery of the heavy organic that is substantially free from HF may allow for their use in subsequent manufacture processes or disposal.

摘要： Heterogeneous azeotrope or azeotrope-like compositions comprising trifluoroiodomethane (CF3I) and water which may include from about 47.7 wt. % to about 99.0 wt. % trifluoroiodomethane (CF3I) and from about 1.0 wt. % to about 52.3 wt. % water and having a boiling point between about 18.0° C. and about 19.0° C. at a pressure of between about 58.0 psia and about 60.0 psia. The azeotrope or azeotrope-like compositions may be used to separate impurities from trifluoroiodomethane (CF3I).

摘要： Methods of recovering iodine (I2) from a stream including iodine (I2) vapor and at least one of: an inert gas and water vapor can include contacting the stream with an alkaline solution to form an iodide salt, contacting the stream with an adsorbent to selectively adsorb water from the stream, contacting the stream with a concentrated acid to absorb the water vapor from the stream, desublimating or condensing the iodine (I2) vapor to form solid or liquid iodine (I2), or contacting the stream with a material to condense or de-sublimate the iodine (I2) vapor from the stream as the material at least one of: absorbs latent heat through a phase change of the material and absorbs sensible heat.

摘要： A method of removing water from a mixture of hydrogen iodide (HI) and water includes providing a mixture comprising hydrogen iodide and water and contacting the mixture with an adsorbent to selectively adsorb water from the mixture, contacting the mixture with a weak acid to absorb water from the mixture and/or separating the water from hydrogen iodide (HI) by azeotropic distillation to produce anhydrous hydrogen iodide (HI).
