摘要： The invention relates to the production of purified 1,1,1,3,3-pentafluorobutane (HFC-365mfc) comprising a reduced content of hydrogen chloride, hydrogen fluoride or unsaturated impurities. To this end, the material to be purified is treated in the liquid phase with a solid, inorganic sorption agent or with diatomic molecules which add to C-C-multiple bonds. The product to be purified is preferably treated with elemental fluorine. The content of hydrogen fluoride and hydrogen chloride can be reduced to below 1 ppm. The content of unsaturated (chlorine)-fluorine-compounds can be reduced to below 20 ppm, and the content of unsaturated C2-compounds can be reduced to below 10 ppm. It has also been discovered that fluorotrichloroethylene can be used as a control substance when monitoring the purification of 1,1,1,3,3-pentafluorobutane.

摘要： A method and apparatus for purifying hydrofluoric acid, comprising the steps of filtering the hydrofluoric acid to remove particulates (30), passing the filtered acid through a cation exchange material (14) and an anion exchange material (20) to remove ions therefrom, periodically monitoring (42) the acid that has passed through the cation exchange material for a level of cationic impurity representative of actual or impending ionic breakthrough in the cation exchange material, periodically monitoring (44, 46) the acid that has passed through the anion exchange material for a level of impurity representative of ionic breakthrough in the anion exchange material, interrupting the flow of acid at or prior to breakthrough and regenerating the anionic or cationic exchange material.

摘要： PURPOSE: A separation and recovery method separating hydrogen fluoride from fluorine-containing compound is provided to substantially separate and recover hydrogen fluoride harmful to a human body and the environment due to a high separation and recovery rate of hydrogen fluoride, thereby securing the safety of a future landfill and preventing destruction of the environment. CONSTITUTION: A separation and recovery method separating hydrogen fluoride from a fluorine-containing compound comprises the following steps. A by-product which is generated after disintegrating a fluorine-containing compound into supercritical water is contacted with an absorber, and only hydrogen fluoride is firstly separated and recovered from the by-product. The remainder hydrogen fluoride which is not separated and recovered at the previous step is secondly separated and recovered. The absorber is at least one selected from the group composed of active alumina and silica gel. An absorption liquid is at least one selected from the group composed of water and boric acid. The fluoride-containing compound is either chlorofluoro carbon or hydrochlorofluorocarbon. [Reference numerals] (AA) Removal efficiency(%); (BB) Adsorption time;

摘要： PURPOSE: A method for removing metallic ions and particulate material from an aqueous acid solution using particle removing membranes such as ultra high molecular weight polyethylene having immobilized ligand groups that possess capacity and high equilibrium binding constants for ion removal, even in acid. The method is particularly useful for simultaneously filtering/purifying aqueous acids, such as hydrofluoric or hydrochloric acid. CONSTITUTION: The process for removing metallic ions and optionally particulate material from an aqueous acid solution comprises the steps of (i) contacting the solution with a composition suitable for removing metallic ions and optional particulate material contained in the solution; (ii) recovering a purified and filtered solution essentially depleted of metallic ions and optional particulate material, wherein the composition comprises a membrane ligand combination represented by the formula: M-B-L wherein M is a membrane or composite membrane having a hydrophilic or partially hydrophilic surface and containing polar functional groups; L is a ligand having an affinity for metallic ions and containing a functional group reactive with an activated polar group from the membrane; and B is a covalent linkage formed by the reaction between the activated polar group and the functional group of the ligand.
