Способ очистки бишофита от соединений железа

FIELD: chemistry and medicine.SUBSTANCE: invention relates to the field of chemistry and medicine, specifically to methods for purifying bischofite used as an independent pharmaceutical agent, as well as for obtaining magnesium-containing medicinal compositions. Bischofite is used in many areas of industry, mainly as a raw material for the production of metallic magnesium, in addition, it is widely used in medicine in the form of compresses, rinses, baths, ointments, solutions for electrophoresis, etc. The essence of the invention lies in the use of ion-exchange sorption on a strongly acidic cation exchanger KU 2-8 for cleaning bischofite from impurities of iron compounds. At the first stage of purification, a cation exchanger saturated with magnesium ions is prepared; for this, a 10% bischofite solution is passed through a column with resin at a rate of 1 l/h using a peristaltic pump until the cation exchanger is completely saturated with magnesium ions. At the second stage, a purified 10% bischofite solution is passed through the column prepared in the above described way using a peristaltic pump at a rate of 1 l/h. The solution passed through the column is evaporated 10 times, at the end of the evaporation it is cooled to 20-30°C and the precipitated crystals of magnesium chloride hexahydrate are filtered off from the mother liquor on a vacuum filter. The wet crystals of magnesium chloride hexahydrate are dried to constant weight in a desiccator with calcium chloride.EFFECT: invention shortens the duration of the cleaning process, is not energy-consuming and has a high efficiency.1 cl, 5 tbl, 2 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 748 371 C1 (51) МПК C01F 5/30 (2006.01) C01B 9/02 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C01F 5/30 (2021.02); C01B 9/02 (2021.02) (21)(22) Заявка: 2020134770, 22.10.2020 (24) Дата начала отсчета срока действия патента: Дата регистрации: 24.05.2021 (45) ...

Recovered hydrogen chloride byproduct is contacted with oxygen and a molten salt mixture containing the higher and lower valent chlorides of a multivalent metal, such as cuprous and cupric chloride, to effect recovery of the hydrogen chloride by enriching the molten salt content of the higher valent chloride. The molten salt, enriched in higher valent chloride, is then dechlorinated by use of a stripping gas, preferably hydrogen chloride, to produce a gaseous effluent containing stripped chlorine and the stripping gas, which is then recycled to the chlorination step. The presence of stripping gas, as a diluent, improves the chlorination operation.

INNOVATIVE AND SAFE METHOD TO CONDUCT HIGH TEMPERATURE HALOGENATION OF METALLIC ALLOYS

The present invention discloses a method and system for conducting high temperature corrosion tests on metallic alloys without the need for extensive laboratory equipment and attendant safety measures through the use of a two-compartment ampoule where a vestibule connects these two compartments. A pre-selected mixture of salts is placed in one compartment in order to generate a specific partial pressure of halogen gas; and a metallic alloy is placed in the other compartment. The ampoule is then heated to a pre-determined temperature and held at this temperature for a pre-determined time period. A halogen gas of a specific partial pressure is thereby generated from the mixture of salts which comes into contact with the metallic alloy. Because the ampoule creates a sealed environment, the metallic alloy is under constant halogenation during the pre-determined time period. The metallic alloy is removed for examination when the pre-determined time period expires. 1: A method for conducting halogenation of metallic alloys comprising:providing a sealed container wherein the sealed container comprises a first compartment, a second compartment, and a channel that connects the first compartment and the second compartment wherein the channel is configured to allow gas flowing between the first and second compartments;enclosing a metallic alloy element in the first compartment;enclosing a pre-selected mixture of salts comprises nickel and nickel chloride in the second compartment;heating the sealed container to a pre-determined temperature and maintaining at the pre-determined temperature for a pre-determined time period so that the pre-selected mixture of salts generate a chlorine gas of a specific partial pressure at the pre-determined temperature;exposing the metallic alloy element to the chlorine gas that is generated from the pre-selected mixture of salts and flowing from the second compartment for the pre-determined time period;the pre-determined temperature is ...

Process and apparatus for removing Bronsted acid impurities in binary halides

A process and apparatus is provided for the purification of binary halide fluid. The process and apparatus purifies the binary halide fluid by selectively removing Bronsted acid impurities and/or volatile oxygen containing impurities present in the binary halide. A regenerable adsorbent polymer is utilized to remove the Bronsted acid impurities from the binary halide fluid and a volatile oxide adsorbent having a specific adsorption capacity for the volatile oxide impurity is utilized to remove the volatile oxide from the binary halide when in gaseous form.

Process for the preparation of ferric chloride from ferrous chloride

Solution chloride manufacturing apparatus for snow removing and method of preparing thereof

An apparatus and a method for preparing a chloride solution are provided to produce a chloride solution suitable for snow removal quickly while maintaining the small volume of the apparatus, by using a controller for controlling the quantities of chloride and water. A quick stirrer(134) mixes and stirs solid type chloride and water while a controller(150) controls the quantities of the chloride and the water. As the result, a chloride solution of which the chloride concentration is the most suitable for snow removal, is discharged. When the chloride concentration of the chloride solution deviates from a reference value, it is checked whether the solid type chloride and the water are normally supplied and the entire system is stopped.
