Title: Fullerenol production method
Inventor: Teryaev Andrej Sergeevich
IPC: B82Y40/00
Filed: 2020-02-17
Granted: 2021-06-29
Abstract: FIELD: chemical industry.SUBSTANCE: invention relates to the chemical industry. First, fullerene C60 with purity of 97-99% is mixed with sodium hydroxide in a ratio of 1:20 and the resulting mixture is combined with hydrogen peroxide until the reaction stops. The reacted mixture is heated to 80±5°C. It is stirred until it is evaporated to a pasty state at the rate of 18-20 hours for every 100 ml of hydrogen peroxide. Distilled water is added to the resulting pasty mass at the rate of 900 ml per 1 g of the original fullerene. After that, the solution is neutralized with hydrochloric acid to a pH of 9.00 - 0.05. Anhydrous calcium chloride is added to the neutralized solution, heated to 95±5°C, cooled to room temperature, settled and filtered through a blue ribbon-type paper filter located in a Buchner funnel or Wurtz flask. Re-filtration can be carried out through a conical funnel. The product remaining on the filter is rinsed with acetone, removed for drying, dried and treated with sulfuric, hydrochloric or nitric acid to obtain fullerenol. The method can be implemented on an industrial scale on the basis of specialized chemical-technological laboratories.EFFECT: manufacturability of fullerenol synthesis is enhanced by increasing productivity and reducing the number of technological operations while maintaining the quality of the target product.6 cl

Granted: 2020-12-07
Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to diving medicine, and can be used for prevention of decompression sickness. Laboratory animal is placed in a pressure chamber and further air pressure is increased inside the pressure chamber. Excess pressure in the chamber is raised to 7.5–8.2 kg/cm 2  by feeding compressed air at speed of 4.0–4.5 kgf/cm 2  per minute, kept under this pressure animal 30 ± 2 minutes. Then, the gas medium of the pressure chamber is replaced for 10–20 seconds with a perfluorocarbon respiratory fluid which is free of metabolically indifferent gas, while maintaining excess pressure in the pressure chamber of 7.5–8.2 kgf/cm 2 . After that the animal was kept on a separate liquid breathing for 30–35 minutes, and more incessantly and quickly reduce the pressure in the chamber at rate of 10–16 kgf/cm 2  per minute to the normal atmospheric pressure. Thereafter, the animal is removed from the respiratory fluid and switched to independent breathing with air at normal atmospheric pressure. 
     EFFECT: method enables preventing caisson (decompression) disease at excessively high decompression rates (emergency depressurization, "explosive" decompression, ejection from depth) and individual bioreflectivity of the intravascular gas formation without negative side effects from the use of the pharmacological preparations by removing the metabolically indifferent gases from the body by liquid breathing before beginning of medium pressure increase (under normal-baric conditions) or during stay under excessive pressure (in hyperbaric conditions).
