How to Save the Pharmaceutical Intermediate Body Fluoribly?
May 13, 2020. Pharmaceutical intermediate body fluorine customized. Pharmaceutical fluorine: colorless liquid. The melting point -42 ℃. Boiling point 85 ° C. Refractive index (ND20) 1.4650. Relators (D420) 1.024. Insuvenate in water and mixes with ethanol, ether, acetone, and benzene. Apineine reacts through Schiemann (G. Schiemann).
Ah. After the aniline was descended to -8 ° C after 31%hydrochloride, and the sodium nitrite solution was nitroded. Cool the heavy nitrogen solution to -10 ° C, add a fluoropromic acid solution, and generate a fluoroporite salt salt with less dissolved degrees, and filter. Dry the fluoroprobenzenzene after drying. At the same time, the generated fluorine, the distilled liquid was washed with a sodium hydroxide solution, and then washed with water. After drying, it was distilled, that is, the finished product was obtained, and the income was about 53%. This method consumes a lot of boric acid, has a lot of exhaust gas, and costs high.
Storage method
Storage precautions are stored in a cool and ventilated warehouse. Stay away from fire and heat. Kuken should not exceed 37 ° C. Keep the container seal. should be kept away from oxidizer, do not store together. Explosion -proof lighting and ventilation facilities. It is forbidden to use machinery and tools that are prone to sparks. The storage area should have leakage emergency treatment equipment and suitable containment materials.
This product is mainly used to control the main raw materials such as Fluorus, Daro cytopylene, triaselopyrine, triomorinerine, pentramido, and pyrone-cyclopenon star. At the same time, it is also used for the identification of pesticide pesticides and egg -killing agents and plastic and resin polymers. Fluoropen and γ-chlorobitoboba-chloride can be made to obtain γ-chlorobenonone, which is used to synthesize fluoropyraidol. It is the most commonly used drug in psychotropic drugs in psychotropic drugs.
