nitrobenzene उदाहरण वाक्य
उदाहरण वाक्य
- It is mainly used as a precursor to 1, 2-dichloro-4-nitrobenzene, an intermediate in the synthesis of agrochemicals.
- Other ingredients included glycerin, nitrate, sulfuric acid, and minute concentrations of nitrobenzene, silver azide ( silver trinitride ), and liquid acetone.
- Since the above synthetic route does not efficiently produce the 3-isomer, the route most commonly used by chemists is the chlorination of nitrobenzene.
- For example, indigo is described as " insoluble in water, alcohol, or ether but soluble in chloroform, nitrobenzene, or concentrated sulfuric acid ".
- The directing effect of the nitro group of nitrobenzene leads to 93 % of the product resulting from nitration at the " meta "-position.
- Purification of 3-nitrochlorobenzene is somewhat difficult since other isomers are formed even via chlorination of nitrobenzene, and all of these isomers have similar physical properties.
- The nitrobenzene level doubled on November 25 ( 0.5805 mg / L ), 33.15 times the national safety level, and began to decrease.
- It was provided in the form of permeable cartridges of the chlorate, which were placed in wire baskets and dipped in the nitrobenzene for a few seconds before use.
- The first Raman laser, realized in 1962, used nitrobenzene as the gain medium, which was intra-cavity-pumped inside a Q-switching ruby laser.
- The reaction conditions for the Pictet Hubert reaction were improved by Morgan and Walls in 1931, replacing the metal by phosphorus oxychloride and using nitrobenzene as a reaction solvent.
