The synthesis method is as follows: under the action of a high-performance catalyst, p-alkoxy benzoic acid and ammonia gas are subjected to amidation to synthesize p-formylamino benzene alkyl ether through a one-step method. The method provided by the invention is mild in condition, simple in...
In the reaction nitration of benzene, benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature which is not more than 50°C. With the increase in temperature, there is are more chances of producing more than one nitro group, -NO₂, that...
3-phenyl-3-pentanol You do not have to consider stereochemistry. If more than one structure fits the des What is the major product in nitration of 4 Bromo benzoic acid ? Using resonance structures please explain the reason for this preference. Which of th...
18O-Labeled hydrogen peroxide (H218O2) was used as probe to study the incorporation of oxygen into benzene and the isotopic distribution of18O in the products. Reactions were carried out with or without ascorbic acid as phenoxyl radical scavenger and analyzed by LC-MS. Mass spectra of catecho...
Convert benzene to methyl benzene by reacting it with CH3Cl and anhydrous AlCl3.Oxidize methyl benzene with a powerful oxidizing agent like alkaline KMnO4we will get benzoic acid. How do you convert benzene to nn dimethylaniline? Hint: the benzene is nitrated followed by the reduction in presence...
The crude product is dissolved in water at 280-290 ℃ and a pressure of about 7MPa, and then hydrotreated in the presence of a catalyst to remove p-carboxyl benzoic acid, and then crystallized, filtered, washed, and dried to obtain fiber grade terephthalic acid. 2. The raw material of ...
/trans-4'-n-alkylcyclohexyl/anilines with an alkyl with 1 to 12 carbon atoms in the chain with acid chlorides /preferably thiophosgene/ or alkyl chloroformate in an organic solvent solution /preferably benzene/ in the presence of a ternary amine /preferably triethylamine/ and carbon disulphide. ...
2.Substituted benzenes in water were enriched with GDX 102 resins.本方法对十四种取代苯的加标回收率为 92 %～ 98% ,相对标准偏差在 5 %以下 ,最低检测限达 3。 3.Nowadays it is one of the difficult problems that how to evaluate the toxicity of the substituted benzenes to the environment ef...
It acts as an additive for lithium-ion battery electrolyte to enhance the battery safety. It is used to prepare intermediates such as phenol and cyclohexanone. Further, it is used in the preparation of liquid crystal display (LCD) material intermediate 4-ethyl cyclohexyl benzoic acid. View all ...
