For salicylic acid,the para-selectivity is nearly 100%,but for phenol, 2-methylphenol,2-chlorophenol and 2-fluorphenol,the ortho-selectivity is observed. The textural properties of PMAV3/ SiO2are close to that of PMAV3,but BET of the supported catalysts is decreased with the rise of PMAV3...
A GREEN CHEMICAL APPROACH FOR NITRATION OF AROMATIC COMPOUNDS.aromaticecofriendlyphenolphotochemical nitrationsalicylic acidPhotochemical aromatic nitration of phenol and salicylic acid has been carried out in the presence of UV radiations and formation of products has been observed spectrophotometrically. The...
The nitration method uses a lower concentration of nitric acid as the nitrating agent, which is more economic and safer in production. The catalyst is easy to obtain, at the same time the carriers such as KSF and so on can be reused in the reaction, and the recovery is convenient. The ...
Salicylic acidTubular reactorA 2D non-isothermal reaction engineering model for a tubular reactor was developed for a complex reaction network of salicylic acid nitration. The influence of different operating and design parameters was studied to minimize the amount of secondary nitration products and ...
