摘要： A method for continuously carrying out, in an aqueous medium, a chemical alteration of a hydrophobic organic substance, by means of catalysis thereof in polymeric microregions using a macromolecular catalytic system which is soluble in said medium in the form of aggregate or monomolecular microglobules or the like. The method is characterized in that it takes place in a reactor comprising a filtering device which can hold onto said polymeric microregions while letting through the molecules of the reaction product or products, in that a reaction medium is placed or prepared in the reactor and comprises a solution of said macromolecular catalytic system in an aqueous medium, in that a solution of said hydrophobic substance is gradually and continuously or intermittently inserted into the reactor and can chemically react in said macromolecular catalytic system to give one or more non-hydrophobic reaction products, in that the reaction medium is simultaneously filtered so that its volume remains substantially constant, and in that the filtered liquid is recovered at the outlet of the filtering system. The method can be used particularly in hydrolysis and basic catalysis deprotection reactions.

摘要： The present invention provides a process for the nitration of aromatic substrates. In one process, an aromatic substrate is reacted with a silicate, optionally modified with a metal nitrate, in the presence of an acid anhydride and an organic solvent, followed by the addition of reduced amounts of nitric acid. Isolation of the nitrated products involves filtration, washing and solvent removal. This process can produce either mono- or polynitrated aromatic compounds depending upon the conditions selected and the aromatic substrate. The present invention also provides related processes for the nitration of strongly activated aromatic substrates using only silicates modified with metal nitrate in the presence of acid anhydrides and an organic solvent. All of these processes provide advantages in yield, cost, and safety over the industrial methods of nitration using mixed acids.

摘要： A method of nitrating resorcinol which is selective for the production of the 4,6-dinitroresorcinol isomer. A resorcinol-based starting material is admixed with a nitrating solution from which substantially all nitrogen dioxide and nitrous has been removed. The nitrating solution contains white fuming nitric acid, a nitrosonium ion control agent such as urea, and, optionally, concentrated sulfuric acid. The 4,6-dinitroresorcinol isomer is provided in yields of about 65-85 % with minimal production of undesirable side products.
