Process for the reaction of a solution containing a mixture |
摘要 |
<p>A method for reacting a solution containing a mixture of at least two chemicals in chemical equilibrium with other chemical(s) involves: (a) separating the solution into at least two fractions, enriched in the various compounds relative to the equilibrium concentrations; and (b) reacting one fraction with the other reactant(s) before equilibrium is completely restored. A method for reacting a solution containing a mixture of at least two chemicals in chemical equilibrium with other chemical(s) involves: (1) separating the solution into at least two fractions, enriched in the various compounds relative to the equilibrium concentrations; and (2) reacting one fraction with the other reactant(s) before equilibrium is completely restored. Excluded is the reaction of a formaldehyde solution, containing polyoxymethylene glycols and optionally monomeric formaldehyde and/or methylene glycol, with aniline in presence of an acid catalyst.</p> |
