Improved Synthesis Of Succinimides And Quaternary Ammonium Ions For Use In Making Molecular Sieves

摘要

The present invention relates to the synthesis of succinimides, in particular to a method for the synthesis of a succinimide compound, comprising the step of reacting an alkyne, with carbon monoxide and ammonia or an amine, in the presence of an iron catalyst, wherein the reaction is carried out in an amine liquid phase and/or in the absence of an ether solvent. The succinimides may be reduced to quaternary ammonium cations which may be used as structure directing agents in the synthesis of molecular sieves.

1. A method for the synthesis of a succinimide compound, comprising the step of reacting (a) an alkyne, with (b) carbon monoxide and (c) an amine reagent, which is either ammonia or a primary amine, in the presence of (d) an iron catalyst and, optionally, (e) a tertiary amine solvent, under conditions in which a liquid phase is present, wherein at least one of the following criteria are met: (i) at least 50% by volume of the liquid phase is amines including any primary amine reagent and optional tertiary amine solvent, and (ii) the reaction step is carried out in the absence of ether solvents or, if ether solvents are present, the molar ratio of ether solvents to amines is no more than 1:1 and the molar ratio of ether solvents to alkyne starting materials is no more than 1:1.
