Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

We claim: 1. A crystalline molecular sieve, which includes a structure directing agent Q within its pores; wherein the structure directing agent Q is a quaternary ammonium ion having a structure and a name selected from the group consisting of: Structure Name of cation 1-cyclohexyl-3,4-diethyl-1- methylpyrrolidin-1-ium, (3R,4R)-3,4-diethyl-1,1- dipropylpyrrolidin-1-ium + (3S,4S)-3,4-diethyl-1,1- dipropylpyrrolidin-1-ium, (3R,4R)-3,4-diethyl-1- methyl-1-propylpyrrol- idin-1-ium + (3S,4S)- 3,4-diethyl-1-methyl- 1-propylpyrrolidin-1-ium, 1-(tert-butyl)-1,3,4- trimethylpyrrolidin-1-ium, 1,1′-(butane-1,4-diyl)- bis(3,4-diethyl-1- methylpyrrolidin-1-ium), 1,1′-(butane-1,4-diyl)- bis(3,4-diethyl-1- propylpyrrolidin-1-ium), 1,1′-(pentane-1,5-diyl)- bis(3,4-diethyl-1- propylpyrrolidin-1-ium), 1,1′-(hexane-1,6-diyl)- bis(3,4-diethyl-1- propylpyrrolidin-1-ium, 1,1′-(pentane-1,5-diyl)- bis(3,4-dimethyl-1- propylpyrrolidin-1-ium), 1,1′-(hexane-1,6-diyl)- bis(1-ethyl-3,4- dimethylpyrrolidin-1-ium), 1,1′-(butane-1,4-diyl)- bis(1-ethyl-3,4- dimethylpyrrolidin-1-ium), 1,1′-(propane-1,3-diyl)- bis(1-ethyl-3,4- dimethylpyrrolidin-1-ium), 1,1′-(propane-1,3-diyl)- bis(1,3,4-triethylpyrroli- din-1-ium), and 1,1′-(butane-1,4-diyl)- bis(1,3,4-triethyl- pyrrolidin-1-ium). 2. A process for producing a crystalline molecular sieve, which includes a structure directing agent Q within its pores; said process comprising the steps of: (i) preparing a synthesis mixture capable of forming a molecular sieve, said synthesis mixture comprising a source selected from a source of a tetravalent element Y, a source of a trivalent element X, or a mixture of a source of tetravalent element Y and a source of trivalent element X, and optionally a source of pentavelent element Z, optionally a source of hydroxide ions, optionally a source of halide ions and optionally a source of alkali metal ions M + , the synthesis mixture further comprising a structure directing agent Q; (ii) heating said synthesis mixture under crystallization conditions for a time of from about 1 to about 100 days to form crystals of said molecular sieve; and (iii) recovering said crystals of said crystalline molecular sieve from said synthesis mixture, wherein said structure directing agent Q is a quaternary ammonium ion having a structure and a name selected from the group consisting of: Structure Name of cation 1 -cyclohexyl- 3,4-diethyl-1- methylpyrrolidin- 1-ium,
