Abstract
Official abstract text for this publication.
Novel 1-oxa-4-azonium cyclohexane salts are described. These compounds can be used as structure directing agents, and they overcome many of the typical problems associated with OSDA synthesis and subsequent zeolite synthesis. Methods for synthesis of the 1-oxa-4-azonium cyclohexane salts from a variety of starting materials are also described. A substituted hydrocarbon is added to water to form a mixture, and a 1-oxa-4-azacyclohexane derivative is then added. The reaction mixture stirred until a solution containing the 1-oxa-4-azonium cyclohexane salt is obtained.
First claim
Opening claim text (preview).
The invention claimed is: 1. A morpholinium compound comprising a 1-oxa-4-azonium cyclohexane salt having a structure of: wherein R 1 -R 8 are independently selected from H or an alkyl group having the formula C n H 2n+1 , R 9 is C 2 H 5 , where n is in the range from 1 to 4, X is halide or hydroxide, the total number of C atoms in the molecule is in the range of 11 to 24, and R 10 is an alkyl group having the formula C m H 2m , where m is in the range from 3 to 8 and is connected to the 4 and 4′ N atoms at positions x and y of the alkyl chain where x and y are independently selected from 1 to m; with the proviso that: when R 1 -R 8 are H, R 9 is C 2 H 5 , R 10 is C 6 H 12 , x is 1, and y is 6, X is hydroxide. 2. The morpholinium compound of claim 1 wherein X is hydroxide. 3. The morpholinium compound of claim 1 wherein R 1 -R 8 are H. 4. The morpholinium compound of claim 1 wherein x is 1, and y is m. 5. The morpholinium compound of claim 1 wherein when R 9 is an alkyl group and X is hydroxide. 6. The morpholinium compound of claim 1 wherein R 9 is an alkyl group and n is 1, m is 4, x is 1, and y is 4.
