Abstract

The use of 3-[3-(dimethylamino)propyl]-propionamide (Formula I) and 3,3′-{[3-(dimethylamino)propyl]imino}bis-propanamide (Formula II) as catalysts in the production of polyurethanes. The use of 3-{[ 3 -( dimethylamino ) propyl]amino} - propionamide ( Formula I ) and 3,3′ -{[ 3 -( dimethylamino ) propyl]imino}bis - propanamide ( Formula II ) as catalysts in the production of polyurethanes.

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
       1. A method for preparing a polyurethane comprising reacting an organic polyisocyanate with a compound containing a reactive hydrogen in the presence of a catalyst composition comprising a compound selected from the group consisting of 3-[3-(dimethylamino)propyl]-propionamide, 3,3′-{[3-(dimethylamino)propyl]imino}bis-propanamide, and combinations of 3-[3-(dimethylamino)propyl]-propionamide and 3,3′-{[3-(dimethylamino)propyl]imino}bis-propanamide. 
     
     
       2. The method of  claim 1  wherein the compound containing a reactive hydrogen is a polyol. 
     
     
       3. The method of  claim 1  wherein the catalyst composition comprises 3-[3-(dimethylamino)propyl]-propionamide. 
     
     
       4. The method of  claim 1  wherein the catalyst composition comprises 3,3′-{[3-(dimethylamino)-propyl]imino}bis-propanamide. 
     
     
       5. The method for preparing a polyurethane foam comprising reacting an organic polyisocyanate with a polyol in the presence of a blowing agent and a catalyst composition comprising a compound selected from the group consisting of 3-[3-(dimethylamino)propyl]-propionamide, 3,3′-{[3-(dimethylamino)propyl]imino}bis-propanamide, and combinations of 3-[3-(dimethylamino)propyl]-propionamide and 3,3′-{[3-(dimethylamino)propyl]imino}bis-propanamide. 
     
     
       6. The method of  claim 5  wherein the blowing agent is water. 
     
     
       7. The method of  claim 6  wherein the compound is 3-[3-(dimethylamino)propyl]-propionamide. 
     
     
       8. The method of  claim 6  wherein the compound is 3,3′-{[3-(dimethylamino)-propyl]imino}bis-propanamide. 
     
     
       9. The method of  claim 6  wherein the catalyst composition also comprises a blowing catalyst. 
     
     
       10. The method of  claim 9  wherein the blowing catalyst is a bis(dimethyl-aminoethyl)ether. 
     
     
       11. A method for preparing a polyurethane comprising reacting an organic polyisocyanate with a compound containing a reactive hydrogen in the presence of a catalyst composition comprising a compound selected from the group consisting of  3 -{[   3   -( dimethylamino ) propyl]amino} - propionamide,  3 , 3 ′ -{[   3   -( dimethylamino ) propyl]imino}bis - propanamide, and combinations of  3   -{[   3   -( dimethylamino ) propyl]amino} - propionamide and  3 , 3 ′ -{[   3   -( dimethylamino ) propyl]imino}bis - propanamide.   
     
     
       12. The method of  claim 11  wherein the compound containing a reactive hydrogen is a polyol. 
     
     
       13. The method of  claim 11  wherein the catalyst composition comprises  3 -{[   3   -( dimethylamino ) propyl]amino} - propionamide.   
     
     
       14. The method of  claim 11  wherein the catalyst composition comprises  3 , 3 ′-{[   3   -( dimethylamino )- propyl]imino}bis - propanamide.   
     
     
       15. A method for preparing a polyurethane foam comprising reacting an organic polyisocyanate with a polyol in the presence of a blowing agent and a catalyst composition comprising a compound selected from the group consisting of  3 -{[   3   -( dimethylamino ) propyl]amino} - propionamide,  3 , 3 ′ -{[   3   -( dimethylamino ) propyl]imino}bis - propanamide, and combinations of  3   -{[   3   -( dimethylamino ) propyl]amino} - propionamide and  3 , 3 ′ -{[   3   -( dimethylamino ) propyl]imino}bis - propanamide.   
     
     
       16. The method of  claim 15  wherein the blowing agent is water. 
     
     
       17. The method of  claim 16  wherein the compound is  3 -{[   3   -( dimethylamino ) propyl]amino} - propionamide.   
     
     
       18. The method of  claim 16  wherein the compound is  3 , 3 ′-{[   3   -( dimethylamino ) propyl]imino}bis - propanamide.   
     
     
       19. The method of  claim 16  wherein the catalyst composition also comprises a blowing catalyst. 
     
     
       20. The method of  claim 19  wherein the blowing catalyst is a bis( dimethylaminoethyl ) ether.
