Abstract
Official abstract text for this publication.
The present invention provides compositions consisting of a) at least one metal salt, ammonium salt or phosphonium salt of a strong Brønsted acid and b) at least one primary aliphatic monoamine, processes for preparation thereof and use thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition consisting of a) at least one metal salt, ammonium salt or phosphonium salt of a strong Brønsted acid and b) at least one primary aliphatic monoamine. 2. The composition according to claim 1 , wherein the composition has from 10 to 95% by weight of component a) and 5-90% by weight of component b), based on the weights of components a) and b). 3. The composition according to claim 1 , wherein the at least one metal salt a) is a salt of an acid selected from the group consisting of oxalic acid, p-toluenesulfonic acid, trifluoroacetic acid, tetrafluoroboric acid, nitric acid, sulfuric acid, hydrochloric acid, hydrochloric acid, perchloric acid, trifluoromethanesulfonic acid, hydrogen iodide, hexafluorophosphoric acid and hexafluoroantimonic acid. 4. The composition according to claim 1 , wherein the Brønsted acid has a pK A not higher than −9.01. 5. The composition according to claim 1 , wherein the at least one primary aliphatic monoamine b) has exclusively aliphatic radicals having from 3 to 30 carbon atoms. 6. The composition according to claim 1 , wherein the at least one primary aliphatic monoamine b) has a boiling point, measured at 1013.25 hPa, of from 30 to 300° C. 7. The composition according to claim 1 , wherein the at least one primary aliphatic monoamine b) is selected from the group consisting of n-propylamine, isopropylamine, n-butylamine, sec butylamine, tert butylamine, n-pentylamine, n-hexylamine and ethanolamine. 8. The composition according to claim 1 , wherein the at least one metal salt a) of the strong Brønsted acid is calcium triflate, and the at least one primary aliphatic monoamine b) is n-butylamine. 9. The composition according to claim 1 , wherein the at least one metal salt a) is calcium triflate and at least one primary aliphatic monoamine b) is n-butylamine. 10. The process for preparing the composition according to claim 1 , in which a) at least one metal salt, ammonium salt or phosphonium salt of a strong Brønsted acid and b) at least one primary aliphatic monoamine are mixed with one another.
