The present invention generally relates to compositions and methods for scavenging hydrogen sulfide and/or mercaptans from fluids. More particularly, the invention relates to the use of amino acetal and ketal compounds as a hydrogen sulfide or a mercaptan scavenger for hydrocarbon fluids, particularly for natural gas, crude oil, field oil, fuel oil, naphtha, gasoline, kerosene, diesel, refinery gas, coal gas, tar, asphalt, coke gas, ammonia synthesis gas, gas from a sulfurization plant, or industrial gas streams.

1. A method of reducing the amount of hydrogen sulfide or a mercaptan in a hydrocarbon fluid comprising contacting the hydrocarbon fluid with an effective amount of a scavenger composition to reduce the amount of hydrogen sulfide or mercaptan in the hydrocarbon fluid, the scavenger composition compr
1. A method of reducing the amount of hydrogen sulfide or a mercaptan in a hydrocarbon fluid comprising contacting the hydrocarbon fluid with an effective amount of a scavenger composition to reduce the amount of hydrogen sulfide or mercaptan in the hydrocarbon fluid, the scavenger composition comprising a compound of formula 1 having the structure: wherein R1 is independently —NR3R4, —O(CH2)nNR5R6, or —OR7;R2, R3, R4, R5, and R6 are independently hydrogen, alkyl, alkenyl, or alkynyl;R7 is alkyl, alkenyl, or alkynyl;n is an integer from 1 to 10; andR2 is hydrogen when R1 is —NR3R4. 2. The method of claim 1 wherein the compound of formula 1 has the structure of formula 2 or 3: wherein R8 is independently alkyl, alkenyl, alkynyl, or —(CH2)nNR5R6. 3. The method of claim 2 wherein R3, R4, R5, R6, R7 and R8 are C1 to C20 alkyl and R2 is hydrogen or C1 to C20 alkyl. 4. The method of claim 3 wherein R3, R4, R5, R6, R7 and R8 are independently methyl, ethyl, propyl, butyl, pentyl, or hexyl. 5. The method of claim 4 wherein R8 is methyl or ethyl. 6. The method of claim 5 wherein R2 is hydrogen, methyl or ethyl. 7. The method of claim 6 wherein R3 and R4 are independently hydrogen, methyl, ethyl, propyl, or butyl. 8. The method of claim 7 wherein R5 and R6 are independently hydrogen, methyl, ethyl, propyl or butyl. 9. The method of claim 8 wherein R8 is methyl. 10. The method of claim 9 wherein R2 is hydrogen. 11. The method of claim 10 wherein R3 and R4 are methyl. 12. The method of claim 2 wherein the effective amount of the compound of formula 2 or 3 is from 5 to 10,000 ppm in the hydrocarbon fluid. 13. The method of claim 9 wherein R2 is methyl. 14. The method of claim 8 wherein R8 is ethyl. 15. The method of claim 1 wherein the scavenger composition consists essentially of or consists of the compound of Formula 1. 16. The method of claim 1 wherein the hydrocarbon fluid is a liquid. 17. The method of claim 16 wherein the liquid is crude oil, field oil, asphalt, fuel oil, naphtha, gasoline, kerosene, or diesel. 18. The method of claim 17 wherein the liquid is crude oil. 19. The method of claim 1 further comprising storing the hydrocarbon fluid in a storage tank, rail car, tank truck, or pipeline after it is contacted with the composition. 20. The method of claim 19 wherein the hydrocarbon fluid is stored in a storage tank. 21. The method of claim 20 wherein the composition is contacted with the hydrocarbon fluid by injecting the composition into the storage tank with mixing. 22. The method of claim 1 wherein the composition is contacted with the hydrocarbon fluid by injecting the composition into a run-down line for the hydrocarbon fluid.
