Abstract

Embodiments described herein provide a compound that may be used in a variety of applications such as corrosion inhibition, additives for metalworking, mining reagents, epoxy curatives, emulsifiers, fuel or lubricant additives, surfactant manufacture, acid scavengers and asphalt additives. The compound has the following structure: where R 1 is a methoxy group, R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group, and R 6 is an aminomethyl group.

Claims (40)

1. A compound having the structure:

wherein R 1 is a hydrogen atom or a methoxy group,

R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group, and

R 6 is a nitrile group or an aminomethyl group.

2. The compound of claim 1 , wherein the compound has the structure:

3. The compound of claim 1 , wherein the compound has the structure:

4. The compound of claim 1 , wherein the compound has the structure:

5. The compound of claim 1 , wherein the compound has the structure:

6. An etheramine compound having the structure:

wherein R 6 has the structure

R 7 is a hydrogen atom or the same as R 6 ,

R 1 is a hydrogen atom or a methoxy group, and

R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group.

7. The etheramine compound of claim 6 , wherein the etheramine compound has the structure:

8. The etheramine compound of claim 6 , wherein the etheramine compound has the structure:

9. The etheramine compound of claim 6 , wherein the etheramine compound has the structure:

10. A method for forming an etheramine compound, comprising:

reacting 4-methylcyclohexane methanol or 4-methoxymethylcyclohexane methanol with an alkene having a nitrile group to form an intermediate compound having the structure:

wherein R 1 is a hydrogen atom or a methoxy group and R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group; and

hydrogenating the intermediate compound to form the etheramine compound having the structure:

wherein R 1 is a hydrogen atom or a methoxy group and R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group.

11. The method of claim 10 , wherein the alkene having the nitrile group is acrylonitrile.

12. The method of claim 10 , wherein a cobalt catalyst is used for the hydrogenating of the intermediate compound.

13. The method of claim 12 , wherein the etheramine compound has the structure:

14. An etheramine compound formed by a method comprising:

reacting 4-methylcyclohexane methanol or 4-methoxymethylcyclohexane methanol with an alkene having a nitrile group to form an intermediate compound having the structure:

wherein R 1 is a hydrogen atom or a methoxy group and R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group; and

hydrogenating the intermediate compound.

15. The etheramine compound of claim 14 , wherein the etheramine compound has the structure:

wherein R 1 is a hydrogen atom or a methoxy group and R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group.

16. The etheramine compound of claim 15 , wherein the etheramine compound has the structure:

17. A method for forming an etheramine compound comprising:

reacting 4-methylcyclohexane methanol or 4-methoxymethylcyclohexane methanol with an alkene having a nitrile group to form an intermediate compound having the structure:

wherein R 1 is a hydrogen atom or a methoxy group and R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group; and

hydrogenating the intermediate compound in the absence of ammonia using a nickel catalyst to form the etheramine compound having the structure:

wherein R 1 is a hydrogen atom or a methoxy group.

18. A method for forming an etheramine compound comprising:

reacting 4-methylcyclohexane methanol with an alkene having a nitrile group to form an intermediate compound having the structure:

wherein R 1 is a hydrogen atom and R 2 , R 3 , R 4 and R 5 are independently a hydrogen atom or an alkyl group; and

hydrogenating the intermediate compound using a platinum catalyst to form the etheramine compound having the structure:
