## Abstract

A method for providing a secondary or tertiary amine with formula (R1R2NR3)2NR4 is provided, wherein each of R1 and R2 are chosen from the group consisting of a methyl group, an ethyl group, an iso-propyl group and an n-propyl group; R3 being an alkoxyalkyl group chosen from the group consisting of —CH2CH2OCH2CH2-, —CH2CH2OCH2CH2- and —CH2CH2CH2OCH2CH2CH2-; R4 is chosen from the group consisting of a hydrogen, a methyl group, an ethyl group, an iso-propyl group, an n-propyl group and a group with formula R1R2NR3. The method comprises the steps: (α) reacting R1R2NR3(OH) with ammonia, thereby providing a mixture comprising (R1R2NR3)2NR4; (β) separating (R1R2NR3)2NR4 from said mixture.

## Claims

### Claim 1

A secondary amine with formula (R1R2NR3)2NH, wherein
each of R1 and R2 are a methyl group;
R3 being —CH2CH2OCC2CH2—.

### Claim 2 (depends on 1)

A secondary amine with formula (R1R2NR3)2NH according to claim 1, wherein said (R1R2NR3)2NH comprises alkylated (R1R2NR3)2NH, typically (R1R2NR3)2NR1.

### Claim 3 (depends on 1)

A secondary amine with formula (R1R2NR3)2NH according to claim 1, wherein said secondary amine comprises (R1R2NR3)2NR1 in the range of 0.1% w to 20% w.

### Claim 4

The use of a secondary amine with formula (R1R2NR3)2NH, wherein
each of R1 and R2 are a methyl group;
R3 being —CH2CH2OCH2CH2—
as catalyst in the reaction of isocyanates and isocyanate reactive compounds for providing polyurethane.
