    摘要: 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.
