Method of obtaining a secondary amine or tertiary amine

摘要

The formula ^{(R 1} R ² NR ₃₎² NR ^4, respectively (wherein, the ^{R 2} and ^{R 1,} is selected from the group consisting of a methyl group, ethyl group, isopropyl group, from n- propyl and; ^{R 3} is, -CH _{2 CH 2} OCH ₂ CH _{2 -,} - CH ₂ CH ₂ OCH ₂ CH ₂ CH _{2 -,} and _{-CH 2 CH} 2 _CH 2 _OCH 2 _CH 2 _CH 2 - in the alkoxyalkyl group is selected from the group consisting of Yes; R ⁴ are tertiary amines or secondary amines with hydrogen, a methyl group, an ethyl group, an isopropyl group, n- propyl group, and a) is selected from the group consisting of groups having the formula R ¹ R ² NR ³ method of obtaining is provided. Is reacted with ammonia ^(OH) (α) R ¹ R ² NR 3, This step obtain a mixture comprising ^{(R 1} R ² NR ₃₎² NR ⁴ method; and the (β) the mixture I include; separating the ^(R 1 ^R 2 ^NR₃₎ 2 ^{NR 4.} None [Selection Figure]
