The synthesis of asymmetric amine ethers proceeds via efficient transesterification. Two tertiary amine alcohol hydrogen sulfates are prepared in high yields and applied as intermediates of transesterification to synthesize asymmetric amine ethers, which has significant advantages over the conventional process.

A process is set forth for the selective removal of acid gases such as H2S, COS and CO2from a gas stream by contacting the stream with a bis tertiary amino alkyl solvent compound such as bis-(2-morpholino ethyl) ether. When used in an aqueous solution, the compounds catalytically hydrolyze COS to H2S and CO2.
本发明提出了一种选择性去除气流中 H2S、COS 和 CO2 等酸性气体的工艺,方法是将气流与双叔氨基烷基溶剂化合物(如双(2-吗啉基乙基)醚)接触。在水溶液中使用时,这些化合物可催化 COS 水解为 和 。
