Title:
【発明の名称】第三級アミノ炭酸エステルとアミノエーテルの製造方法
Document Type and Number:
Japanese Patent JPH11509527
Kind Code:
A
Abstract:
The invention relates to processes for producing di-(tertiary aminoalkyl) carbonate including the step of reacting a tertiary alkanolamine with methyl alkyl carbonate in the presence of a transesterification catalyst to form tertiary aminoalkyl alkyl carbonate, wherein some of the tertiary alkanolamine reacts with the tertiary aminoalkyl alkyl carbonate to form di-(tertiary aminoalkyl) carbonate. The invention also relates to processes for producing di-(tertiary aminoalkyl) carbonate including the steps of (i) reacting dimethyl carbonate with an alcohol in the presence of a transesterification catalyst to form a methyl alkyl carbonate, and (ii) reacting a tertiary alkanolamine with the methyl alkyl carbonate formed in step i) in the presence of a transesterification catalyst to form tertiary aminoalkyl alkyl carbonate, wherein some of the tertiary alkanolamine reacts with the tertiary aminoalkyl alkyl carbonate to form di-(tertiary aminoalkyl) carbonate.
