Process advances in production of ethanolamines

Some typical processes which appeared in recent years were reviewed on the basis of increasing the yield of monoethanol amine or diethanol amine and improving the quality of triethanol amine product.The tendency of developing the technology of producing ethanolamines in China is to adjust the product layout by means of modifying the process,developing new catalysts with high efficiency and converting among different ethanolamines,so as to improve the product quality and lower the energy consumption.
