摘要
PURPOSE: A carbon dioxide absorbent including trialkoxyhydroxyphosphonium carboxylate - based ionic liquid and a separation method of carbon dioxide from a gas mixture are provided to reduce manufacturing costs, and to improve carbon dioxide absorption. CONSTITUTION: A carbon dioxide absorbent includes trialkoxyhydroxyphosphonium carboxylate - based ionic liquid marked as a chemical formula 1. In the chemical formula 1, R1 is an alkyl group or an aryl group of a carbon number 1 ~ 8. R2 is an alkyl group of carbon number 1 ~ 6, a halo alkyl group or an aryl group of carbon number 1 ~ 6. The trialkoxyhydroxyphosphonium carboxylate - based ionic liquid is manufactured by reacting trialkyl phosphate with organic acid.
