| Abstract: | Both buty1 acetate (n) and propy1 acetate (i) can be used as azeotrope agent in the equipment for purifying thin acetic acid.In this article,some aspects about those two processes,such as investment,operation,consumed cost,production capability and time for stabilization are compared.The plant using the buty1 acetate (n) as the azeotrope agent for reclaiming has the characteristics of lesser investment;lower consumed cost,easier access and the annual value of 1 400 000 yuan can be reached. |
