Abstract�� This paper discussed the material of equipment which was used to prepare diethyl oxalate by CO coupling\|regeneration reaction with the method of weight.The seven kinds of metal material,such as 306,314L,316L,Zr,Ti(2),Ti(10),1Cr18Ni9Ti and one kind nonmetal material(PE)have been hung in the liquid compound in the regeneration reactor for 1500hours.The experiment indicative that the corrosion rate of the 306 is the biggest,in the after is 316L,Ti(10),1Cr18Ni9Ti,zincorium(Zr),Ti(2),that of PE is lest;1Cr18Ni9Ti is the better material of equipment.
