摘　　要：以脱除杂质后催化裂化汽油中C5馏分为原料，S-54型大孔磺酸正离子交换树脂为催化剂，将C5馏分与甲醇进行醚化反应制备了甲基叔戊基醚。结果表明，在压力为1．2MPa，甲醇／叔戊烯（摩尔比）为1．0～1．2，空速为3．0h^-1，反应温度为70．0～80．0℃的条件下，叔戊烯转化率约为60％。Tertiary amyl methyl ether （ TAME ） was prepared by etherification with pure C5 distillation in FCC gasoline and methanol as materials, large pore cationic exchange resin S -54 as catalyst. The results showed that under the condition of pressure 1.2 MPa, molar ratio of methanol to tertiary amylene 1.0 - 1.2, space velocity 3.0 h ^-1, temperature 70.0 - 80.0 ℃, the conversion of tertiary amylene could reach up to 60%.
