甲基叔戊基醚裂解催化剂的研究

STUDY ON METHYL t-AMYL ETHER CRACKING CATALYSTS

采用自制的固体酸催化剂 ( HF/Al2 O3)对甲基叔戊基醚 ( MTAE)裂解制异戊烯的反应进行了考察 :实验表明 ,该催化剂具有较高的催化活性 ;在反应温度为 2 1 0℃ ,反应压力为 0 .1 MPa,液时空速为 1 .9h- 1时 ,MTAE的裂解率达 99.0 % ,异戊烯的选择性为 99.0 %

Tertiary amylenes were prepared from methyl tamyl ether by cracking with a selfmade HF/Al 2O 3 catalyst. Under the conditions of reaction temperature 210 ℃, pressure 0.1 MPa and L.H.S.V. 1.9 h -1 , value of conversion reaches 99.0%, with a selectivity of 99.0%.
