Synthesis of Isopropylnaphthalene with SO_4~(2-)4TiO_2 Solid Superacid as Catalyst
QIANG Min etc.(Wuhan University of Science and Technology; Wuhan Hubei; 430081; China)
Abstract:SO 2- 4-TiO 2 solid superacid was used as catalyst in the alkylation of naphthalene with propylene to yield isopropylnaphthalene. The process is simple, lacking pollution and erosion. The optimal conditions of SO 2- 4-TiO 2 solid superacid are dipping acid concentration at 0.50?mol/L and calcinations temperature at 500?℃. The solid superacid can be used as catalyst two times in the alkylation of naphthalene, and the total composition of MIPN,DIPN, and TIPN in product is over 98%. When the consumpt...
