摘要
Mesoporous M(Al, Zr, Al-Zr)-SBA-15 catalysts prepared by a direct method were used for the hydroxyalkylation of phenol with formaldehyde to bisphenol F in the presence of water. The results showed that M(20)-SBA-15 with the Si/M molar ratio of 20 exhibited higher catalytic activity. The isomer distribution of bisphenol F could be regulated in the hydroxyalkylation of phenol with formaldehyde by changing the Al/Zr ratio in M(20)-SBA-15 catalysts. Al(20)-SBA-15 was in favor of the formation of 4,4'-isomer, whereas Zr(20)-SBA-15 was in favor of the formation of 2,4'- and 2,2'-isomers. (C) 2015 Elsevier B.V. All rights reserved.
