چکیده
|
The dehydration of fructose to 5-hydroxymethylfurfural (hmf) was investigated in the presence of the brönsted-lewis acidic ionic liquids (ils). it was found that il (3-sulfonic acid)-propyl-triethylammonium chlorochrominate [ho3s-(ch2)3-net3]cl-crcl2 (molar fraction of crcl2 x = 0.55) had a good catalytic performance with 93.4% yield of hmf. il acid site played a more significant role than its brönsted counterpart in the reaction,and a synergetic effect of brönsted and lewis acid sites enhanced il catalytic performance. the reusability of il was good which could be reused up to 5 times without apparent decrease in the yield of hmf. © 2015,chemical society of pakistan. all rights reserved.
