- Abstract
Catalytic performance of benzenesulfonic acid was investigated for alkylation of thiophenic sulfur compounds with diene. The alkylates were confirmed by gas chromatography-mass spectrometry technique. The reaction conditions were optimized as follows: temperature is 85 °C, catalyst/feed weight ratio is 10 % and time is 80 min. Under the conditions, the conversion of thiophene was nearly 73 %. The catalyst exhibited some recycle-use performance. The catalytic activity could be maintained by addition of the fresh catalyst periodically and quantitatively.
