Offretite Zeolite Single Crystals Synthesized by Amphiphile-Templating Approach

Offretite zeolite synthesis in the presence of cetyltrimethylammonium bromide (CTABr) is reported. The offretite crystals were synthesized with a high crystallinity and hexagonal prismatic shape after only 72 h hydrothermal treatment at 180 °C. CTABr has dual-functions during crystallization offretite, viz. as structure-directing agent mesoporogen. resulting crystals, Si/Al ratio 4.1, possess more acid sites than conventional due to their hierarchical structure. also reactive its counterpart acylation 2-methylfuran for biofuel production under non-microwave instant heating condition, giving 83.5% conversion 100% selectivity desired product 2-acetyl-5-methylfuran. Hence, this amphiphile approach offers another cost-effective alternative route crystallizing materials that require expensive organic templates.
