Nano-12-Tungstophosporic Acid Cesium Salt Synthesized by Ultrasound as Catalyst for Alkylation of Benzene with dec-1-ene

Abstract

Nano 12-tungtophosphoric acid cesium salt (Cs-TPA) was synthesized under ultrasonic irradiation in nanoscale. The obtained catalyst was characterized by various methods. These analyzes indicate that the chemical structure and crystallinity of nano Cs-TPA remained unchanged while its morphology was found to be different from traditional Cs-TPA which is in irregular shape, becoming spherical with an average particle size of about 50 nm. Nano Cs-TPA was examined in the alkylation of benzene with dec-1-ene, its catalytic activity was remarkably enhanced compared to its original state. The catalyst reusability experiment also showed that the activity of nano Cs-TPA does not decrease even after five reused cycles.
