Polyethyleneimine-supported cobalt (II) chloride as a novel polymeric nanocomposite acidic catalyst for the one-stage transesterification reaction of ethyl acetate with various alcohols is reported. The was characterized by Fourier transform infrared spectroscopy, X-ray powder diffraction, transmission electron microscopy, scanning dynamic light scattering technique, and thermal gravimetric analysis. Furthermore, inductively coupled plasma atomic absorption spectroscopy were used to determine quantity Cobalt nanoparticles in catalyst. By adding (0.10 g, 0.20 mol%) n-hexane/chloroform (5.0 cm3) solvent under reflux conditions, studies demonstrated successful reactions excellent yields (80–98%) short times (0.50–1.30 h) using substrates on scale 1.0 mmol. Seven consecutive could be performed without significantly decreasing its activity. most noteworthy aspects this process are low cost, safety, environmental friendliness due catalyst's non-toxicity, straightforward operation, effective outcomes.
