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.

Inexpensive, stable, selective, and recyclable nanocatalysts, waste regeneration, utilization of safe available solvents are interest important factors in laboratory science industrial applications green chemistry. Therefore, herein, biochar nanoparticles (BNPs) were synthesized through chicken manure pyrolysis as a novel method for recycling. Then, order to improve their recyclability, the obtained BNPs magnetized using magnetic nickel nanoparticles. surface (BMNPs) was modified by (3-chloropropyl)trimethoxysilane (3-CPTMS) further neodymium Schiff-base complex immobilized on BMNPs, denoted Nd-Schiff-base@BMNPs. The supported used practical, biocompatible, commercial, reusable heterogeneous nanocatalyst. support this nanocatalyst formed from manure; therefore, it is cheap, economically viable, also compatible with principles Nd-Schiff-base@BMNPs acts selectively organic reactions can easily be recovered an external magnet reused, which This characterized wavelength-dispersive X-ray spectroscopy (WDX), scanning electron microscopy (SEM), energy-dispersive (EDS), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), inductively coupled plasma (ICP), N
