Abstract:  A simple and efficient procedure for the preparation of boron nitride bound N-propyl triethylenetetramine sulfonic acid (BN-BPTETSA) by the reaction of boron nitride bound N-propyl triethylenetetramine (3-TETANP BN) with chlorosulfonic acid in chloroform is described. The boron nitride (BN) nanomaterial was prepared by first activating BN with nitric acid under reflux for 24h. Thereafter trimethoxy -3-mercaptopropylchloride was added, refluxed for 24 h then an excess of triethylenetetramine was added in anhydrous xylene and the system was refluxed. After filtration and washing of the filter cake with xylene, chlorosulfonic acid was added drop-wise at 0 °C over a period of 3 h. Further filtration yielded a solid cake which was washed with ethanol and air died. The morphological properties of catalyst was characterized by FT-IR, XRD, TEM, SEM, BET and Raman spectroscopy techniques. The preparation of the catalyst is safe and demonstrates high catalytic activity for the synthesis of piperazinyl quinolinyl carbaldehyde derivatives. Furthermore, a small amount of catalyst was used, demonstrated good reusability and may have potential for industrial applications in the future. Copyright © 2018 VBRI Press.
