cellulose bonded n-propyl diethylene tetra sulfamic acid (cbpdetsa) was successfully applied as a green and recyclable acidic catalyst for the synthesis of tetrahydrobenzo [a] xanthene-11-one as an important class of potentially bioactive compounds. the products are obtained by the coupling of 2-naphtol , cyclohexadione and aldehyde derivatives in good to high yields (70- 92%) under solvent-fre...

A simple and cost-effective method for the synthesis of sulfated β-cyclodextrin, one most widely used chiral mobile phase additives, using sulfamic acid as a sulfonating agent has been described. The was optimized, synthesized product characterized by spectroscopic, size-exclusion chromatographic, thermal, microscopic methods compared to marketed Sigma Aldrich β-cyclodextrin. β-Cyclodextrin, hy...

Abstract The deterioration of iron-based alloys, especially mild steel (MS) is one amongst the most challenging problems faced in various chemical industries. present work focuses on potential activity a naphthalimide derivative namely 2-(2-hydroxyethyl)benzo[de]isoquinoline-1,3-dione (HBIQ) as corrosion inhibitor for MS sulfamic acid (SA) medium temperature range from 303 to 323 K. Potentiodyn...
