Prof. Ismael Warad, Dr. Mohammed Suleiman Shtaya, Dr. Iyad ‎Saadeddin from the Chemistry Department of An-Najah University, and ‎Isra Aboasbah, an MA student in Chemistry at the University, have obtained a patent for their  invention by JUSTIA Patent in the U.S.‎


The patent titled: “Sulfonamide corrosion inhibitors “, included other ‎inventors: Dr. Nabil Al-Zeqri from Yemen, Dr. Ali Alsalme from Saudi ‎Arabia, and Prof. Abdelkader Zarrouk from Morocco along with the ‎Palestinian researchers from An-Najah University. ‎

The sulfonamide corrosion inhibitors are compounds of formula A or ‎formula B, as follows: A method of synthesizing the sulfonamide ‎corrosion inhibitors includes functionalizing a polyamine precursor with a ‎sulfonyl chloride derivative by dehydrochlorination. The polyamine ‎precursor may be bis(3-aminopropyl) amine and the sulfonyl chloride ‎derivative may be methanesulfonyl chloride. The sulfonamide corrosion ‎inhibitors may be applied alone or in any combination as corrosion ‎inhibitors of a metal and are shown to be effective inhibitors of corrosion ‎of iron or iron alloys in acidic conditions.‎
