Researchers from An-Najah University Obtain U.S Patent
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.
