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.
The method of synthesizing (E)-1,2-di(pyridine-2-yl)ethene-1,2-diol involves dimerization of 2-pyridinecarboxaldehyde (also referred to herein as “picolinaldehyde”). The synthesis of the desired…
Novel hybrid xerogel materials were synthesized by a sol-gel procedure. n-octadecyltriethoxysilane was co-condensed with and without different cross-linkers using Q0…
The preparation of new [MeC(CH2PPh2)3CuCl] 1 and its derivatives was carried out directly by mixing of CuCl and MeC(CH2PPh2)3 ligand in dry THF, the neutral precursor 1 served to prepare [MeC(…
