Four new compounds from perylene dianhydride were prepared and tested for their anti-corrosion properties. Dizinc salt of perylene-3,4,9,10-tetracarboxylic acid dimagnesium salts acid, 5,5′-(1,3,8,10-tetraoxo-1,3,8,10-tetrahydroanthra[2,1,9-def:6,5,10-d′e′f′] diisoquinoline-2,9-diyl) bis(2-hydroxybenzoic acid) N,N′-bis[3,3′-(dimethylamino)propylamine]-3,4,9,10-perylenediimide characterized by a...

On a global scale, methanol is one of the most important feedstocks and used widely as solvent co-solvent. However, due to polar nature associated ability conduct current, small molecule can take part in galvanic corrosion metal storage tanks degrade barrier properties protective coatings. In present work, we investigated degradation two novolac epoxy coatings polyurethane (PU) coating exposed ...

Basalt rockwool wastes with large output, which are toxic and require expensive environmental treatment, produced during the production of rock wool. Hence, it is urgent to find an effective method reuse these materials. In this study, polyaniline (PANI)-coated basalt (BRWs) were prepared as fillers serve in coatings for anticorrosion study. Results show that PANI-coated BRW (PANI@BRW) had enha...
