    Abstract: A pigment grade corrosion inhibitor and a method of forming the inhibitor is disclosed. The inhibitor is comprised of a host species comprised of an inorganic compound having a layered structure and a guest species comprised an anionic species of a weak acid. The host species is preferably a double hydroxide having a structure of: [M(II)1-xM(III)x(OH−)2] [An−x/n.y H2O], where M(II) is a divalent metal cationic species, M(III) is a trivalent metal cationic species, and An− is an anionic species, preferably with the species present in a range of: 0.2≦M(III)/(M(II)+M(III))≦0.4. The guest species include: ortho-phosphoric, pyrophosphoric, tripoly-phosphoric, polyphosphoric acid; mono- and di-alkyl or aryl-esters of ortho-phosphoric and pyrophosphoric acid; metaphosphoric, trimeta-phosphoric, poly-metaphosphoric acid; phosphorous (phosphonic) acid; derivatives of phosphonic acid; alkyl and aryl esters of thio-phosphoric and dithio-phosphoric acid; molybdic, phospho-molybdic, silico-molybdic acid; boric acid; cyanamidic acid; nitrous acid; derivatives of thio- and dithiocarbonic acid, including o-alkyl esters; derivatives of dithiocarbamic acid, including N-alkyl dithiocarbamates; pyrrolidinecarbodithioic acid; thio-organic compounds functionalized with at least one —SH group of acidic character, including: 2,5-dimercapto-1,3,4-thiadiazole (DMTD), 2,4-dimercapto-s-triazolo-[4,3-b]-1,3-4 thiadiazole, trithiocyanuric acid (TMT), and dithiocyanuric acid, various N—,S— and N,N—, S,S— and N,S-substituted derivatives of the above DMTD and TMT compounds; various S-substituted derivatives of trithiocyanuric acid; dimer and polymer derivatives of the above DMTD and TMT compounds, including 5,5′ dithio-bis (1,3,4 thiadiazole-2(3H)-thione or (DMTD)2, and (DMTD)n, polymers of DMTD and (TMT)2, dimers and polymers of TMT; various combinations of all the above; soluble salts of DMTD and TMT; poly-ammonium salt of DMTD or (DMTD)n and TMT formed with polyamines; mercapto-benzothiazole, mercapto-benzoxazole, mercapto-benzimidazole, and combinations, thereof; di- and poly-mercapto compounds, including: di-mercapto derivatives of thiophene, pyrrole, furane, diazoles, and thiadiazoles; di- and tri-mercapto derivatives of pyridine, diazines, triazines, benzimidazole, and benzothiazole, including dimercaptopyridine, 2, 4-dithiohydantoine, and 2,4,-dimercapto-6-amino-5-triazine; and carboxylic and di-carboxylic acids, including ascorbic, salicylic acid, phthalic acid, nitro-phthalic acid, succinic acid, and derivatives of succinic acid, including 1-(benzothiazol-2-ylthio)succinic acid.

    Abstract: A pigment grade corrosion inhibitor and a method of applying the inhibitor is disclosed. The inhibitor is comprised of a host species comprised of an inorganic compound having a layered structure and a guest species comprised an anionic species of a weak acid. The host species is preferably a double hydroxide having a structure of: [M(II)1−x M(III)x (OH−)2] [An−x/n.y H2O], where M(II) is a divalent metal cationic species, M(III) is a trivalent metal cationic species, and An− is an anionic species, preferably with the species present in a range of: 0.2≦M(III)/(M(II)+M(III))≦0.4. The guest species include: various phosphoric acids and derivatives thereof; boric acid; cyanamidic acid; nitrous acid; derivatives of thio- and dithiocarbonic acid; thio-organic compounds functionalized with at least one —SH group of acidic character, including: 2,5-dimercapto-1,3,4-thiadiazole (DMTD), 2,4-dimercapto-s-triazolo-[4,3-b]-1,3-4 thiadiazole, trithiocyanuric acid (TMT), and dithiocyanuric acid.
