Sodium benzoate is the sodium salt of benzoic acid.It is an aromatic compound denoted by the chemical formula C7H5NaO2 with a molecular weight of 144.11. Mixed inhibitors act on both anodic and cathodic sites and they reduce the corrosion rate without a significant change in the corrosion potential, generally by surface adsorption over the surface of the steel in contact with the inhibitor and consequently forming a thin protective layer. Food Additive Status List. 532-32-1 - WXMKPNITSTVMEF-UHFFFAOYSA-M - Sodium benzoate [USAN:JAN:NF] - Similar structures search, synonyms, formulas, resource links, and other chemical information. The molecular structure is based on structures generated from information available in ECHA’s databases. The use and characterization of benzoates such as sodium benzoate, benzoic acid, calcium benzoate, zinc basic benzoate, aluminium basic benzoate and ferric benzoate as corrosion inhibitors and anticorrosive pigments for protective paints is well documented (Blustein and Zinola, 2004; Blustein et al., 2006, 2007a,b). Additionally, the sodium benzoate incorporated to a silicone coating was found to exhibit enhanced antibacterial performance in freshwater (Haque et al., 2005; Al-Juhni and Newby, 2006). In publications only general information can be found.37.

By using The Spruce, you accept our, Product Brands Containing Sodium Benzoate. Vol. As the carboxylic acid, the two oxygen atoms are nonequivalent.
In general, the inhibiting efficiencies appeared higher in the FAA and FAB than in the OPC system, where steel is exposed to a higher chloride concentration. Different inhibitors are used for different metals. View information & documentation regarding Sodium benzoate, including CAS, MSDS & more. (1975), Chet et al. However, the modes of action of both paints are different. For this reason, a study was carried out on the effects of, The corrosion behaviour of reinforced steel embedded in alkali-activated mortar, Handbook of Alkali-Activated Cements, Mortars and Concretes. Prismatic mortar specimens, with dimensions of 8 × 5.5 × 2 cm were prepared. Environmental Working Group. The successful employment of soluble compounds (benzoic acid, sodium benzoate, etc.) Sodium benzoate is not a molecule. However, nitrites are considered to be toxic substances (Hellawell, 1988), and there is growing interest to develop environmentally friendly substances that can act as corrosion inhibitors.
Structure, properties, spectra, suppliers and links for: Sodium Benzoate, 532-32-1. Vol. Phosphates, silicates and polyphosphates are also used. (1975) and Chet and Mitchell (1976) reported the use of non-toxic organic repellents, such as benzoic acid, tannic acid and acrylamide to inhibit the marine microbial film formation. The incorporation of ferric benzoate into the soluble matrix paint represented an advantage because it allowed a controlled pigment release with satisfactory antifouling action during six months exposure.

The selection and use of corrosion inhibitors is an important field of applied corrosion research and details on the formulation of inhibitor systems are private. Inhibition efficiency (IE) (%) values for carbonated OPC, FAA and FAB mortars in partial immersion in 1% chloride solution, inhibited with Mix A or Mix B. where Rpinh and Rpblank are the polarization resistance values estimated from the Nyquist plots in the presence and absence of the inhibitors, respectively. Molecular structure of tetrakis[μ-terephthalato-bis(cyclopentadienyl)titanium] showing the figure-of-eight folding of the 36-membered ring (reproduced by permission of Elsevier from J. Organomet. Organic polymer compounds such as amine and aminoalcohol (AMA) are also used. 30, Pg. She has contributed over 200 articles to The Spruce.

EC (Environment Canada). Uninhibited carbonated chloride-polluted FAA and FAB mortars exhibited higher Rp values (1–3 × 105 Ω cm2), indicating lower corrosion rates.
Finally, tests have been performed in a synthetic solution to verify whether the simultaneous use of GPH and 2AMB is compatible and whether their addition can efficiently hinder the corrosion attack in the presence of both chlorides and carbonation (Monticelli et al., 2011). It is a crystalline, odorless powder that dissolves in … Shopper’s Guide to Pesticides in Produce™, Environmental Working Group is a 501(c)(3) nonprofit corporation, EIN 52-2148600.
These results were similar to those expected for another type of paint like ‘fouling-release coatings’ (Brady, 2000; Hare, 2000). All Rights Reserved. Allergies and immunotoxicity: Ingredients linked to harm to the immune system, a class of health problems that manifest as allergic reactions or an impaired capacity to fight disease and repair damaged tissue in the body. Sodium benzoate is the sodium salt of benzoic acid, which is often used as a preservative and anti-corrosive agent in a variety of industries. Docusate sodium/sodium benzoate 121183-10-6 Chemsrc provides Sodium Benzoate(CAS#:532-32-1) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. Explain why benzoic acid with an 18O isotopic label in the hydroxyl oxygen atom can be prepared, but that it cannot be used in mechanistic studies in aqueous solutions. Substance Type: Chemical Substance. properties-White flakes/powder, -Ionic bond between the sodium ion and oxygen ion makes the coupound more soluable in water than Benzoic Acid 1313, 1935. Harvell, J, M. Bason and H. Maibach. Chem., 1987, 326, C37). The adsorption of the inhibitor on the metal surface follows similar rules as were discussed for deposition additives in Chapter 9. The electrical equivalent circuit (EEC) used to fit the impedance data of reinforced carbonated mortar specimens and subsequent partial immersion conditions in a distilled water solution polluted with 1% chlorides contains: Re is the electrolyte resistance, the RHF–CPEHF couple predominating at high frequencies may be associated to the dielectric properties of the mortar cover, the Rprod–CPEprod couple characterizes the layer of corrosion products on the steel surface, and the RCT–CPELF combination controlling the low frequency portion of the diagrams (and also containing a Warburg impedance element (W), in the case of OPC mortar immersed in Mix A or Mix B) is related to the electrochemical properties of the corroding carbon steel rebar.
