oxalic acid Oxalic acid is an organic substance with the chemical formula of C It is a metabolite of organisms. It is a binary weak acid, which is widely distributed in plants, animals and fungi and plays different functions in different organisms. It is found that more than 100 kinds of plants are rich in oxalic acid, especially spinach, amaranth, sugar beet, purslane, taro, sweet potato and rhubarb. Because oxalic acid can reduce the bioavailability of mineral elements, it is easy to form calcium oxalate with calcium ions in human body, resulting in kidney stones, oxalic acid is often considered as an antagonist for the absorption and utilization of mineral elements. Its anhydride is carbon trioxide.

Acetic Acid Acetic acid, also known as acetic acid and glacial acetic acid, with chemical formula of CH3COOH, is an organic monobasic acid, which is the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic solid with a freezing point of 16.6(62) and colorless crystals after solidification. Its aqueous solution is weakly acidic and highly corrosive, and steam can irritate eyes and nose. 1) Glacial acetic acid is one of the most important organic raw materials, mainly used in vinyl acetate, acetic anhydride, cellulose acetate etc; 2) Glacial acetic acid is an important raw material for synthetic fibers, adhesives and dyes, etc; 3) Glacial acetic acid is also an excellent organic solvent, widely used in plastics, rubber, printing and other industries.

Glacial acetic acid (CH3COOH) is commonly used as analytical reagents, general-purpose solvents, non-aqueous titration solvents, chromatographic analysis reagents, and organic synthesis. used for the synthesis of vinyl acetate, cellulose acetate, acetate, metal acetate and halo-acetic acid. It is also an important raw material for pharmaceuticals, dyes, pesticides and organic synthesis.

Hastelloy C-276 is a nickel-molybdenum-chromium superalloy with exceptional corrosion resistance in a variety of aggressive media. It was developed by Haynes International in the 1960s as a more versatile alternative to other nickel alloys such as Hastelloy B-2 and Hastelloy C-4. The high chromium content in Hastelloy C-276 provides superior resistance to oxidizing environments, while the molybdenum and tungsten enhance resistance to reducing media. The nickel content also makes Hastelloy C-276 highly resistant to chloride-induced stress corrosion cracking. Hastelloy C-276 has a wide range of applications in industries such as chemical processing, pulp and paper production, waste treatment, and pollution control. Its resistance to hot sulfuric acid and chlorine environments makes it suitable for use in scrubbers, ducting, and piping systems. It is also used in flue gas desulfurization systems and in the production of organic chemicals such as acetic acid and acetic anhydride. Hastelloy C-276 is a versatile alloy that can be easily fabricated using traditional techniques such as hot and cold forming, welding, and machining. It can also be heat treated to optimize its properties for specific applications. For example, annealing at temperatures between 2050�°F and 2150�°F can improve resistance to intergranular attack, while solution annealing at 2150�°F followed by rapid quenching can enhance resistance to localized corrosion. Overall, Hastelloy C-276 is an excellent choice for applications that require superior corrosion resistance and high strength in aggressive environments. Its versatility, ease of fabrication, and excellent mechanical properties make it a popular choice in a variety of industries. The following are the various national standards for Hastelloy C-276 alloy: United States: AMS 5750, AMS 5751, AMS 5796, AMS 5587, ASTM B366, ASTM B462, ASTM B574, ASTM B575, ASTM B619, ASTM B622, ASTM B626, UNS N10276 Europe: EN 2.4819 Germany: DIN 17744 France: AFNOR NC 17 D United Kingdom: BS HR 202, BS HR 403 Japan: JIS NW 0276 We can offer the following products:Hastelloy C-276 coil; Hastelloy C-276 strip;Hastelloy C-276 plate; Hastelloy C-276 sheets; Hastelloy C-276 tube; Hastelloy C-276 pipe;Hastelloy C-276 flat; Hastelloy C-276 bar GB:GH2761/JIS:NW 0276/UNS :N10276/W.Nr:2.4819 Hastelloy C-276 has a wide range of applications in industries such as: Chemical processing Pulp and paper production Waste treatment Pollution control Scrubbers, ducting, and piping systems in sulfuric acid and chlorine environments Flue gas desulfurization systems Production of organic chemicals such as acetic acid and acetic anhydride. It is also used in various other applications where corrosion resistance and high strength are critical.

What is acetic acid Acetic acid is also known as ethanoic acid, ethylic acid, vinegar acid, and methane carboxylic acid. Acetic acid is a byproduct of fermentation, and gives vinegar its characteristic odor. Vinegar is about 4-6% acetic acid in water. More concentrated solutions can be found in laboratory use, and pure acetic acid containing only traces of water is known as glacial acetic acid. Dilute solutions like vinegar can contact skin with no harm, but more concentrated solutions will burn the skin. Glacial acetic acid can cause skin burns and permanent eye damage, and will corrode metal. What is acetic acid used for? Acetic acid is used in the manufacture of acetic anhydride, cellulose acetate, vinyl acetate monomer, acetic esters, chloroacetic acid, plastics, dyes, insecticides, photographic chemicals, and rubber. Other commercial uses include the manufacture of vitamins, antibiotics, hormones, and organic chemicals, and as a food additive (acidulant). It is also used in various textile printing processes.
