Phosphoric acid CAS# 7664-38-2

Description of Phosphoric acid

  • Phosphoric acid (English: phosphoric acid) or orthophosphoric acid (orthophosphoric acid), chemical formula H3PO4, is a common inorganic acid, not volatile, not easy to decompose, almost no oxidation. With the generality of acid, it is a strong acid in ternary, its acidity is weaker than hydrochloric acid, sulfuric acid, nitric acid, but stronger than acetic acid, boric acid, etc.. It can be obtained by dissolving phosphorus pentoxide in hot water. Orthophosphoric acid is obtained by treating apatite with sulfuric acid in industry. Oxidation of phosphorus with nitric acid gives a purer phosphoric acid; usually a thick solution of 83%-98%, which, if concentrated again, gives colorless crystals. Phosphoric acid is easily deliquescent in air; heating will gradually lose water to get pyrophosphoric acid, and further water loss to get metaphosphoric acid. Phosphoric acid easily combines itself into various compounds such as pyrophosphoric acid or triphosphoric acid. Besides being used as a chemical reagent, phosphoric acid is also used mainly in pharmaceuticals, rust converters, food additives, solvents, electrolytes, fertilizers, metallurgy, feed, etc. It is also used in medical cosmetic and dental applications. Phosphoric acid is a ternary acid that dissociates three hydrogen ions, thus forming three different acid roots: dihydrogen phosphate H2PO- 4, hydrogen phosphate HPO2- 4 and phosphate PO3- 4.

What is Phosphoric acid?

  • With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Phosphoric acid which has developed particularly rapidly in recent years. Do you know about Phosphoric acid?
  • The official answer: Phosphoric acid, or orthophosphate, is a common inorganic acid, is a medium strong acid, the chemical formula is H3PO4, molecular weight is 97.994. It is not easy to volatilize, is not easy to decompose, and has almost no oxidation. It has the generality of acids, which is a ternary weak acid, and its acidity is weaker than hydrochloric acid, sulfuric acid, and nitric acid, but stronger than acetic acid, boric acid, etc. It can be obtained by dissolving phosphorus pentoxide in hot water. Orthophosphate is obtained by treating apatite with sulfuric acid in the industry. Phosphoric acid is deliquescized in air. Heating will lose water to get pyrophosphate, and then further water loss to get metaphosphoric acid. Phosphoric acid is used in pharmaceutical, food, fertilizer and other industries, including as a rust inhibitor, food additive, dental and orthopedics, EDIC corrosive agent, electrolyte, flux, dispersant, industrial corrosive agent, fertilizer raw material and components of home cleaning products. Also used as a chemical reagent, phosphate is a nutrient for all life forms.

 

What’s the application of Phosphoric acid?

  • Agriculture: Phosphoric acid is the raw material for the production of important phosphate fertilizers (calcium superphosphate, potassium dihydrogen phosphate, etc.) and is also the raw material for the production of feed nutrients (calcium dihydrogen phosphate).
  • Industrial: Phosphoric acid is an important chemical raw material, the main role is as follows:
  • 1. Treat the metal surface and form an insoluble phosphate film on the metal surface to protect the metal from corrosion.
  • 2. Mixed with nitric acid as a chemical polish to improve the finish of the metal surface.
  • 3, the production of washing products, insecticide raw materials phosphate esters.
  • 4. Raw materials for the production of phosphorus-containing flame retardants.
  • Food: Phosphoric acid is one of the food additives, as an acidulant, yeast nutrient in food, cola contains phosphoric acid. Phosphate is also an important food additive and can be used as a nutritional enhancer.
  • Medicine: Phosphoric acid can be used to prepare phosphorus-containing drugs, such as sodium glycerophosphate

WHY THEY SAY TO US

United Kingdom Giles
United Kingdom Giles
Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
