What is Tributyl phosphate?

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 Tributyl phosphate which has developed particularly rapidly in recent years. Do you know about Tributyl phosphate?

 

The official answer: Tributyl phosphate is an organic compound with the chemical formula C12H27O4P/(C4H9)3PO4, which is a colorless, irritating odor liquid. Mainly used as a solvent, it is also often used as a plasticizer for nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, extractant for rare metals, etc., heat exchange medium. Because of its low surface tension and insoluble in water, it can be used as an industrial defoamer, effectively defoaming the film of formed foam in an unstable state and defoaming rapidly. It cannot be used in food/cosmetics.

What’s the application of Tributyl phosphate?

Uses: Used as gas chromatography stationary solution, the solvent of nitrocellulose and ethyl cellulose, plasticizer, rare earth metal separation agent, and organic synthesis intermediate

Use two: It has a better inhibiting effect on acrylates, methacrylates, acrylic acid, acrylonitrile, styrene, and butadiene, and its inhibiting performance is better than phenols.

Use III: Used as extractant of metal complexes, plasticizer of cellulose nitrate, cellulose acetate, chlorinated rubber and polyvinyl chloride, the solvent of paints, inks, and adhesives

Use IV: Used as the main plasticizer of cellulose nitrate, cellulose acetate, chlorinated rubber, and polyvinyl chloride, also commonly used as the solvent of paint, adhesive, and ink, defoamer, anti-static agent, extractant of rare earth elements. The LD50 for rats is 3000mg/kg.

Use V: Solvent for nitrocellulose and cellulose acetate, defoamer, heat exchange medium, plasticizer, extractant. Gas chromatography stationary solution (maximum use temperature 120 ℃, the solvent is ether) extraction of cobalt, iridium, manganese, molybdenum, palladium, rhodium, nickel, uranium, and tungsten, colorimetric determination of molybdenum. Organic synthesis.

WHY THEY SAY TO US

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.
