What is 4-tert-Butylphenol?

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 4-tert-Butylphenol which has developed particularly rapidly in recent years. Do you know about 4-tert-Butylphenol?


The official answer:P-test-butyl phenol (English name p-test-Butylphenol, 4-t-Butylphenol) is also known as 4-start-butyl phenol, 1-hydroxy-4-test-butylbenzene, 4-(1,1,dimethyl ethyl)phenol, or PTBP. 4-Hydroxy-4-test-butylbenzene, 4-(1,1-Dimethylethyl)phenol, abbreviated as PTBP. test-Butylphenol is a white or native white flaky solid at room temperature, with a special smell of alkyl phenol. When exposed to open flame, it can burn. Combustible but not flammable, heat decomposition and release of toxic gases. Soluble in alcohols, esters, alkanes, aromatic hydrocarbons, and other organic solvents, such as ethanol, acetone, butyl acetate, gasoline, toluene, etc. Slightly soluble in water, soluble in strong alkali solution. The product has the common characteristics of phenolic substances, and its color gradually deepens when exposed to light, heat, and air. This product is toxic and moderately irritating to the skin, mucous membrane, and eyes. It is toxic to aquatic organisms and may have long-term adverse effects on the water body environment. The main use is for the synthesis of p-tert-butyl phenolic resin. It can also be used as a polymerization inhibitor and stabilizer. The molecular formula is C10H14O.

What’s the application of 4-tert-Butylphenol?

(1)p-test-butyl-phenol has antioxidant properties and can be used as a stabilizer for rubber, soap, chlorinated hydrocarbons, and digestive fibers. UV absorber, anti-cracking agent for pesticide, rubber, and paint. For example, it is used as a stabilizer for polycarbonate resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene. In addition, it is the raw material for the manufacture of pharmaceutical insect repellents, pesticide acaricide Clothianidin, spices, plant protection agents. Also used as softeners, solvents, additives for dyes and paints, antioxidants for lubricants, emulsion breakers for oil fields, and additives for motor fuels.

(2)Used in oil-soluble phenolic resin, the product can be condensed with formaldehyde to obtain a variety of products. In the neoprene system adhesive mixed with the product 10-15%, to obtain soluble resin, such adhesives are mainly used in transportation, construction, civil engineering, shoemaking, etc. In printing ink, it can be used for rosin modification, offset printing, advanced photogravure, etc. In terms of insulation varnish, it can be applied to coil impregnation varnish and laminate varnish, etc.

(3) Used in polycarbonate production, as the reaction terminator of photos polycarbonate, the amount of Chemicalbook added is 1-3% of the resin.

 (4) Used in epoxy resin, xylene resin modification; as PVC stabilizer, surfactant, UV absorber.

 (5) It has antioxidant properties and can be used as a stabilizer of rubber, soap, chlorinated hydrocarbon, and nitrocellulose. It is also used as a raw material for insect repellent (medicine), acaricide, acaricide (pesticide) and plant protection agent, spice, synthetic resin, and as an additive for softener, solvent, dye, and paint. It can also be used as a component of emulsion breaker for oil fields and additive for motor oil.

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.
