Description of 14-Benzoquinone

14-Benzoquinone, commonly known as para-quinone, is a chemical compound with the formula C6H4O2. In a pure state, it forms bright-yellow crystals with a characteristic irritating odor, resembling that of chlorine, bleach, and hot plastic. This six-membered ring compound is the oxidized derivative of 1,4-hydroquinone. The molecule is multifunctional: it exhibits properties of a ketone, forming an oxime; an oxidant, forming the dihydroxy derivative; and an alkene, undergoing addition reactions, especially those typical for α,β-unsaturated ketones. 14-Benzoquinone is sensitive toward both strong mineral acids and alkali, which cause condensation and decomposition of the compound.

What is 14-Benzoquinone?

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 14-Benzoquinone which has developed particularly rapidly in recent years. Do you know about 14-Benzoquinone?

 

The official answer: P-benzoquinone is an organic compound with the chemical formula C6H4O2.

What’s the application of 14-Benzoquinone?

Yellow crystals. Flammable. Melting point 116℃, relative density 1.318 (20/4℃), soluble in ethanol, ether, and alkali, slightly soluble in water. Can sublimate. Its vapor is volatile and partially decomposed. It has an irritating odor similar to chlorine. Intermediate of dyestuff and medicine. Manufacture of hydroquinone and rubber antioxidant, acrylonitrile and vinyl acetate polymerization initiator and oxidizer, etc. Used in the manufacture of hydroquinone, used as intermediates of dyestuff and medicine, rubber antioxidant, polymerization inhibitor, antioxidant, developer, etc. Used as oxidant, also used in organic synthesis for qualitative determination of parsley bases, pyridine, azomethine, tyrosine, and hydroquinone. It is used in the determination of amino acids in analysis. 99% and Chemicalbook 99.5% high purity grade is used for the photometric determination of amines. Used in Diels-Alder cycloaddition of dienophiles to form naphthoquinones and 1,4-phenanthrenedione Production method dissolves aniline in dilute sulfuric acid, oxidizes it with manganese dioxide, separates and purifies it by steam distillation, crystallizes, dehydrates, and dries it to obtain the finished product. In industrial production, this process is also an intermediate step in the production of hydroquinone. In some occasions, such as reagent production drug manufacturing, it is also used to prepare p-benzoquinone by oxidation with hydroquinone as raw material. Raw material consumption quota: aniline 2000kg/t, sulfuric acid (93%) 8500kg/t, soft manganese ore powder (containing 60-65% manganese) 9500kg/t.

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.
