Description of Terephthalaldehyde

Terephthalaldehyde is an important fine chemical material downstream of paraxylene. Because of two active aldehyde groups in its molecular structure, it can be self-polymerized or copolymerized with other monomers to form polymeric materials, which are mainly used in the synthesis of fluorescent materials, catalyst carriers, and other polymeric products. Terephthalaldehyde is traditionally produced by chlorination of paraxylene, followed by hydrolysis in the presence of nitric acid or metal oxides.

What is Terephthalaldehyde?

  • 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 Terephthalaldehyde which has developed particularly rapidly in recent years. Do you know about Terephthalaldehyde?
  • The official answer: Terephthalaldehyde is an important fine chemical material downstream of paraxylene. Because of two active aldehyde groups in its molecular structure, it can be self-polymerized or copolymerized with other monomers to form polymeric materials, which are mainly used in the synthesis of fluorescent materials, catalyst carriers, and other polymeric products. Terephthalaldehyde is traditionally produced by chlorination of paraxylene, followed by hydrolysis in the presence of nitric acid or metal oxides.

What’s the application of Terephthalaldehyde?

  • It is mainly used in the production of whitening agents, resins, plastics, pesticides, etc.; bromocyclopentane is mainly produced for the synthesis of a variety of organic substances; solid iodophor disinfectant is a new type of disinfectant made of surfactant as a carrier and complexed with iodine elements, with broad-spectrum, high efficiency, strong bactericidal power, strong and stable sex, safe to use, suitable for hospital pre-surgical skin disinfection, oral cavity, intestinal tract, urethra, cervical mucosa Disinfection of skin, oral cavity, intestine, urinary tract and cervical mucosa before surgery.

    • Preparation method:
  • Using p-xylene, carbon tetrachloride, azobisisobutyronitrile, and chlorine gas as raw materials and solvents, benzyl chloride was obtained, which was later oxidized under the catalytic action of nitric acid and zinc nitrate. The addition of zinc nitrate improved the yield of p-terephthalaldehyde to over 89% and the product purity was higher than 99.0%. Chlorinated hydrolysis usually directly uses highly toxic chlorine gas, which is very unfriendly to the environment. To avoid the direct use of chlorine gas, N-fluorosis(benzenesulfonamide) and sodium chloride were firstly used to react with p-xylene for the highly selective synthesis of p-dichlorobenzene, followed by 98% concentrated sulfuric acid and manganese dioxide catalysis to obtain the crude terephthalaldehyde, and finally, sodium hydroxide was used to neutralize the oxidation mother liquor, and the finished terephthalaldehyde was obtained by recrystallization in ethanol-water mixture with a 77% weight yield of terephthalaldehyde.

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.
