Taiyo Fine Chemicals

For many years. we have been development and manufacturing organohalogen compounds which is synthesized with Phosphoryl Chloride, Phosphorus Pentachloride, Bromine, NBS, and Fluorine compounds. In 2017, we have introduced the HASTELLOY manufacturing kettle. Hastelloy is made of nickel-chromium-molybdenum alloy. It is a material resistant to corrosive gases such as hydrogen chloride, hydrogen bromide, hydrogen fluoride, etc. generated from the reaction, and strong alkalinity. We are working to meet a wide variety of needs by introducing our know-how and the updated equipment..


What is an organic halogen compound?

Fluorine, chlorine, bromine, and iodine, which are elements of Group 17 in the second column from the right of the Periodic Table, are called halogens. Organohalogen compounds are materials that contain these elements in their organic molecules and are essential to daily life. Halogen-substituted compounds can provide the modification the physical properties of organic compounds significantly due to their electron-withdrawing properties. Water repellency and flame retardancy can be provided for electronic material applications. These are used as intermediates for various kind of synthesis. In pharmaceutical and agrochemical applications, these have a characteristic effect on the biological activity in the final compound.


About fluorine compound

(Fuchigami.Toshio: Professor Emeritus, Tokyo Institute of Technology, Taiyo Fine Chemical Technical Advisor)

Fluorine compounds have chemical resistance, heat resistance, light resistance, non-adhesiveness, water repellency, oil repellency, low friction, electrical insulation, radiation sensitivity, low refractive index and dielectric constant, and unique bioactivity. The property of fluorine compounds are very unique and hard to be replaced by other general compound. Fluorine-based materials include ultra-weather-resistant paint that does not need to be repainted for more than 30 years, and fluorine-based films for agricultural houses that do not need to be replaced for more than 10 years, fibers, leather, and water-repellent and oil-repellent finishing agents for smartphones. .. Fluorine also contributes to energy and resource saving in the living environment and automobiles. Fluorine also supports the semiconductor and IT industries, and fluorine-based materials are also playing an important role in the development of clean energy such as lithium secondary batteries and fuel cells. On the other hand, turning to the physiologically active substances, the world’s best-selling drug for treating hyperlipidemia also contains fluorine, and a therapeutic drug for fluorine-containing glaucoma has been launched on the market in recent years. Furthermore, not only medicines, but also agricultural chemicals are becoming mainstream. Thus, fluorine is a very interesting element not only academically, but also industrially, medically and pharmacologically, and fluorine compounds are key materials that enrich our daily lives.
