Welcome to Huimeng Bio-tech

Huimeng is committed to becoming an intelligent agrochemical technology enterprise that continually creates value for customers.

Huimeng Bio-tech is a biotechnology enterprise integrated of research, development, production and sales of high-tech products, such as pesticide and pharmaceutical intermediates, biological fermentation chiral compounds, agrochemical technicals and formulations. We are headquartered in Heze, Shandong Province, with a total asset of 1.236 billion yuan, a total area of 360,000 square meters, and nearly 750 employees nationwide. We have three production bases in Shandong, Anhui and Heilongjiang, respectively, and two R&D centers in Suzhou and Shandong. Huimeng Bio-tech is the first factory in China to realize the large-scale production of DCTF (2, 3-dichloro-5-trifluoromethyl pyridine) which was awarded as "Single Champion Product" by the Ministry of Industry and Information Technology on December 21, 2020.

Since the establishment of Huimeng Bio-tech, we have been deeply engaged in R&D and large-scale production of chlorination and fluorination for pyridine derivatives. We have years of technical accumulation and experience in synthetic routes of products, such as DCTF and CTC. Our products mainly include CCMP, DCTF and other pyridine fluorinated derivatives intermediates. Other products include new pesticides with high efficiency, low toxicity and low residue. At present, we have realized the development of the whole industry chain from organic and inorganic raw materials to primary and advanced intermediates and then to pesticide A.I.s and formulations.More details click: www.huimengchem.cn

What are the chemical properties of tungsten (VI) chloride?

  Tungsten(VI) chloride   also known as tungsten hexachloride, is a chemical compound with the formula WCl6. As one of the key compounds in tungsten chemistry, this substance is recognized for its high reactivity and versatility in various applications. In this article, we will delve into the intricate details of tungsten(VI) chloride, including its chemical properties, synthesis, industrial uses, and safety precautions. This guide aims to provide an in-depth understanding of WCl6, making it a valuable resource for professionals and researchers in the field of inorganic chemistry. Chemical Properties of Tungsten(VI) Chloride Tungsten(VI) chloride is a dark blue, crystalline solid that exists in two polymorphic forms: monoclinic and orthorhombic. The compound is highly reactive, particularly with moisture, making it hygroscopic. When exposed to air, WCl6 readily hydrolyzes to form tungsten oxychloride (WOCl4) and hydrogen chloride (HCl). Its high reactivity is attributed to the...
