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 Boron trifluoride etherate which has developed particularly rapidly in recent years. Do you know about Boron trifluoride etherate?


The official answer: Boron trifluoride ether is an organic substance, molecular formula BF3-C2H5OC2H5, colorless or dark brown liquid, toxic, can be used as a catalyst for acetylation, alkylation, polymerization, dehydration and condensation reaction, also used as analytical reagent and epoxy resin curing agent, it is also the basic raw material for the manufacture of borohydride high energy fuel and extraction of isotope boron 10.

What’s the application of Boron trifluoride etherate?

Boron trifluoride ethyl ether complex, commonly known as boron trifluoride diethyl ether, is commonly used as a catalyst for cationic polymerization, as well as a catalyst for the manufacture of paraben rubber and paraformaldehyde, and Chemicalbook is a basic raw material for the manufacture of borohydride high energy fuel and the extraction of isotopic boron. It is often used as a catalyst for chemical synthesis and is also the basic raw material for the manufacture of borohydride high-energy dyes and the extraction of isotope boron10. It is used as a catalyst for the synthesis of rubber, resin, and paint. It is used as a catalyst for hydrocarbonization and condensation reactions in organic synthesis (such as cis-butyl rubber, paraformaldehyde, gumarone, synthetic resins, etc.), as well as a basic raw material for the manufacture of borohydride high energy fuel or extraction of isotopic boron, and as a curing agent for epoxy resin, etc. It is used as a catalyst for acetylation, alkylation, polymerization, dehydration by the condensation reaction of organic synthesis and analytical reagent. It is the basic raw material for the manufacture of borohydride high-energy fuel and extraction of isotopic boron and is also used as a curing agent for epoxy resin. Used as a catalyst for organic synthesis (acetylation, alkylation, polymerization, dehydration, and condensation reaction) and analytical reagent.

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.
