Industrial Synthetic Routes to C4F6, Hexafluoro-1,3-butadiene

A preferred route to C4F6 involves the readily available raw materials ICl and CTFE in a 3-step synthetic process as illustrated below in Scheme 1.  The basis of this chemistry has been known for nearly 70 years and was described in the past scientific literature by several workers including Hazeldine (J. Chem. Soc (1952) 4423), Hauptschein (JACS (1961) 83, 2495), and Ameduri (J. Fluorine Chem. (1995) 74, 261).  Moreover, similar process chemistry is described in the Russian Patents, RU 2246477 and RU 2272017.

Step 1 involves the 1,2 additions of the interhalogen ICl to CTFE and results in formation of the major and a minor 1,2-addition products. In step 2, reductive coupling with zinc of the 1,2-addition products provides the perhalogenated butane, HFTCB.  In the third process step, HFTCB is reductively dechlorinated with zinc in a polar solvent to provide high purity C4F6.  Purification of the final product often is facile owing to the large differences in volatility and polarity of C4F6 compared to the major contaminants such as organic solvent.

How ERP software changed our business

From the moment we receive your order at Electronic Fluorocarbons, several teams roar into action: purchasing, production planning, manufacturing and materials management, tracking, quality insurance, and accounting, to name a few. At your own company, you probably have as many—or more—teams and processes to serve your customers. We’ve found that our Enterprise Resource Planning (ERP) system makes us more efficient, ensures higher quality, and improves our data gathering, to help us meet ever-changing customer needs. Like most companies, we have found three main benefits from ERP: reduced process times, increased collaboration, and centralized enterprise-wide data.

EFC's 2018: Year End Review | News

Happy 2019! We hope you had an enjoyable and relaxing holiday season. We want to take a moment to reflect on the past year as well as share what we have in store for this coming year!

Hatfield Facility Expansion

In January 2017, we began operating out of our newly built 34,000 square-foot facility in Hatfield, PA. This year, we will complete construction on a 32,000 sqaure-foot fabrication, design, and R&D laboratory building. The expansion will allow us to grow our product line, improve efficiency, and hire additional staff. Dr. Robert Syvret will oversee the R&D laboratory which will let us to innovate and create pilot tests for new specialty gases. Read the press release to learn more about our expansion.

Specialty Gas Industry & Gas Tariffs in the US

Tariffs are a fee placed on imports to increase their price. All countries use tariffs to one extent or another. Importers and exporters of specialty gases are constantly shifting as new production facilities, new tariffs, and new demands emerge globally. The hope is that new sources for specialty gases will constantly arise to fill the gap when old sources aren’t available.
