The CHIPS Act Begins Conference

CHIPS Act Begins Conference

Electronic Fluorocarbons applauds the announcement that Creating Helpful Incentives to Produce Semiconductors for America (CHIPS) Act has moved to conference. The Bill entered the conference period as part of The United States Innovation and Competition Act (USICA). The Bill has 109 conferees and hopes to see a final version early this summer.

Monitoring Supply Chain

Gas Supply Chain Remains In Tact Despite Global Unrest

Russia’s invasion of Ukraine has caused many far-reaching geopolitical repercussions. Our thoughts and prayers are with those that are impacted by the aggressive behavior. We are continuing to monitor international sanctions related to Russia’s aggression in the Ukraine and acknowledge the potential risk of impact to the gas supply chain. EFC has proactively positioned our global operations to react to this current situation and it’s effect on industry gas supply.

Our gas supply chain is intact. Since our inception, we have built our brand around cultivating strong global relationships with our suppliers. Pre-pandemic, this allowed us to maintain a competitive edge when providing you with pricing. During the height of COVID-19, these relationships enabled us to thrive during an international industry gas supply chain crisis. Now, in the wake of our current geopolitical climate, we have adapted our sourcing strategy to continue to provide you with product.

Krypton and Xenon Demand Results In Several Applications

Krypton and Xenon in Semiconductors

Krypton and xenon are produced from the air. Krypton is naturally present in the air at a concentration of 1 ppm and xenon is present at a concentration of 87 ppb. Both are collected as secondary products of cryogenic air separation at air separation units (ASUs). ASUs separate the components of air based on their boiling points using cryogenic distillation. This is the common method of production for oxygen, nitrogen, argon, as well as rare gases neon, krypton, and xenon. There are many ASUs around the globe. The ability to produce krypton and xenon is not inherently part of the process as it requires additional equipment beyond that required to collect oxygen or nitrogen. The krypton and xenon price when an ASU is planned and built determines if the capability to collect these gases is added.

Final Ruling on EPA Hydrofluorocarbons Phasedown in Effect

Understanding Allocations: EPA’s Ruling on the Phasedown of Hydrofluorocarbons (HFCs)

As of January 1, 2022, the EPA’s ruling on the hydrofluorocarbons or HFC phasedown went into effect. This ruling addresses the production and consumption of hydrofluorocarbons (HFCs) maximizing reclamation and minimizing releases from equipment while facilitating the transition to next-generation technologies through an allocation process. The American Manufacturing and Innovation Act (AIM) mandated 85% reduction by 2036 and now, as ruling period begins, companies are racing to comply with the regulation.

Joint Research Partnership - EFC and University of Nebraska Lincoln

Electronic Fluorocarbons Joint Research Partnership with the University of Nebraska-Lincoln (UNL)

Electronic Fluorocarbons has initiated a joint research program with researchers at the University of Nebraska-Lincoln (UNL). The work will focus on evaluation of low global warming (low-GWP) fluorocarbons as sustainable replacements for incumbent fluorocarbons (FCs) and hydrofluorocarbons (HFCs), which are used for critical semiconductor etching applications in the semiconductor materials processing area. The continued use of the incumbent fluorocarbon and hydrofluorocarbon gases in semiconductor etching applications is a subject of great importance. There are currently no viable alternatives to the continued use of these gases, although these “greenhouse gases” have a negative impact on the environment.

Rare Gases: Krypton and Xenon Applications

Xenon is a colorless, odorless, noble gas. Xenon is found in the atmosphere at 87 parts per billion. Like other rare gases, xenon is produced by using cryogenic distillation to extract it from the air. Electronic Fluorocarbons is a leading supplier of rare gases, including xenon, with established global supply chains to ensure reliable delivery.

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.
