Beijing Yuji Science & Technology Co., Ltd. has successfully developed mass production technology of hexafluoro-1,3-butadiene (C4F6) through independent R&D and innovation to meet the increasing demand of the semiconductor industry for green and efficient dry etching gases. Earlier, the key technologies for C4F6 production and purification had been monopolized by chemical giants in developed countries, resulting in relatively small amount production of C4F6 and higher market prices. Both C4F6 sold and used in the domestic market were imported. With the support of policies and the rapid development of Very Large Scale Integration Circuit (VLSI), the market demand for C4F6 has increased significantly and its localization is imminent.
Relying on a strong fluorine chemical research and development technical team, we have explored an easily industrialized hexafluoro-1,3-butadiene (C4F6) synthesis method and applied for a patent with independent intellectual property rights. We successful realized local production of C4F6. This method uses a simple reaction system and suitable reaction conditions to synthesize hexafluoro-1,3-butadiene with high yields. The raw materials are cheap, the source is convenient to get, and the product separation and purification are simple; the synthetic process is safe and suitable for industrial production. Beijing Yuji Tech has fully launched the commercial production of C4F6 (hexafluoro-1-butadiene) through its own factory in the second half of 2016.
C4F6, also known as hexafluoro-1,3-butadiene, HFBD, has a high industrial value, and has become one of the alternatives to traditional fluorine-containing electronic gas by excellent comprehensive performance. C4F6 is a widely used industrial raw material, its downstream products can be used for precise electronic circuit board cleaning agents, pesticides and insecticides and has a high application value in the synthesis of fluorine-containing pharmaceutical intermediates or other fluorine-containing fine chemicals. In the synthesis of fluorine-containing polymers, it can be used as a monomer to synthesize polyhexafluorobutadiene, it can also be used with other monomers to synthesize fluorine rubber or resin with excellent electrical properties.
