Octafluoropropane can be used in semiconductor and medical fields. There are few mass production companies in my country.

Octafluoropropane, with the chemical formula C3F8, also known as perfluoropropane, is a perfluorinated compound that appears as a colorless gas. Octafluoropropane has stable chemical properties, is difficult to dissolve in water and organic matter, and is incombustible. However, there is a danger of explosion when exposed to high heat in a closed container. It can be mixed with flammable gases and burned, and the decomposition product is toxic hydrogen fluoride.

The preparation methods of octafluoropropane mainly include: using activated carbon and high-concentration fluorine gas as raw materials, reacting in a reaction furnace under certain temperature conditions, and the obtained reactants are subjected to dust removal, alkali washing, dehydration and other processes to obtain a crude product, which is then refined High-purity products are obtained through distillation, adsorption, dehydration and other processes; it is obtained through addition reaction using hexafluoropropylene as raw material; it is extracted from the by-products of the preparation of fluorocarbon gases such as carbon tetrafluoride (CF4).

According to the “2021-2025 Octafluoropropane Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center, semiconductor It is one of the important application areas of octafluoropropane. In the semiconductor industry, octafluoropropane can be used in plasma etching and device surface cleaning. In order to meet the requirements of etching accuracy and improve the yield rate of silicon wafers, octafluoropropane for semiconductors has high impurity content and purity requirements. Generally, the purity needs to be above 99.999% (5N). As semiconductor manufacturing processes continue to shrink, silicon wafer defect tolerance continues to decrease, so the purity requirements of octafluoropropane for semiconductors continue to increase.

Medical treatment is another important application field of octafluoropropane. Octafluoropropane can be used to prepare ultrasound contrast agents, which can be used in the field of ultrasound contrast to enhance the backscatter of ultrasound signals; it can be used as a blood cell tracer, which can reflect the blood perfusion of organs without interfering with hemodynamics; it can be used as Eyeball filler, effectively seals retinal tears, promotes retinal reattachment, and is used in the field of retinal detachment surgery. In addition, octafluoropropane can also be used in gas insulation, low-temperature refrigeration, polyurethane material foaming and other fields.

In overseas markets, the main manufacturers of octafluoropropane include Air Liquide of France, Linde Group of Germany, Merck Group of Germany, Praxair of the United States, and Taiyo of Japan. Taiyo Nippon Sanso, Kanto Denka Kogyo, Showa Denko, etc. In the Chinese market, the main manufacturers of octafluoropropane include China Shipbuilding Industry Corporation (Handan) Perry Special Gas Co., Ltd., Sichuan Fuhuaxin New Material Technology Co., Ltd., Guangdong Huate Gas Co., Ltd., etc.

Industry analysts said that electronic-grade high-purity octafluoropropane has high requirements for impurity content and purity of products. If problems arise, directly Affects the quality and yield of silicon wafers; the medical field has high safety requirements for octafluoropropane. For example, if there is a problem with octafluoropropane for ophthalmic use, it will cause blindness or low vision in patients. The technical barriers to octafluoropropane production are high, and the number of companies capable of mass production in my country is relatively small. These companies have greater room for development.
