Seven fluoroisobutyronitrile (C4F7N) has excellent insulation properties and low greenhouse effect, and is a highly regarded SF6 substitute gas. However, heptafluoroisobutyronitrile has not yet been industrially produced, and its preparation technology is a key issue that restricts its large-scale application. In order to break through international barriers and accelerate the process of mass production of heptafluoroisobutyronitrile, this paper reviews the preparation technologies of heptafluoroisobutyronitrile at home and abroad, introduces in detail the research overview of traditional and new preparation technologies, elaborates on the reaction processes of various preparation technologies, reveals the differences and advantages and disadvantages between various preparation methods from the aspects of raw material toxicity, reaction conditions, reaction equipment, and product yield, proposes a new method for preparing heptafluoroisobutyronitrile with industrial production potential, and makes prospects for the development of heptafluoroisobutyronitrile preparation technology.
This standard specifies the technical requirements, sampling, testing methods, inspection rules, as well as labeling, packaging, filling, transportation, storage, and safety information for heptafluoroisobutyronitrile.
Suitable for the production, inspection, and use of heptafluoroisobutyronitrile.
This standard provides detailed technical requirements and related operating specifications for heptafluoroisobutyronitrile, covering all stages from production to use. By clarifying sampling, testing methods, and inspection rules, ensure the stability of product quality ..
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the "Shimadzu packed chromatography column application for determination of heptafluoroisobutyronitrile", which has high column efficiency, good separation, and good separation. It has been installed and used on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE with good results.
