环保绝缘气体七氟异丁腈(C4F7N)的制备技术现状与发展
Current Status and Development of Preparation Technology of Environment Friendly Insulating Gas Heptafluoroisobutyronitrile (C4F7N)
摘要
Abstract
Heptafluoroisobutyronitrile is considered to be an attractive alternative gas of SF6 because of its excellent insulating properties and low GWP. However, heptafluoroisobutyronitrile has not been industrially produced, and the preparation technology is the crucial problem that restricts its large-scale application. In order to break through the international barriers and accelerate the process of localization, the preparation technology of heptafluoroisobutyronitrile at home and abroad is reviewed and the research of traditional and new progress is introduced in detail with the reaction process of various method described. From the angle of the comparison of raw material toxicity, reaction conditions, reaction equipment and product yield, the preparation methods with industrial production potential are proposed, and the development of preparation technology of heptalfluoroisobutyronitrile is prospected.关键词
