Asymmetric autocatalysis occurs when a chiral product operates as an asymmetric catalyst for its own production 摘要不对称自催化是指由不对称反应生成的手性产物自身作为催化剂的反应过程。
Metallic and other inorganic coatings - automated controlled shot - peening of metallic articles prior to nickel , autocatalytic nickel or chromium plating , or as a final finish 金属和其他无机覆层.金属制品镀镍自催化镀镍或镀铬或精饰前的自动控制喷丸处理
Asymmetric autocatalysis intrinsically has the following advantages : chiral amplification of production , high reaction efficiency , easy purification of the products , consecutive reaction , which is a new aspect of chiral synthesis 不对称自催化具有手性自动放大、反应活性较高、产物处理较易、反应体系连续等特点，是不对称化学的一个新的领域。
