摘要
介绍了亲核取代氢(VNS)胺化原理,概述了VNS胺化合成TATB、DADNB、DATB、DATNT、CL 14、LLM 116、LLM 119等炸药的研究进展。详细讨论、分析和比较了VNS胺化合成TATB的多条路线。并对VNS胺化法在炸药合成领域的进一步应用进行了展望。
The basic principle of VNS (Vicarious Nucleophilic Substitution of Hydrogen) is introduced. Progress in synthesis of TATB,DADNB,DATB,DATNT,CL-14,LLM-116,LLM-119 by VNS amination are reviewed. The prospect of VNS amination in synthesizing explosives is discussed. A number of VNS amination routes for preparing TATB are discussed,analyzed and compared in detail. Conversion of picramide to TATB using hydroxylamine as the VNS aminating (reagent) is probably the cheapest way. LLNL has achieved an excellent results with high yield,high purity,higher reactant concentrations, petter product appearance without halide contamination in TATB using ATA as the VNS aminating reagent.
