• Process for making allylic esters of tetrabromophthalic acid
  申请人：FMC Corporation

  公开号：EP0075289A1

  公开（公告）日：1983-03-30

  Allylic esters of tetrabromophthalic acid are formed using allylic alcohol both as a reactant and a solvent. In the first step, the alcohol and a base are reacted with tetrabromophthalic anhydride to form the half-ester sodium salt. In the second step, the half-ester sodium salt is reacted with allylic halide to form the diester which crystallizes from solution. The excess solvent may be treated to recover the raw materials or recycled.

  四溴邻苯二甲酸的烯丙基酯是用烯丙基醇作为反应物和溶剂形成的。 第一步，醇和碱与四溴邻苯二甲酸酐反应生成半酯钠盐。 第二步，半酯钠盐与烯丙基卤化物反应生成二酯，二酯从溶液中结晶。 过量的溶剂可通过处理回收原材料或循环使用。
