摘　　要：本文主要介绍了合成嗯哇烷的新方法和它们的柱性研究。在合成中，避免了溶剂苯的蒸馏过程。仅用简单的溶剂革取法就能方便地提取出苯中９０％以上的想唑烷，苯则可以返回到合成中循环使用，这给工厂大生产带来了极大的方便。在效性研究方面，测定了经数种唑烷躁制试验后，样皮的收缩温度Ｔｓ。This paper is about a new method of synthesis oxazolldines and discusses their tanning properties. In the preparation, the method avoided the distillation of benxen as a solvent. It applied a simple way of extraction to give the oxazolidines above 90%. The used benxen can be made use of as solven again. The improvement of the preparation is a vary convenient for the Industry. On the tanning property, the Ts value if several oxazolidines was determined,the relation Ts to PH and to the concentration of the oxazolidines, or to time was also difined
