通过对蔚县煤田岩相古地理及古构造的分析 。
Analysis on the lithofacies and paleogeography & the paleostructure in Yuxian coalfield,it's origin and the influence of the paulopost composition are known. Key words:lithofacies and paleogeography;paleostructure;coal-control structure., Fuyang 236032,China;2.Department of Chemistry,Fuyang Teacher's College, Fuyang 236032,China) Abstract:Beet alkali was synthesized from trimethylamine and chloroacetic acid. The effects of primary factors on the yield and the purity of product were discussed, under the optimum conditions ,the yield and the purity of beet alkali can reach 90.3% and 99.1%, respectively. The process has these advantages which are simplified operation, easy drying ,high yield,high purity, low cost and easy application and dissemination et al.
