摘 要: CH_3CONH_2-H_2C_2O_4二元系的DSC研究黎厚斌,熊亚,胡起柱,屈松生(武汉测绘科技大学,武汉大学武汉430070)关键词相图,DSC,X-射线,H_2C_2O_4,CH_3CONH_2前言Ben.H.Peterson[1]早在1933年就研究... The DSC (Differential Scanning Calorimently) method was used to study phase diagram of binary system CH_3CONH_2-H2C2O4. Experimental results show that there is a new congruently melting compound CH_3CONH_2· H_2C_2O_4 in the system,this result is also veritied by X-ray. CH_3CONH_2-CH_3CONH_2·H_2C_2O_4 behaves as a eutectic system, its eutectic occurs at 50℃、30% H_2C_2O_4、70% CH_3CONH_2;the CH_3CONH_2·H_2C_2O_4-H_2C_2O_4 behaves as a eutectic system too,its eutectic occurs at 112℃、76% H_2C_2O_4、24% CH_3CONH_2.
