摘 要:本文使用了自制的热重分析设备研究了在各种HCl-H2O-N2混合气氛下各种氯化镁水合物的行为,并参考文献数据,提出了各有关的脱水和水解反应的平衡数据与温度的关系式。
Abstract: Equipment for thermogravimetric analysis in corrosive atmosphere is des cribed-This equipment is used to study the behaviour of the hydrates of mag nesium chloride in HCl-H2O-N2 atm. of various compositions. With proper man oeuvre, the equilibrium conditions between the various phases are established. With the help of literature survey, the free energy changes of the various dehy dration and hydrolysis reactions of MgCl2 hydrates are established.
