when accessing to the by-product, the speed of replacement reaction is choked back and soil exchangeable sodium can not immediately discharged soil.
当加入脱硫副产物后,置换反应的速度受到抑制,土壤中的代换性钠也不能立即排出土体。
therefore the separation method of replacement reaction by cupric salt is not suitable for phase separation in the chemical phase analysis of metallurgic products.
因此,铜盐置换分离法不适用于冶金产品的化学物相分析。
and is was found the degree of replacement reaction increased with the advance of time and temperature in raction.
在合成时,反应温度越高,反应时间越长,亲核取代反应越完全。
the preparation method of potassium pentaborate (kb5o8) was studied with the replacement reaction between potassium chloride and sodium pentaborate solution.
