摘 要:针对大学本科"过氧化钙的制备及含量测定"实验中存在的耗时长、产率低和氨水污染等问题,采用CaCl2和H2O2为主要原料,以NaOH溶液代替氨水作为反应介质,对试剂浓度、反应温度、加料顺序等各种影响因素进行了深入研究,从而总结出最佳实验条件,制备出产率高、纯度好、性能稳定的产品,为"无机制备"课程开设该实验提供了一套成功率高、效果好的实验方案.T his article is aimed at the experim ent^ problem of The Preparation and Content Determinationo f Calcium Peroxide for college undergraduate, which has disadvantages like long tim e consum ing, lowyield and the pollution of anm onia w ater etc. Calcium chloride and hydrogen peroxide w ere used as them ain reaction reagents. Sodium hydroxide, replaced am m onia w ater, w as adopted as reaction m edium inthe laboratory. All the influential factors w ere studied by the m ono-factor experim ents, such as reagentconcentration, reaction tem perature and reagent addition order. T he m ethod w as prepared w ith high yield,good purity, stable perform ance of p ro d ucts; w hich provided the course Inorganic P reparation w ith a reliableand effective scheme.
