摘　　要：采用氯化铵和氧化铈为原料,利用自制成套氯化装置干法制备无水氯化铈,实现了无水氯化铈的批量生产。扩大试验结果表明:在氧化铈50 kg,氯化铵用量为理论量的2.4倍,均匀混料,反应温度450℃,反应时间32 h,料层厚度15 cm的条件下产品无水氯化铈纯度可高达99.35%。The preparation of anhydrous cerium chloride was studied using ammonium chloride as chlorinating agent. The results show that the technology using self-developed chlorination system can achieve anhydrous cerium chloride batch production of anhydrous cerium chloride. Under the optimal conditions： cerium oxide being 50 kg, ammonium chloride dosage being 2.4 times of the theoretical amount, uniform mixing, at 450℃ , reaction time being 32 h, material layer thickness of 15 cm, the product purity was 99.35%.
