锰蔷薇辉石的合成及其在酸中的溶解性

Synthesis of Rhodonite and Its Solubility in Various Acids

摘要: 本文报导了一种人工合成及鉴定纯锰蔷薇辉石的方法。合成的锰蔷薇辉石在室温时可被稀酸分解约20%。在非常温下(约100℃)可被稀盐酸分解57%以上。用量热计测得室温时锰蔷薇辉石与稀盐酸反应的反应热是-85.1±3.6kJ·mol^-1。

Abstract: In this paper, the method of synthesis and charaterization of pure rhodonite are discussed.At room temperature about 20% by dilute acid, and at about 100℃ more than 50% by dilute hydrochloric acid can be decomposed. It is found by calorimetry that reaction of rhodonite with hydrochloric acid releases the heat to be 85.1±3.6kJ/mol.
