一般描述
氯化铪，又名四氯化铪，常用作前体生产铪金属和各种铪化合物。还用作某些有机合成反应的催化剂。因其反应性和湿度敏感性，氯化铪通常在惰性环境中处理。
应用
氯化铪用处：
- 作为前体合成磷酸铪锂，因其高离子导电性和化学稳定性而用作锂电池的固态电解质材料。
- 作为催化剂用于各种羰基化合物（包括醛和酮）的缩醛化反应。
- 作为催化剂用于羧酸与醇的直接酯化缩合反应。
- 作为锂和钠离子电池的高容量正极材料。

The feasibility of a previously established method based on ozonolysis and hydrogenation reactions for the production of 9-hydroxynonanoic acid from oleic acid has been demonstrated. Metal catalyzed lactonization conditions have been used to convert 9-hydroxynonanoic acid into 1,11-dioxacycloicosane-2,12-dione, which is
