硝酸鈦是一種化學性質活潑的無機化合物,化學式為Ti(NO3)4

製備

與原本的製備方法類似,[7][8]硝酸鈦可以由五氧化二氮[9]硝酸氯[10]四氯化鈦反應製得。[4]

水合硝酸鈦 [Ti(H2O)6](NO3)3則可以由鈦化合物溶於硝酸中而成。[11]

結構

硝酸鈦的對稱群是D2d,有四個二齒的硝酸根配體,其中的N-O鍵長為1.29 Å(配位)和1.185 Å(非配位)。[6]

性質

硝酸鈦可溶於非極性溶劑四氯化矽和四氯化碳。[12][8]

硝酸鈦具有吸濕性,會轉化為不明確的水合物。[13]無水硝酸鈦的反應性很高,甚至會和碳氫化合物反應。[13]它也會和正十二烷[14]對二氯苯苯甲醚聯苯反應。[14][15]

硝酸鈦受熱分解成二氧化鈦[16]
