Section 3: Hazards Identification
Soluble oxalates are harmful if swallowed. They precipitate calcium from the bloodstream causing violent
Emergency Overview:
muscular stimulation, convulsions, collapse, and death.
Primary Routes of Exposure:Ingestion
Eye Contact:May cause moderate to severe irritation of the eyes.
Skin Contact:May cause moderate to severe irritation of the skin.
Inhalation:May be severely irritating to the nose, mucous membranes and respiratory tract.

生态学数据:

该物质对环境可能有危害,对水体应给予特别注意。

将0.3g Tm(NO3)3溶于200mL水中,加入2mL 6mol/L的硝酸,然后加入40mL溶有3g草酸甲酯的水溶液。充分混合后,回流3h,即析出草酸盐沉淀。室温放置过夜再进行过滤,依次用水、乙醇和乙醚洗涤,生成结晶在室温风干,得六水合物。
