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: (If dust) May be severely irritating to the nose, mucous membranes and respiratory tract.
Ingestion: Ingestion may cause vomiting, pain, violent muscular stimulation, convulsions, collapse, and death.
Soluble oxalates remove calcium from the bloodstream. This interferes with the central nervous system

制备方法与用途

制备方法

将0.3克Nd(NO3)3溶于200毫升水中，加入2毫升6摩尔/升的硝酸，然后加入40毫升含3克草酸甲酯的水溶液。充分混合后，回流3小时，即会析出草酸盐沉淀。室温下放置过夜后再进行过滤，并依次用水、乙醇和乙醚洗涤。生成的结晶在室温下风干后得到九水合物。
