生产制备方法及用途展开↓

合成制备方法


 1.由氧化铋或氢氧化铋溶于氢氟酸水溶液而得。   

2.将五水合硝酸铋的结晶48.5g与甘露醇7.5g用研钵充分混合,调成膏状后,加水250mL使其溶解,过滤除去不溶物。将所得溶液加到54g氢氧化钾溶于250mL水制得的溶液中,将该溶液用稀硫酸中和至稍显碱性的程度。将所得到的沉淀过滤分离,用水洗涤,至洗涤液中无硫酸根离子后,将此沉淀加到聚乙烯烧杯内预先准备的25%的30g氢氟酸中,因为生成膏状物,故可充分搅拌放冷,过滤分离。将滤纸上的滤饼移至铂皿中,在水浴上加热蒸发至干后,在100℃干燥粉碎,可得约20g的白色三氟化铋。

用途


制备五氟化铋。

物化性质展开↓

外观与性状:
白色晶体或结晶粉末
密度:
8.3
熔点:
727ºC
折射率:
1.74
存储条件/存储方法:

 本品应密封保存。

稳定性相关:

有α型和β型两种,用上述方法制得者为α型,如果将α型加热至220℃,就可转变为β型。熔点为725~730℃。如果加热至900℃,就有相当程度的蒸发。难溶于水及氟化氢水溶液。利用氢氧化铋与过量的氟化氢反应,可制得吸湿性强的酸式盐BiF3·2HF。酸式盐水解即可变为BiOF·2HF,如果进一步加热,即变为BiF3及BiOF。

Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
The toxicological properties of this material have not been fully investigated.
Potential Health Effects
Eye:
No information regarding eye irritation and other potential effects was found.
Skin:
No information regarding skin irritation and other potential effects was found.
Ingestion:
The toxicological properties of this substance have not been fully investigated. Inorganic fluorides can be harmful. Acute exposure to fluorine compounds can lead to digestive tract burns, and abdominal pain. May cause fever and rheumatic pain.
Inhalation:
The toxicological properties of this substance have not been fully investigated.
Chronic:
Chronic inhalation and ingestion may cause chronic fluoride poisoning (fluorosis) characterized by weight loss, weakness, anemia, brittle bones, and stiff joints. Repeated or prolonged exposure may cause a bismuth line or black spots on the gums, foul breath and salivation. Chronic exposure to fluoride compounds may cause systemic toxicity.

Section 4 - FIRST AID MEASURES
