Three types are known: antimony(III) chloride, antimony(V) chloride, and antimony nonachloride. [Antimony(III) chloride] Also known as antimony trichloride. Chemical formula: SbCl 3 . Colorless, prismatic or octahedral crystals. It can be obtained by reacting chlorine directly with antimony, or by dissolving stibnite Sb 2 S 3 in hydrochloric acid, concentrating it, and distilling it. Melting point: 73.4°C, boiling point: 223°C, specific gravity: 3.14 (20°C). It is highly deliquescent and often becomes a viscous semi-liquid if left untreated, and has long been known as antimony butter. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
塩化アンチモン(III),塩化アンチモン(V),九塩化アンチモンの3種が知られている。 [塩化アンチモン(III)] 三塩化アンチモンともいう。化学式SbCl3。無色柱状または八面体の結晶。アンチモンに直接塩素を反応させるか,輝安鉱Sb2S3を塩酸に溶かして濃縮し,蒸留しても得られる。融点73.4℃,沸点223℃,比重3.14(20℃)。潮解性が強く,放置すると粘い半液状となることが多く,アンチモンバターの名で古くから知られている。 出典 株式会社平凡社世界大百科事典 第2版について 情報 |
