Antimony triacetate Specification

The Antimony triacetate, with the CAS registry number 6923-52-0 and EINECS registry number 230-043-2, has the systematic name of antimony(+3) trihydride cation triacetate. It belongs to the following product categories: Antimony Salts; Antimony Metal and Ceramic Science; AntimonyMicro/Nanoelectronics; Catalysis and Inorganic Chemistry; Chemical Synthesis; Salts; Solution Deposition Precursors. And the molecular formula of this chemical is C6H12O6Sb.

The Antimony triacetate is the antimony salt of acetic acid, and it is a kind of white powder which is usually used as catalyst in the production of synthetic fibers and the fasculation of polyester.What's more, Antimony triacetate can be prepared by the reaction of antimony(III) oxide with acetic acid:
Sb2O3 + 6 HC2H3O2 → 2 Sb(C2H3O2)3 + 3H2O

The physical properties of Antimony triacetate are as following: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: Å2; (5)Density: 1.22 g/cm3 at 20°C; (6)Melting point: 127 °C, 400 K, 261 °F.

You should be cautious while dealing with this chemical. It is harmful by inhalation and if swallowed, and may cause burns. It is also toxic to aquatic organisms, and may cause long-term adverse effects in the aquatic environment. Therefore, you had better take the following instructions: Wear suitable protective clothing, gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible); Avoid release to the environment. Refer to special instructions safety data sheet.
