Antimony Trioxide and Antimony Trisulfide
(a) Production. Antimony trioxide is typically produced by roasting stibnite ores, which are reported to contain 55% antimony. The production of antimony trioxide occurs as a vapour-phase reaction at temperatures in excess of 1550°C. The stoichiometric addition of oxygen to the feed ore produces the desired product.
Features of Antimony Trioxide as Catalysts | Nihon Seiko Co., Ltd.
Antimony compounds are excellent catalysts to accelerate the polymerization in polyester manufacturing. Antimony trioxide is the most widely used polymerization catalyst in both domestic and overseas markets in the manufacture of polyethylene terephthalate(PET)from ethylene glycol(EG)and high purity terephthalic acid(TPA), or dimethyl terephthalete(DMT).
