Application:
Di-tert-butyl Polysulfide is widely & mainly used as cracking furnace tube coking inhibitor & sulfiding hydrotreating and hydrocracking catalysts. To replace DMDS in refineries, equivalent to TBPS 454 & TPS 44.
Also used as additive of industrial lubricants for automotive gear oils and greases.
Characters of Di-tert-butyl Polysulfide:
(1) The flash point (open cup) of this product is as high as 100'C, which is significantly higher than that of dimethyl disulfide (DMDS), so to leads to a safer storage, transportation, injection handling and other characteristics. In addition, the product does not require a water seal for storage, it is a non-hazardous item.
(2) Compared with dimethyl disulfide (DMDS), it is not easy to volatilize under normal temperature and pressure, and has only a light smell when loading and unloading, no unpleasant smell, so the operating environment is friendly.
(3) The decomposition temperature of this product is lower than that of dimethyl disulfide (DMDS), and the decomposition temperature range is wide. It is easy to be adsorbed by the catalyst, and the adsorption effect is better. A certain molecular weight distribution can effectively protect the hydrogenation catalyst from being thermally deactivated during the heating process.
(4) The appearance of the product is a dark brown liquid, and it is easy to judge and verify the injection volume through the liquid level gauge during the vulcanization process.
(5) This product has the environmental protection concerns of saving hydrogen consumption and reducing sulfide emissions.
Usual Packing:
210kg net 200L drum; 1100KGs net IBC tank, 24MTs net ISO-TANK or tank car by customer's requirement.
Storage:
It is non-hazardous item, in a cool, dry, and well-ventilated area, shelf life of 2 years in sealed original packing.
