| Alkyl Aluminum Series Products | In 2023,Deshang Chemicals adopted the self-developed advanced production technology to design and build alkyl aluminum series products with an annual output of 2,000 tons.Alkyl aluminum series products include: triisobutyl aluminum,diethylaluminum chloride,dichloroethyl aluminum and ethylaluminum sesquichloride (The design production capacity is 500 tons for each kind of product). Trisobutyl aluminum is mainly used as a polymerization catalyst of butadiene rubber,synthetic resin,synthetic fiber and olefin polymer,and can also be used as an intermediate of organometallic compounds as wellas a high-energy raw material and reducing agent of jet engine ignition system. Diethylaluminum chlorideis mainly used in the synthesis of polyolefin,butyl rubber,ethylene propylene rubber polymerization catalyst and organometallic compounds as wellas pharmaceutical intemediates. Dichloroethyl aluminumis mainly used as a catalyst for olefin polymerization and aromatics hydrogenation,and also used as a co-catalyst in the production of polypropylene. Ethylaluminum sesquichloride is mainly used as the traditional Ziegler-Natta catalyst components and the intermediates in the production of alkyl aluminum series products. | ||
