  一系列饱和α-支链脂肪酸的合成和低温性能得到改善

  摘要：

  五种饱和的α-支链脂肪酸，也称为Guerbet酸，包括α-丙基己酸（G 1），α-丁基己酸（G 2），α-丙基辛酸（G 3），α-丁基辛酸（G 4）通过四步反应以高收率合成了α-己基辛酸（G 5）。获得了无色，几乎无味和油状的高纯度产品，其结构已通过GC，1 H / 13 C NMR和ESI-MS表征得到了证实。G 1，G 3和G 4的倾点低于-60°C，而 G 2和G 5由于具有分子对称性，因此显示出较高的倾点（分别为-42°C和6°C）。考虑到低温性能，G 1，G 3，G 4甚至G 2在润滑剂和油田中具有巨大的潜在应用。

  An environmentally-friendly solid catalyst component for olefin polymerization exhibits high hydrogen activity and high polymerization activity, can produce a polymer that exhibits a high MFR and high stereoregularity in high yield using a small amount of hydrogen, and exhibits high copolymerization activity and excellent copolymerization properties (e.g., block ratio). The solid catalyst component for olefin polymerization is produced by bringing (a) a magnesium compound, (b) an internal electron donor, and (c) a tetravalent-element halogen compound into contact with each other in an inert organic solvent, the internal electron donor (b) being represented by R12C(COOCH3)2 (wherein R1 is selected from a branched alkyl group having 3 to 20 carbon atoms, a halogen atom, a linear or branched halogen-substituted alkyl group having 2 to 20 carbon atoms, a linear alkyl group having 1 to 20 carbon atoms, a cycloalkyl group having 3 to 20 carbon atoms, a vinyl group, and an allyl group).
