摘要:Ru(0)纳米粒子的水悬浮液,用羟乙基铵盐稳定并具有大约2 Nm的大小,被证明在纯净水中在叔丁基过氧化氢存在下在α-Pine烯的轻度氧化中具有活性和选择性.获得了对精细化学非常感兴趣的产品马鞭草酮,它是在优化的条件下收率高达41%的主要产品.已确定2-羟基-3-吡喃酮酮是反应的副产物,但含量极低(<7%).动力学研究可以确定潜在的反应中间体和副产物.此外,用自由基清除剂进行的机理研究证实,α-Pine烯氧化主要是指以碳和氧为中心的自由基.

标题 :Controlled free radical agent for nanocomposite synthesis
发明人：PARKER DANE KENTON
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention relates to a process for producing a free radical control agent of the structural formula: n nwherein Z is selected from the group consisting of n nwherein R 1 is an alkyl group of 1 to 4 carbon atoms, cyclohexyl or phenyl; wherein R 2 is an alkoxy group of 1 to 8 carbon atoms or a cycloalkoxy group of 5 to 8 carbon atoms; wherein Alk is a divalent hydrocarbon of 1 to 18 carbon atoms; and wherein Y represents a functional group that is capable of activating a vinylic carbon toward free radical addition; said process comprising the steps of (1) reacting a mercaptosilane of the structural formula: Z-Alk-SH with carbon disulfide in the presence of a phase transfer catalyst and an alkali metal hydroxide to produce a trithiocarbonate salt; and (2) reacting the trithiocarbonate salt with a halogen containing compound of the structural formula X-Y to produce the free radical control agent, wherein X represents a halogen atom. Such free radical control agents are capable of covalently bonding to silica/silicate surfaces and are of particular benefit in producing rubbery compounds that will be loaded with silica fillers, such as tire tread rubbers.
