摘要:制备了中离子型 5,5â²-叠氮双(1,3-二苯基四氮唑)1,并通过化学氧化得到了相应的自由基阳离子 1ë+ 和二阳离子 12+ 的稳定晶体,这些晶体在用锌还原时可逆地还原出叠氮 1.在吡啶(py)或二氯甲烷(dcm)中使用环形伏安法和差分脉冲伏安法对 1 进行的电化学研究也揭示了通过自由基阳离子 1ë+ 导致双阳离子 12+ 的两个可逆的连续单电子氧化过程,这两个过程都可以还原成中性态 1.在阴极过程中,1 通过两次连续的单电子转移被还原,在电位略有不同的情况下还原到相应的二价离子 12â,后者又可被还原到中性状态;从而构成了一个可逆的四级氧化还原体系.辐射阳离子 1ë+ 和阴离子 1ëâ 通过 Epr 光谱进行了表征.为了更深入地了解 1ë+ 的自旋密度分布,合成了双 15N 标记和四 15N 标记的 1Aë+,1Bë+ 和 1Cë+,并通过 Epr 和 15N 以及 14N Endor 光谱进行了研究.根据 1H Endor,似乎存在与两个苯基环的质子之间的微小耦合,但这在 Epr 光谱中无法解析.在阴极过程中,观测到了 9 和 10 的还原峰,这是由于它们被可逆地单电子还原成了相应的自由基阴离子.通过 Epr 光谱对还原 10 得到的自由基进行了表征.另一方面,5â8 可以通过形式上的双电子转移被还原成相应的二元离子,这些二元离子可以再氧化成中性状态.在阳极过程中,9/10 经历不可逆的单电子氧化,而 5/6(在 Dcm 中)和 7/8(在 Py 中)则经历可逆或不可逆的一步步双电子氧化,最终生成二阳离子.在 Py 中,5/6 的氧化产物反应生成更多的物种,显示出另外两个氧化峰和几个还原峰.另一方面,7/8 的氧化产物在 Dcm 中不稳定(一个主要的氧化峰和还原峰).电化学数据将从阳离子的脱ocalization 和阳离子的共轭作用两个方面进行讨论.

标题:One-pot synthesis of nanoparticles and liquid polymer for rubber applications
发明人：WARREN SANDRA
权利人:BRIDGESTONE CORP
摘要:A method for performing a one-batch synthesis of a blend of nanoparticles and liquid polymer includes polymerizing a first monomer and optionally a second monomer in a hydrocarbon solvent to form the liquid polymer. The polymerization is terminated before completion with a quenching agent. Then a charge of polymerization initiator, and a mixture of multiple-vinyl aromatic monomer and mono-vinyl aromatic monomer are added. This causes further polymerization whereby nanoparticles are formed in situ having a core including the multiple-vinyl aromatic monomer, and a shell including the first monomer or the first monomer and the second monomer. Liquid polymer/nanoparticle blends resulting from the method and rubber compositions incorporating the blends are also disclosed.

发明人：WILSON LAWRENCE JOSEPH
权利人:PROCTER & GAMBLE
摘要:The subject invention involves novel acyl isothiocyanate resins of formula (I) and processes for making them: (a) starting with a phenyl carboxy resin, treating the resin with any reagent that converts the carboxy to an acyl halide, followed by treatment with tetranikylammonium thiocyanate or an alkali metal salt thereof, to provide the acyl isothiocyanate resin. The subject invention also involves processes for making guanidine compounds and related cyclized compounds using an acyl isothiocyanate resin, comprising the following steps: (b) reacting the acyl isothiocyanate resin with a primary amine; (c) reacting the product from Step (b) with a sulfur activating agent and ammonia or a primary or secondary amine; (d) treating the product from Step (c) with a strong base or medium strength acid to cleave product from the resin, providing the guanidine compound or/and the related cyclized compound.

标题:Synthesis of polyether polyols based low dosage gas hydrate inhibitors using double metal cyanide catalyst

权利人:COUNCIL SCIENT IND RES
摘要:A series of different metals (Zn/Fe/Co/Sn/Mg/La/Al/Cr) based double metal cyanide (DMC) catalyst is disclosed herein. Benzene-1,3,5-tricarboxylic acid (BTC) is incorporated as an organic complexing agent (CA) in the DMC catalyst. The DMC catalysts prepared with BTC and its derivatives as CAs are highly active towards ring opening polymerization (ROP) of propylene oxide (PO) and imparts heterogeneity as compared to the DMC prepared without any CA. The polyether polyols (PEPOs) with controlled molecular weight (Mw), polydispersity index (PDI), hydroxyl value (OH), and iodine value (I2) are produced using a DMC catalyst. PEPOs of the present invention relate to low-dosage gas hydrate inhibitors (LDHIs) utilized to mitigate/manage the formation, growth, and deposition/agglomeration of gas hydrate crystals in oil and gas production pipelines (especially applicable to deep and ultra-deep developments), and drilling or fracturing operations during natural gas hydrate exploration.
