  2-Methylheptadecane (I) is the sex pheromone of the family Arctiidae (tiger moth) and was isolated by Roelof and Carde and assigned structure I on the basis of spectral data. Haque et al. isolated a granular white solid (m.p. 80 °C) from the ether extract of dried and powdered plant of Parthenium hysterophorous L. (Compositae) and proposed its structure, 14-methylpentadecan-3-one (II) on the basis of spectroscopic data. We report herein a short and facile synthesis of these compounds.

  Co/H‐ZSM‐5 zeolites were prepared by a surface organometallic chemistry grafting route, namely, by the stoichiometric reaction between cobaltocene and the Brønsted acid sites in zeolites. The catalyst was applied to a model reaction of the catalytic hydrodeoxygenation of stearic acid (SA). The cobalt species existed in the form of isolated Co2+ ions at the exchange positions after grafting, transformed to

  双功能Co / H-ZSM-5分子筛是通过表面有机金属化学接枝途径制备的，即通过钴茂金属与分子筛中布朗斯台德酸位点之间的化学计量反应制备的。将该催化剂用于硬脂酸（SA）的催化加氢脱氧的模型反应。钴物种以孤立的Co 2+形式存在接枝后在交换位置处的离子，转化为沸石表面上的CoO物种，在空气中煅烧后稳定在沸石通道内部，最后被氢还原为大小约为1.5 nm的金属钴物种的均质簇。在此过程中，保留了H‐ZSM‐5沸石的布朗斯台德酸点，但酸度略有降低。所制备的双功能催化剂对SA的加氢脱氧（2.11 g SA  g cat -1  h -1）的活性比通过固相法制备的参比催化剂（0.13 g SA  g cat -1  h -1）高约16倍。态离子交换和高C 18/ C 17比率约为24。双功能Co / H-ZSM-5的显着加氢脱氧性能归因于均匀的金属钴簇与H-ZSM-5中的布朗斯台德酸位之间的有效协同作用。还研究了制备的双功能Co
• Role of support in deoxygenation and isomerization of methyl stearate over nickel–molybdenum catalysts

  日期：2014.6

  Microporous SAPO-11 and highly ordered mesoporous AISBA-15 with different aluminum contents (with Si/Alratio of 5 and 10) were synthesized. Thus prepared samples were characterized by BET, pyridine-FT1R and NH3-TPD to investigate their structural and acidic properties. The samples were then transformed into bifunctional catalysts by loading with molybdenum and nickel. Their activities were tested in the hydroconversion of methyl stearate using a fixed bed flow reactor system. The sulfided NiMo catalysts exhibited high conversion and deoxygenation activities. High isomerization activities observed for both NiMo/SAP0-11 and NiM0/AISBA-15 catalysts, similar to the isomerization of light naphtha, was attributed to the acidity of supports. However, the acidity of supports was not the only factor influencing the isomerization of long chain molecules. A1SBA-15 had a large specific surface area that contained more acidic sites inside of its channels, promoting the formation of cracking products; SAPO-11 had a suitable pore size and contained fewer acidic sites inside the pore channels, promoting the formation of mono-branched isomers while suppressing cracking reactions.
