Abstract A lab scale two staged hot rod reactor was constructed to stimulate the two staged downdraft biomass gasifier. The present study focused on the heterogeneous conversion of the pyrolysis tars over biomass char. A typical Chinese agricultural waste, the rice straw, was chosen for the raw material and the source of the biomass char. Effects of the temperature, the presence of the char and pretreatments of the char, including the water washed char and the char added with K2CO3 powder, on the pyrolysis tar removal were investigated. The products of tars were qualitatively and quantitatively analyzed. The evolution of the inner pore structure of chars with different temperatures and residence times was also investigated. The char bed condition exhibited higher tar conversion efficiency than the thermal cracking condition. The results indicated that the presence of the char could catalytically promote the formation of alkyl monoaromatics and meanwhile inhibit the formation of PAHs (polycyclic aromatic hydrocarbons) from the primary tars. The alkali metal elements might play a key role for the catalytic effect of the char. The appropriate increases in the temperature and the residence time for the char production could promote the development of the micro pores in chars.

A series of cerium complexes containing a 2,2?-methylenebis(6-tert- butyl-4-methylphenolate) (MBP2-) ligand framework is described. Electrochemical studies of the compound [Li(THF)2Ce(MBP) 2(THF)2] (1) reveal that the metal based oxidation wave occurs at -0.93 V vs Fc/Fc+. This potential demonstrates significant stabilization of the cerium(IV) ion in the MBP2- framework with a shift of ?2.25 V from the typically reported value for the cerium(III/IV) couple of E? = +1.30 V vs Fc/Fc+ for Ce(ClO 4)3 in HClO4 solutions. Compound 1 undergoes oxidation to form stable cerium(IV) species in the presence of a variety of common oxidants. The coordination of the redox-active ligands 2,2?-bipyridine and benzophenone to 1 result in complexes in which no apparent metal-to-ligand charge transfer occurs and the cerium ion remains in the +3 oxidation state.

Key points: Neurotransmitter release requires a tight coupling between synaptic vesicle exocytosis and endocytosis with dynamin being a key protein in that process. We used imaging techniques to examine the time course of endocytosis at mouse motor nerve terminals expressing synaptopHluorin, a genetically encoded reporter of the synaptic vesicle cycle. We separated two sequential phases of endocytosis taking place during the stimulation train: early and late endocytosis. Freshly released synaptic vesicle proteins are preferentially retrieved during the early phase, which is very sensitive to dynasore, an inhibitor of dynamin GTPase activity. Synaptic vesicle proteins pre-existing at the plasma membrane before the stimulation are preferentially retrieved during the late phase, which is very sensitive to myristyl trimethyl ammonium bromide (MitMAB), an inhibitor of the dynamin-phospholipid interaction. Synaptic endocytosis is essential at nerve terminals to maintain neurotransmitter release by exocytosis. Here, at the neuromuscular junction of synaptopHluorin (spH) transgenic mice, we have used imaging to study exo- and endocytosis occurring simultaneously during nerve stimulation. We observed two endocytosis components, which occur sequentially during stimulation. The early component of endocytosis apparently internalizes spH molecules freshly exocytosed. This component was sensitive to dynasore, a blocker of dynamin 1 GTPase activity. In contrast, this early component was resistant to myristyl trimethyl ammonium bromide (MiTMAB), a competitive agent that blocks dynamin binding to phospholipid membranes. The late component of endocytosis is likely to internalize spH molecules that pre-exist at the plasma membrane before stimulation starts. This component was blocked by MiTMAB, perhaps by impairing the binding of dynamin or other key endocytic proteins to phospholipid membranes. Our study suggests the co-existence of two sequential synaptic endocytosis steps taking place during stimulation that are susceptible to pharmacological dissection: an initial step, preferentially sensitive to dynasore, that internalizes vesicular components immediately after they are released, and a MiTMAB-sensitive step that internalizes vesicular components pre-existing at the plasma membrane surface. In addition, we report that post-stimulus endocytosis also has several components with different sensitivities to dynasore and MiTMAB.

In a Patent, authors is ，once mentioned of 10108-87-9

High yields of ester-substituted diary carbonates such as bis-methyl salicyl carbonate were obtained by the condensation of methyl salicylate with phosgene in the presence of a phase transfer catalyst (PTC) in an interfacial reaction system in which the pH of the aqueous phase was greater than 9.3. Using the method of the present invention conversions of greater than 99% were obtained whereas under standard conditions using triethylamine as the catalyst conversions were limited to 70-75% of the methyl salicylate starting material even with a 20 mole % excess of added phosgene. The optimized conditions of the of the present invention use only a slight excess of phosgene and represent an attractive route for the manufacture of bis methyl salicyl carbonate and ester-substituted diaryl carbonates generally.
