structure. The top layer is sacrificial and serves two functions: (1) sealing of intercrystalline defects from transport and (2) reduction of the loading on the underlying layer to prevent transport ofo-xylene.Silicaliteon ZSM-5 proved to be the optimum layer combination inpervaporationtesting, ...
Structure and thermal decomposition of para- and ortho-xylene on Pt(111): a HREELS, LEED and TPD studyHigh resolution electron energy loss spectroscopy (HREELS), thermal desorption spectroscopy and low energy electron diffraction (LEED) were used to investigate the low temperature adsorption structure...
ortho-Xylene (1,2-dimethyl-benzene, o-xylene, or OX) is an aromatic compound that is commonly derived from crude oil sources. It is found in the mixed xylenes stream, which is a mixture of ortho-xylene, metaxylene (MX), and para-xylene (PX). While very similar in structure, these...
18.The catalytic activity declined as the selectivity of paraxylene and ortho-xylene improved with increasing treated temperature. 随着处理温度的提高,催化剂的活性降低,对二甲苯和邻二甲苯的选择性上升。 19.The Sketchup model is finalized and then Kemp returns to Photoshop to create a deliverable ortho...
Using B3LYP density functional theory in conjunction with the 6-311++G** basis set, the relative rates of the initial rate-determining attack of ozone upon the carbon€"carbon bonds of o-xylene are found to be 4,5- 3,4- > 2,3- > 1,2-. With the assumption that the final products...
