Addition of inert gases (He, A, N-2 and SF6) increased W-max thus suggesting that this rate is governed by a diffusion controlled process at the walla of the reaction vessel. Studies of the competitive oxidation of binary mixtures of the xylenes indicated that the chain propagation reactions...
Aromatic hydrocarbonsare the best polymerization solvents. The rate of polymerization decreases in the order benzene>toluene>xylenes, inversely with thebasicityof the solvent.117,296Hexamethylbenzene, a strongelectron donor, is capable of inactivating the polymerization if present in a suitable amount. Al...
Isomer-specific product detection of gas-phase xylyl radical rearrangement and decomposition using VUV synchrotron photoionization. Xylyl radicals are intermediates in combustion processes since their parent molecules, xylenes, are present as fuel additives. In this study we report on t... P Hemberger,...
The rate of polymerization decreases in the order benzene > toluene > xylenes, inversely with the basicity of the solvent.117,296 Hexamethylbenzene, a strong electron donor, is capable of inactivating the polymerization if present in a suitable amount. Aliphatic solvents are also suitable, but ...
Influence of the cation composition on the dynamics of xylenes in X-type zeolites. Micropor. and Mesopor. Mat. 42, 135–155 (2001). 33. Barrett, C. Crystal Structure of Solid Hydrogen and Deuterium, and of Neon—Hydrogen and Neon—Deuterium Mixtures. J. Chem. Phys. 45, 834 (1966). ...
However, Y/S-D offered higher yield of xylenes, which have higher application value. In addition, the conversion obtained by using Y/S-D was 96.6% which was higher than those obtained by using Y/S-S (94.7%). This might be because the SBA-15 mesoporous phase of Y/S-D is Scientific...
Free-floating sections were mounted on gelatinized slides and dehydrated in graded ethanol and xylenes. Coverslips for all sections were secured in Prolong-gold anti-fade mounting media (Invitrogen). TUNEL staining was performed using the Roche TUNEL labeling kit per manufacturer instructions (Roche ...
13. The method of separating carbon nanotubes or fullerenes of claim 12, wherein the organic solvent is selected from the group consisting of chloroform, benzene, toluene, xylenes, dichlorobenzene, N,N-dimethylformamide, propyleneglycol, and methyl ether acetate. 14. The method of separating carbon...
A series of self-assembling terminally blocked tripeptides (containing coded amino acids) form gels in various aromatic solvents including benzene, toluene, xylenes at low concentrations. However these tripeptides do not form gels in aliphatic hydrocarbons like n-hexane, cyclohexane, n-decane etc. ...
or high molecular weight polyester polymer in the nonreactive carrier; and applying a vacuum to remove the xylenes from the syrup and form a solid (which may be in the form of a powder or subsequently formed into a powder) that includes the medium or high molecular weight polyester polymer....
