Ortho-xylene Ortho-xylene Alias: 1,2-Dimethylbenzene CAS No.: 95-47-6 Boiling point: 143-145 ℃ Lightning: 16 ℃ Appearance: colorless transparent liquid Packaging: 180KG/barrel iron barrel Uses: It can be used to produce phthalic anhydride, dyes, pesticides and medicines, such as vitamins,...
The provided preparation method for o-dibenzal chloride comrises: dissolving the o-xylene into inert solvent such as ortho-xylene or dichlorobenzene; leading Cl2 for reaction with catalyst; contrlling the proper conversion, speed and temperature; distilling to recover solvent and low-boiling point ...
19.24% power conversion efficiency is achieved for industrially compatible solvent ortho-xylene processed organic solar cells. Underlying morphological and photo-physical variation is revealed for device performance difference brought by solvent selection, which could set up a template for future research on...
Evaluation of an entrainer consisted of determining if the entrainer formed an azeotrope with meta-xylene, and if so the azeotropic composition, and the effect upon the relative volatility of the xylenes. If a 'mixture of the meta-xylene and the entrainer had a boiling point which was lower...
Clearly, there must be an activation energy barrier to overcome as heat is required for the conversion. The methyl group being an *ortho/para*-director would lead to the formation of 1,2- and 1,4- isomers. Thus, wouldn't these isomers also be the more thermodynamically stable isom...
. Note that if the point of attachment between the (Rv)rand U groups is shown to be fluid, then (Rv)rmay be attached to any available carbon of the U group. Note that when the point of attachment on the U group is shown to be fluid, the U group can be attached to the rest ...
of the ortho aromatic isomers is restricted due to the limited ability to effectively separate the ortho aromatic isomers from a mixture of aromatics, such as a mixture of C8aromatics which include at least one of para-xylene, meta-xylene, and ethylbenzene in addition to ortho-xylene. ...
xylene, cyclohexane, or n-hexane, carboxylic acid esters such as ethyl acetate or triethyl-orthoformic acid ester, and sesame oil, than the starting compounds. They can therefore be used in chemical reactions which proceed especially advantageously in such solvents, for example metallorganic reactions...
Hydrocarbon solvents (i.e. hydrocarbons used as solvents) include cyclic compounds such as benzene, xylene, cyclohexane, cycloheptane, cyclooctane and cyclopentane; long chain alkanes such as heptane, decane, hexane, octadecane and tridecane; and more complex mixtures of molecules such as turpentine. ...
Preferred reaction inert solvents include, but are not limited to, tetrahydrofuran (THF), diethyl ether, dimethylformamide (DMF), benzene, toluene, xylene, o-dichlorobenzene, nitrobenzene, dichloromethane, 1,2-dichloroethane, dimethoxyethane (DME), or mixtures thereof. This reaction may be carried out...
