The process comprises a chemical reaction in which chlorobenzene is reacted with an alcohol in the vapor phase to form phenol and the corresponding alkyl chloride. A catalyst is used to promote the reaction. Among the alcohols used are methyl alcohol and ethyl alcohol.John Stauffer...
Chlorobenzene is a colorless to clear, yellowish liquid with a sweet almond-like odor. Flash point 84°F. Practically insoluble in water and somewhat denser than water (9.2 lb / gal). Vapors heavier than air. It can be converted to phenol by reaction with sodium hydroxide under extreme condi...
Chlorobenzene is used in the manufacture of aniline, phenol, and chloronitrobenzene; as an intermediate in the manufacture of dyestuffs and manypesticides, as a solvent; and emulsifier. 3.4 Purification Methods The main impurities are likely to be chlorinated impurities originally present in the *benz...
To convert chlorobenzene to biphenyl, we can use the Wurtz reaction, which involves the coupling of aryl halides in the presence of sodium metal. Here’s a step-by-step breakdown of the process:Step 1: Identify the Reactants -
(NPCl2)3 (102) was also polymerized to the high molar mass polymers in solution. Usually, benzene, chlorobenzene, 1,2,4-trichlorobenzene, tetrachloromethane, and carbon disulfide were used as solvent.238,252,276,284–286 The lower viscosity of the reaction mixture allowed for the better contr...
Chlorobenzene once was used in the manufacture of certain pesticides, most notably DDT, by reaction with chloral (trichloroacetaldehyde), but this application has declined with the diminished use of DDT. At one time, chlorobenzene was the main precursor for the manufacture of phenol: C6H5Cl +...

摘要: The vapor phase alkylation of chlorobenzene was promoted by H-mordenite treated with chlorofluoromethane. Ortho alkylation was preferentially promoted in the catalytic reaction after process times of 1 h.关键词:alkylation chlorobenzene H-mordenite reaction process ...
reaction (3.3.1). However, there is a limited proportion of Cl atoms relative to H atoms in the molecule of chlorobenzene, and, as seen fromFig. 3.3.1, hydrogen and benzene are among the main pyrolysis products of this compound. The formation of benzene can be explained by the reaction:...
