摘要:
A process for the manufacture of a haloaryl compound which comprises contacting a mixture of dihalodiarylsulfone isomers [mixture (M)] with sulfuric acid to provide a mixture of haloarylsulfonic acid isomers [mixture (M1)] and reacting mixture (M1) in the presence of water. The process is independent on the manufacturing process of mixture (M) and is advantageous in that the obtained haloaryl compound can be recycled to the first step of a dihalodiarylsulfone manufacturing process.

摘要:
A separation medium consisting of a cyclodextrin metal-organic framework (CD- MOF) for separating aromatic compounds and methods of preparing the same are presented. The method includes one of the following procedures. A bottom-up preparation includes the following steps: (a) preparing a first mixture comprising a cyclodextrin, an alkali metal salt, water and an alcohol; (b) performing one of the following two steps: (i) stirring the first mixture; or (ii) adding an amount of a surfactant to the first mixture to form a second mixture; and (c) crystallizing the CD-MOF from the first mixture or the second mixture. A top-down preparation includes the following steps: (a) preparing a first mixture comprising the cyclodextrin, an alkali metal salt, water and an alcohol; (b) crystallizing the CD-MOF from the first mixture; and (c) optionally performing particle size reduction of the crystallized CD-MOF. The CD-MOFs are amenable for use in methods for separating alkylaromatic compounds and haloaromatic compounds from a mixture of hydrocarbons.
