摘要:The present invention refers to a method for the synthesis of an adsorbing material consisting of a single-phase tetravalent manganese feroxyhite (Å?-Fe (1-x) Mn x OOH), in which a percentage of 0.05 to 25% of iron atoms has been isomorphically substituted by Mn(IV) atoms. Its production takes place in a continuous two-stage flow reactor at weakly acidic conditions (pH 4-7) and high redox (300-800 mV). The material can be used for the removal of both pentavalent and trivalent arsenic as well as other heavy metals form water. More specifically, its adsorption capacity and selectivity depending on the trivalent and pentavalent arsenic water content, are determined by the manganese percentage and the compact or hollow morphology of its structural unit which can be both controlled by the parameters of the synthesis procedure.

标题:Process for the synthesis of 2-hydroxyphenyl alkyl ketones

摘要:A process is described for the synthesis of 2-hydroxyphenylalkyl ketones, by means of catalytic rearrangement of phenolic esters. This process is characterized by the use, as catalysts, of crystalline aluminosilicates of the pentasyl type having predefined values of silica/alumina ratio, grain size, surface area and porosity, and containing between 10 wt% and 40 wt% of finely ground alumina as bonding agent. The rearrangement thus catalyzed involves a high conversion of the phenolic ester, a high orthoselectivity and a low formation of phenolic by-products, thus enabling the formation of the end product in high yields. In particular, the process applies to the synthesis of 2-hydroxyacetophenone.

摘要:The invention relates to the process of preparation of 2-fluoro-4-(3-methoxyphenyl)aniline (3) as an intermediate. Said intermediate 2-fluoro-4-(3-methoxyphenyl)aniline (3) is obtained in a Suzuki coupling reaction from (3-methoxyphenyl)boronic acid (1) and 4-bromo-2-fluoro-aniline (2). The invention further relates to the synthesis of vidofludimus (5) from said intermediate 2-fluoro-4-(3-methoxy-phenyl)aniline (3) and from 1-cyclopentene-1,2-dicarboxylic anhydride (4). The invention further relates to the synthesis of vidofludimus calcium (6) from said vidofludimus (5) and from a calcium salt, preferably Ca(OH)2.
