Method for the production of a nanocrystalline molybdenum mixed oxide

A method for producing a composite material which contains a support material and an ionic liquid, as well as a composite material and its use as synthetic catalyst.

Method for producing a composite material

A method for producing phthalic anhydride by catalytic gas-phase oxidation of o-xylene and/or naphthalene, carried out by means of a catalyst arrangement which has a first catalyst layer at the gas inlet side and at least one second catalyst layer after the first catalyst layer in the gas flow direction with different catalytic activity, wherein when the gas-phase oxidation is being carried out a lower maximum temperature is formed in the first catalyst layer than in the second catalyst layer. Furthermore, a method for producing the catalyst arrangement, as well as the catalyst arrangement itself.

Process for preparing nanocrystalline mixed metal oxides

The invention relates to a method for the production of monomer organic carbonates from a mixture of organic carbonates and carbamates which are obtained by reacting urea, substituted urea, a salt or ester of carbamide acid or one of the N-substituted derivatives thereof with a polyalkylene glycol, polyester-polyol or a polyether-polyol of general formula (I), wherein R represents a linear or branched alkylene group having 2-12 carbon atoms and n represents a number between 2 and 20, or with a completely or partially hydrolysed polyvinyl alcohol of general formula (II), wherein R' represents an alkyl group, an aryl group or an acyl group having 1-12 carbon atoms, p and q represent a number between 120, or with mixtures of said compounds in the presence of a catalyst facilitating the separation of ammonia and the ammonia becomes free or the amine is removed from the reaction mixture by means of a strip gas, whereby said mixture is reacted with an alcohol or a phenol whereby monomer carbonates are formed and polymer polyalcohols of formulae (I) or (II) are reformed. 

Method for the production of organic carbonates

The invention relates to a method for the production of monomer organic carbonates, wherein urea, substituted urea, a salt or an ester of carbamide acid or one of the N-substituted derivatives thereof is reacted in a first step in a polyalkylene glycol, a polyester-polyol or a polyether-polyol of general formula (I), wherein R represents a linear or branched alkylene group having 2-12 carbon atoms and n is a number between (2) and (20), or in a completely or partially hydrolysed polyvinyl alcohol of general formula (II) wherein R' represents an alkyl group, an aryl group or an acyl group having 1-12 carbon atoms, p and q are numbers between 1 and 20, or in mixtures of said compounds in the presence of a catalyst facilitating the separation of ammonia in order to form a mixture containing carbonates and carbamates, the ammonia becomes free or the amine is removed form the reaction mixture by means of a strip gas. In a second reaction step (transesterification), the mixture containing the carbonates and carbamates is reacted with a monomer alcohol or a phenol whereby monomer carbonates are formed and polymer polyalcohols of formulae (I) or (II) are reformed.HO&#x2014;ROH&#x2003;&#x2003;(I)
