摘要:Process for the preparation of a fluorinated sulphonic acid compound by hydrolysis of a corresponding fluorinated sulphonyl fluoride in the presence of a tertiary amine, comprising steps of n (a) recovering a mixture of a salt of the fluorinated sulphonic acid with the tertiary amine and an ammonium fluoride salt of the tertiary amine; n (b) distilling off the tertiary ammonium fluoride salt and leaving a distillation remanence containing the salt of the fluorinated sulphonic acid with the tertiary amine; and n (c) recovering the fluorinated sulphonic acid compound from the distillation remanence.

摘要:A chemical synthesis process is provided for the functionalization of monodispersed triblock copolymer (POEw-POPy-POEw) with secondary or tertiary amines at a semi-industrial level in glass reactors having a capacity between 1 L and 100 L. The process includes two stages where the first stage uses an alkylsulfonyl or arylsulfonyl chloride to obtain better leaving groups, and the second stage is the nucleophilic substitution with secondary or tertiary amines, to obtain the bifunctionalized triblock copolymers. The main advantage for this process is to reduce the quantity of unitary process done in each stage, the optimization of reaction times, and the stoichiometric relationships.

标 题:Ligated polyoxometalates and methods for their synthesis
发明人：MAZANY ANTHONY M
权利人:GOODRICH CO B F
摘要:Polyoxometalates are provided which are highly soluble in organic solvents, including monomer mixtures utilized in reaction injection molding. High solubility is obtained by organic moieties incorporated in the cation and anion of compounds having the formula [R1mER2m']nMxOyLz. These compounds provide improved solubility while maintaining catalyst activity within reaction injection molding formulations. A method is also provided for preparing these polyoxometalates within an aqueous acidic medium, wherein ligands are incorporated in the complex simultaneously with the formation of the polyoxometalate complex.
