摘要:A method for treating a shear-thinning residue composition deriving from the synthesis of an aryl ether ketone, the residue composition including a liquid fraction and solid residues, the method including the steps of: passing said shear-thinning residue composition through a shear-generating evaporating device, between a rotating part and a stationary part; and recovering a condensed liquid fraction and separately recover concentrated solid residues.

摘要:The invention on hand refers to diseases associated with abnormal protein structures, including Alzheimer's disease, Creutzfeldt-Jakob's disease, BSE and other prion-associated diseases. It is the task of the invention on hand to provide new active agents preventing the formation of amyloid plaques and to dissolve existing plaques, such agents being convenient for therapy, diagnosis and prophylaxis of diseases that are associated with abnormal protein structures. This task is performed in terms of the current invention by heterocyclic or aromatic agents with a rigid structure and a donor-acceptor-donor pattern (DAD), the latter being formed by donors and acceptors of hydrogen bridge linkages which comply with the β-sheet structure of the peptide or protein and thus fit as binding partners. The heterocyclic or aromatic agents are available at least as dimers. They recognise peptides and proteins with a β-sheet structure, form stable complexes with them and inhibit their aggregation to β-amyloid plaques. Furthermore, the new active agents are able to dissolve β-amyloid plaques that already exist. Another task of the current invention is to provide methods for the synthesis of said heterocyclic or aromatic compounds.

标题:Process for the manufacture of 1,4-bis(4-phenoxybenzoyl)benzene with a zeolite catalyst

摘要:1,4-Bis(4-phenoxybenzoyl)benzene is made in a heterogeneous system by a reaction of diphenyl ether with 1,4-benzenedicarbonyl chloride at 190°-250° C. in the presence of a zeolite catalyst having a ring structure containing 12 oxygen atoms, which can be either an activated zeolite in hydrogen form or an iron-exchanged zeolite, which zeolite can be readily separated from the hot liquid phase in the reaction mixture. The mole ratio of diphenyl ether to 1,4-dicarbonyl chloride, when the catalyst is in hydrogen form, is about 50-80:1; when the catalyst is in iron-exhcanged form, it is about 10-50:1, and the weight ratio of 1,4-benzenedicarbonyl chloride to zeolite in hydrogen form is 3:1 to 1:2, while the ratio of 1,4-benzenedicarbonyl chloride to zeolite in iron-exchanged form is 10:1 to 1:32. The product readily crystallizes in a high state of purity from the cooled solution. 1,4-Bis(4-phenoxybenzoyl)benzene is a vaulable intermediate in the synthesis of polyetherketone resins.

标 题:Dispersant for use in synthesis of polyaryletherketones
发明人：NAIR KAMLESH P
权利人:TICONA LLC
摘要:A method for forming a polyaryletherketone is described. More particularly, a reaction mixture is initially supplied to the reactor vessel that contains one or more precursor monomers. A heteroaryl compound is also added to the reaction mixture. The reaction can be carried out according to, e.g., an electrophilic aromatic substitution reaction or a nucleophilic aromatic substitution reaction. The heteroaryl compound can serve as a dispersant to the polymer as it is formed. This minimizes the likelihood of gelling of the product polymer within the reactor vessel and limits the impact of process disruptions on the production of the polyaryletherketone.
