    摘要： The invention relates to a pump (1) comprising a pump feed tube (13) for transporting a heat exchange medium (6) for a reactor containing a bundle of catalyst tubes (2). The pump (1) has a housing (14) that surrounds the pump feed tube (13) and comprises an opening (15) in the lower part of the housing (14), which allows the heat exchange medium (6) that is drawn from the lower section of the reactor by the pump (1) to flow into the housing (14). The medium flows upwards in the section lying between the internal wall of the housing (14) and the external wall of the pump feed tube (13), optionally over a heat exchanger (18) and into the interior of the pump feed tube (13) via an opening (16) in the upper section of said pump feed tube (13). The medium then flows through the pump feed tube from top to bottom, into the reactor via an opening (17) in the lower section of said tube (13) and into the upper section of the intermediate chamber between the catalyst tubes (2).

    摘要： The invention concerns binders containing: A) an aminotriazine derivative in which the triazine primary amino groups are methylolated on average with at least one mol of formaldehyde per mole of primary amino groups and these methylol groups are etherified on average with at least 0.5 mole primary alcohol per mole of methylol group, and the primary alcohols are a mixture containing: a) 0.5 to 99.5 mol % of a C1-C4 alkanol and b) 99.5 to 0.5 mol % of an alcohol of the formula (I) R?1-O-[R2-O]¿n-R3-OH, in which R1 stands for a C¿1?-C24 alkyl group or a C6-C12 aryl group which may optionally be substituted by one to three C1-C8 alkyl groups, and R?2 and R3¿, independently of each other, stand for a C¿2?-C8 alkylene group, and n means an integer from 1 to 100, or a mixture of higher-boiling alcohols having a boiling point of more than 120 °C at 1 bar, which contains at least 10 mol %, relative to the higher-boiling alcohols, of alcohols of formula I; and B) a radical polymer, which can be crosslinked with the aminotriazine derivative, a polycondensate or polymer additive.

    摘要： The invention relates to a method for producing phthalic anhydride that conforms to specifications in a purification of crude phthalic anhydride by distillation at a reduced pressure. According to said method, the crude phthalic anhydride is supplied to the distillation column above a lateral outlet, the low-boilers are drawn off at the head of the column or in the vicinity of the head of the column and the phthalic anhydride that conforms to specifications is removed from the lateral outlet. The method uses a distillation column with a number of theoretical separation stages situated above the supply of the crude phthalic anhydride to the distillation column that lies between 10 and 20 and the column operates with a reflux ratio of between 0.1 and 0.5.

    摘要： The invention relates to a reactor for testing a catalyst system, comprising a plurality of parallel contact tubes (2) which are arranged in the inner chamber of the reactor, the ends of said contact tubes being welded to tube bottoms. Said reactor also comprises hoods (3) at the two ends thereof, said hoods respectively defining a hood space (4). A liquid reaction medium (5) is supplied to the contact tubes (2) via a hood space (4), flowing through the contact tubes (2) and being transported away via the other hood space (4). The reactor also comprises a heat exchanging agent circuit with the heat exchanging agent (6) supply at one end of the reactor, the throughflow of the intermediate area between the contact tubes (2), and the discharge at the other of the reactor, the contact tubes (2) being arranged in at least two contact tube regions which are thermally separated from each other.

    摘要： The invention relates to an aqueous resin composition, comprising, in addition to water, a resin content in the range of from 65 to 80 % by weight, based on the aqueous resin composition. The resin is obtainable from melamine and formaldehyde and optionally at least one additive, and the aqueous resin composition has a viscosity ranging from 100 to 3000 mPas at 20 °C. The invention further relates to a method for producing the resin composition, to a composite containing said composition, to an impregnating resin dispersion, and to a method for producing the same. The invention also relates to the storage and use of said resin composition and impregnating resin dispersion.
