摘要： A safety cabinet has a plurality of walls defining a front open side and a pair of doors pivotal about respective horizontally spaced axes on the walls between a closed and an open position. Guides in the cabinet are each associated with a respective one of the doors, and respective links each have a front end connected to a respective one of the doors and a rear end shiftable front-to-back in a respective one of the guides. A connector extends between the rear ends of the links and shifts front-to-back with them. A closer is operatively engageable with the connector, and a spring applies bears on the closer to urge it against the connector for pushing same into the rear end position and closing the doors. An actuator normally holds the closer out of engagement with the connector during movement of same between the front and rear end positions.

摘要： The invention relates to a method for treating vapours and condensates which arise during the production of polycondensates from bisphenols or high-value phenols by esterification and/or transesterification with alkyl or aryl esters of at least bivalent organic or inorganic acids. According to the invention, the treatment is carried out in a plurality of condensates and/or distillation columns which are connected in a step-by-step manner behind each other, each distillation column comprising a connected condensate. The dew point and the pressure in each condensate are adjusted such that in each step, monomers, oligomers or decomposition and transformation products are removed.

摘要： Disclosed are a method and a device for batchwise production of high-molecular polyphosphonates, polysulfones, polyarylates, polyamides, polyarylene ethers, or polyether ketones by melt-condensing a monomer compound carrying hydroxyl groups, carboxyl groups, anhydride groups, phosphoric acid groups, phosphono groups, phosphonate groups, phosphino groups, phosphinate groups, carbonyl groups, sulfonyl groups, sulfonate groups, siloxane groups or amino groups on its own or along with at least one diphenol, dialcohol, diamine, or a dicarbonate component. According to the invention, a) esterification or reesterification and precondensation are performed in a batchwise operated first reactor (1) in the presence of an esterification catalyst or reesterification catalyst; b) polycondensation is then optionally performed in a batchwise operated intermediate reactor (6) by optionally adding one or several additional monomers, another catalyst, and additives until a predetermined polycondensation level or viscosity level has been attained; and finally (c) condensation is continued in a batchwise operated final reactor (12) until the desired polycondensation level or viscosity level has been reached; and d) branching molecules comprising more than two functional groups are optionally added prior to or during esterification or reesterification, prior to or during polycondensation optionally performed in the intermediate reactor, or prior to or during polycondensation performed in the final reactor. The dwell time in the reactors ranges between 5 minutes and 15 hours while the temperature is set to 180 to 300° C. in reactors (1) and (6) and to 240 to 400° C. in reactor (12), the pressure being continuously or gradually lowered from 2000 to 100 mbar in reactors (1) and (6) and to 100 to 0.01 mbar in reactor (12) by sucking off the vapors produced during condensation.

摘要： A process for continuous or discontinuous synthesis of elastomeric copolyesters from polybutylene terephthalate (PBT) and polyoxytetramethylene glycol is described in which the tetrahydrofuran (THF) obtained as a byproduct in synthesis of polybutylene terephthalate from 1,4-butanediol is rectified and then reacted by ring-opening polymerization to form polyoxytetramethylene glycol which condenses with the free or esterified carboxyl groups of PBT to form the copolyester, whereby chain termination and catalyst deactivation are accomplished by adding 1,4-butanediol without separating the catalyst.

摘要： The invention relates to a method, which is used to monitor the composition of a polymer blend, melt and/or solution used to produce a polymer and to an automatic analysis device (27). To produce the polymer, the polymer blend, melt and/or solution is guided through an installation volume and a sample gas that is formed from said polymer blend, melt and/or solution is withdrawn, preferably at several sampling sites (30 to 36). The sample gas is fed to a mass spectrometer (28), which automatically emits an analysis signal representing the composition of the sample gas. The sampling site is connected to the mass spectrometer in a switchable manner via an automatically switchable shut-off device (47, 48), in such a way that several sampling sites can be sampled in succession by the mass spectrometer (28). The use of the mass spectrometer (28) permits an extremely accurate analysis of the composition of the sample gas and precise control of the process parameters of the reactor systems that are used for the polymer production. Said method and automatic analysis device can be used, in particular, during a polycondensation process.
