    Abstract: The invention is directed to an improved, reliably performable process for preparing triallyl isocyanurate (TAIC) by Cu 2+ -catalysed rearrangement of triallyl cyanurate (TAC) at at least 90°C. According to the invention, TAC and, if required, also a Cu 2+ catalyst and solvent are fed continuously to a start reaction mixture after onset of the initially inhibited isomerization reaction, the isomerization is performed at from 90 to 160°C and an amount of reaction mixture equivalent to the amount of reactant is drawn off continuously and sent to the workup. Preference is given to effecting the isomerization in TAIC as the reaction medium.

    Abstract: The hydrophilic silica flow improver used with flowable particulate cyanuric chloride of flowability index ≤ 3 is a precipitated silica or a silica gel with an average agglomerate diameter of below 15 microns, as determined by a Coulter Counter An Independent claim is included for the production of cyanuric derivatives by substitution of 1, 2 or 3 Cl atoms in the claimed cyanuric chloride.

    Abstract: The emptying station for bulk-bags containing particulate material comprises a box with a funnel-shaped outlet (2, 3) at the bottom. The bag (10) is held on a lift device (16) and opened by three cutter blades (4a) forming a pyramid with a spike (4b) at its point. The novelty is that the lift carries a lock (14) for the box and a seal (7) closes the space between the bag and box below the holders (15) for the bag. An Independent claim is included for a method of emptying a bulk-bag using the station.

    Abstract: The device comprises a holding component (3) for the bulk bag and a container-shaped component which is upwardly open and centrally positioned beneath the holding component. The container-shaped device is formed as a double tube, having inner tube (20) and surrounding outer tube (7) with an outlet (8) at its lower edge and a raisable and lowerable closure ring (9) for closing the upper end of the ring gap formed by the two tubes. The emptying device has at least one grip component (21) movable forwards and backwards within the inner tube for holding firmly the outlet of the inner sack which can be drawn downwards by a tractive device operable from outside the double tube device.
