    摘要: A process for producing secondary amines of the formula R1R2N—A—NH—A—NR1R2, where R1 and R2 are linear or branched C1-20-alkyl radicals, optionally substituted with from 1 to 5 phenyl groups; or cyclohexyl radicals; or together with the nitrogen atom to which they are bound, form a 3 to 7 membered saturated ring, optionally containing further hetero atoms selected from the group consisting of N, O and S, and optionally substituted with from 1 to 5 C1-2-alkyl groups. The group A is a linear or branched C2-20-alkylene group, optionally containing from 1 to 5 phenylene groups; or a radical of the formula —CH(R3)—[CH2]k—X—[CH(R3)—[CH2]k—X]m—CH(R3)—[CH2]k—, where R3 is H or CH3, X is O, S or NR4, R4 is H or a linear or branched C1-4-alkyl group, k is 1 or 2, and m is an integer from 0 to 4; or a group of the formula where n, o, p, and q are, independently, integers from 1 to 4. In this process, primary amines of the formula R1R2N—A—NH2 are reacted in the presence of hydrogen and a catalyst comprising at least one element or compound of an element of groups VIII and IB of the Periodic Table, preferably group IB, and in particular, Cu. Through this process, a high selectivity of the desired amines can be achieved.

    摘要: Double closing unit of an injection molding machine has a pair of movable mold mounting plates and a stationary mold mounting plate having a pair of stationary mold faces, aligned between the pair of movable mold mounting plates. Two pairs of bar members and a pair of locking units are provided so that each locking unit couples one of the pair of movable mold mounting plates to one of the pairs of bar members. A pair of pressure cushion systems located in the stationary mold mounting plate are each connected to one of the pair of movable mold mounting plates, the pair of pressure cushion systems being independent of each other. At least one pair of fast-motion cylinders is also provided, at least one cylinder being connected between each movable mold mounting plate and the stationary mold mounting plate. The cylinders hold one of the movable mold mounting plates in a closed position when the other movable mold mounting plate is in an open position.
