    Abstract: A process for preparing xylylenediamine by continuously hydrogenating liquid phthalonitrile over a heterogeneous catalyst in the presence of liquid ammonia in a reactor, which comprises mixing a stream of a phthalonitrile melt in liquid form by means of a mixer unit with a stream of liquid ammonia and conducting the liquid mixture into the hydrogenation reactor.

    Abstract: The invention relates to a method for the production of diaminoxylene, by continuous hydrogenation of liquid phthalonitrile, on a heterogeneous catalyst, in the presence of liquid ammonia, in a reactor, whereby a part of the reactor product is continuously recycled to the reactor feed as a liquid recycle stream (recirculating loop). A flow of fused phthalonitrile is added as a liquid to the recycle stream around the hydrogenation reactor in a mixing device, whereby the phthalonitrile conversion in the reactor on a single pass is greater than 99 % and the recycle stream comprises more than 93 % by weight of liquid ammonia and diaminoxylene and contains no further solvent for phthalonitrile.

    Abstract: Preparation of beta -aminopropionic acid derivatives by reacting primary/secondary amine with an acrylic acid derivative, comprises reacting first primary or secondary amine with acrylic acid derivative to obtain a first beta -aminopropionic acid derivative and unreacted acrylic acid derivative; and completely reacting the unreacted acrylic acid derivative with a second secondary amine to obtain a second beta -aminopropionic acid derivative, where the reaction mixture contains beta -aminopropionic acid derivative and unreacted secondary amine. Preparation of beta -aminopropionic acid derivatives by reacting a primary/ secondary amine with an acrylic acid derivative, comprises reacting first primary or secondary amine as value amine with acrylic acid derivative to obtain reaction mixture containing a first beta -aminopropionic acid derivative as an end product in addition with unreacted acrylic acid derivative, where the amount of the acrylic acid derivative is large, when compared with the value amine; and completely reacting the unreacted acrylic acid derivative with a second secondary amine as a trapping amine to obtain a second beta -aminopropionic acid derivative, where the reaction mixture contains first beta -aminoproionic acid derivative as end product, second beta -aminopropionic acid derivative and unreacted secondary amine.
