    Abstract: The invention relates to a method for producing pure xylylenediamine (XDA) by continuous distillation of crude xylylenediamine (XDA) in a column, by using a side stream distillation column, the XDA being drawn off through the lateral discharge and the bottom product of the distillation column being further concentrated in an additional concentration step. The condensate obtained in the concentration step is returned to the side draw distillation column.

    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: COS is selectively removed with respect to CO2 from a hydrocarbonaceous fluid stream which contains CO2 and COS. Examples of the fluid stream include a gas stream, for example natural gas, synthesis gas from heavy oil or heavy residues or refinery gas, or from liquid or liquefied hydrocarbons, for example LPG (Liquefied Petroleum Gas) or NGL (Natural Gas Liquids). The process is carried out by (1) intimately contacting the fluid stream in an absorption or extraction zone with a scrubbing liquor consisting of an aqueous amine solution containing from 1.5 to 5 mol/l of an aliphatic alkanolamine having of from 2 to 12 carbon atoms and from 0.8 to 1.7 mol/l of at least one activator selected from the group consisting of piperazine, methyl piperazine and morpholine, (2) removing the COS essentially completely from the fluid stream, and (3) separating the substantially COS-decontaminated fluid stream and the COS-loaded scrubbing liquor and discharging them from the absorption or extraction zone.

    Abstract: A process for purifying tert. phosphine oxides of formula (R )(R )(R )P = O (I) in which R , R and R = 1-12 C alkyl, 5-8 FC cycloalkyl, aryl, 7-20 C aralkyl or 7-20 C alkylaryl, comprises reacting the (I) or a (I)-contg. mixt., opt. in an inert solvent, with an (in)organic acid at 0-150 degrees C and subsequently reacting the resulting salt with water or an (in)organic base. Pref. reaction with the acid is pref. carried out in an inert solvent such as aromatic hydrocarbons, aliphatic hydrocarbons, cycloaliphatic hydrocarbons or aromatic nitriles. Suitable acids are eg mineral acids such as HCl, HClO4, H2SO4 or H3PO4, Lewis acids such as BF3 or AlCl3, or organic acids such as acetic acid, formic acid or oxalic acid. The ratio acid to impure (I) is pref. 0.3 : 1 to 20 : 1, esp. 0.7 : 1 to 2 : 1. After crystallisation, the salt is recovered eg by filtration or centrifuging. The free (I) is liberated by treating the salt eg with an (in)organic base, esp. an aq. soln. of a base such as NaOH, KOH, Na2CO3, NH3, triethylamine, etc. The (I) is recovered e.g. by extraction with an inert solvent in the usual way.
