摘要： The invention relates to a process for preparing N-phosphono-methylglycine by reacting a hexahydrotriazine compound with a triacyl phosphite in an organic solvent, hydrolyzing the resulting phosphono compound after prior extraction into an aqueous phase and separation from the organic phase. The process avoids decomposition of the organic solvent during hydrolysis.

摘要： Production of alkylaromatic compounds (I), by reacting 3-30C olefins (II) (or alcohols forming (II) under the reaction conditions) with aromatic hydrocarbons (III) in presence of an alkylation catalyst (IV), is carried out in a cascade of at least two reactors each containing (IV), where at least 80 % of (III) is supplied to the first reactor of the cascade and at least 40 % of (II) is supplied after the first reactor. An independent claim is included for the preparation of alkylarylsulfonates (A), by: (1) converting a 4C olefin mixture over a metathesis catalyst to give an olefin mixture containing 2-pentene and/or 2-hexene; (2) catalytically dimerizing the 2-pentene and/or 2-hexene (optionally after isolation) to give a mixture containing 10-12C olefins, optionally separating the 10-12C olefins and separating 5-30 wt. % (based on the 10-12C olefins) of low-boiling components of the 10-12C olefins; (3) reacting the obtained 10-12C olefin mixture with (III) in presence of (IV) to give alkylaromatic compounds (I'), optionally with addition of 0-60 wt. % (based on the 10-12C olefin mixture) of linear olefins before the reaction; (4) sulfonating (I') and neutralizing to give (A), optionally with addition of 0-60 wt. % (based on (I')) of linear alkylbenzenes (provided that no mixing has been carried out in the previous step); and (5) optionally mixing the obtained (A) with optionally with addition of 0-60 wt. % (based on (A)) of linear aralkylsulfonates (provided that no mixing has been carried out either of the previous two steps); The novel feature being that the reaction in the alkylation stage (3) is carried out as for the present procedure for preparing (I).

摘要： The invention relates to a method for producing polyamides, their oligomers or mixtures thereof, optionally containing other reaction products, by reacting aminonitriles or dinitriles and diamines or a mixture containing aminonitril e, dinitrile and diamine and optionally additional polyamide-forming monomers and/or oligomers with water in a reactor (1) with a vertical longitudinal axis. According to said method, the reaction product is exfiltrated from the sump in the reactor (1) and accumulated ammonia and optionally other accumulated low-molecular compounds and water are drawn off via the head (2) . The invention is characterised in that the reactor (1) comprises at least tw o chambers (4) arranged in a longitudinal direction one above the other, that the chambers (4) are separated from one another by liquid-tight floors (5), that each chamber (4) is connected to the one (4) immediately below by a respective liquid overflow (6) and a liquid product stream is drawn off via the liquid overflow (6) of the lowest chamber (4), that the gas chamber (7) above the liquid level in each chamber (4) is connected to the respective chamber (4) lying immediately above it via one or several conduits (8), whic h open respectively into a gas diffuser (9) comprising orifices (11) for the discharge of gas below the liquid level. The reactor also comprises at least one respective deflector plate (12) positioned vertically around each gas diffuser (9), the upper end of said plate terminating below the liquid level and the lower end terminating above the liquid-tight floor (5) of the chambe r (4), thus sub-dividing each chamber (4) into one or more compartments suppli ed with gas (13) and one or more compartments without gas (14).
