    摘要： A process for the preparation of a N-)ortho-alkylphenyl)-imide of the formula ##STR1## in which R.sup.1 to R.sup.9 is defined in the specification which comprises reacting a cyclic anhydride of the formula ##STR2## wherein R.sup.6 to R.sup.9 are difined in the specification with an amine of the formula ##STR3## optionally in the presence of an acid catalyst and optionally in the presence of a solvent which is immiscible or only slightly miscible with water but can form an azeotrope with water, at a temperature between 100.degree. to 200.degree. C. under conditions so that the water formed during the reaction is removed from the reaction mixture without the addition of a polymerization inhibitor or a dipolar solvent. The final products are used as intermediates to prepare heat-stable plastics as well as intermediates to prepare pharmaceutical and agricultural chemicals.

    摘要： Dinitro-polyalkylbenzenes can be prepared by nitration of polyalkylbenzenes using HNO.sub.3 in the presence of H.sub.2 SO.sub.4 in such a manner that at least 50% of the H.sub.2 SO.sub.4 is present as reaction medium and HNO.sub.3 and the polyalkylbenzene and any remaining H.sub.2 SO.sub.4 are added simultaneously in such a manner that the added substances polyalkylbenzene and HNO.sub.3 are in the molar ratio of 1:2-10. H.sub.2 SO.sub.4 is used at a concentration from 81 to 96% by weight and HNO.sub.3 at a concentration from 95 to 100% by weight. For the work-up, the dinitro-polyalkylbenzenes are first freed from the majority of the acids and then treated with a highly dilute aqueous solution of a dispersant for separating off residual acid.

    摘要： Mononitrohalogenobenzenes can be prepared by mixing halogenobenzene, nitric acid, sulphuric acid and water intensively with one another, simultaneously or in succession in their total quantity, and by redispersing them at least twice in the case of continuous preparation, applying a mixing energy of 1-40 watts per liter of the overall reaction mixture, preferably 3-30 W/l, largely suppressing back-mixing in the continuous procedure, and observing adiabatic reaction conditions.

    摘要： Mononitrotoluenes can be prepared by intensively mixing together toluene, nitric acid, sulphuric acid and water, simultaneously or successively in their total amount, and, in the case of continuous preparation, redispersing the mixture at least twice, for which purpose a mixing energy of 1 to 40 watts per liter of the total reaction mixture, preferably 3 to 30 W/l, is employed per volume of the reactor, and, for the continuous procedure, the back mixing is substantially repressed. Adiabatic reaction conditions are maintained.
