    摘要: A computer-implemented method for providing at least one migration risk index, comprising the steps: providing soil data for a location, comprising at least information on the soil composition at that location (S10); providing weather data for said location, comprising at least historical precipitation data for said location (S20); providing a soil mobility model for a product, wherein the soil mobility model is configured to calculate migration data of the product at said location depending on the soil data and the weather data (S30); and determining at least one migration risk index based on the migration data and being representative of a risk that said product migrates down to a lower soil layer at said location (S40).

    摘要: The invention relates to a process for producing isocyanates by reacting the corresponding amines with phosgene in the liquid phase, comprising: (a) mixing an amine comprising feed stream, a phosgene comprising feed stream and optionally an inert solvent; (b) reacting the amine with phosgene in a first reaction section to obtain an intermediate reaction mixture comprising isocyanate, carbamoyl chlorides, amine hydrochlorides and unreacted phosgene; (c) cleaving the carbamoyl chlorides and remove phosgene from the intermediate reaction mixture in a second reaction section to obtain an isocyanate comprising crude product, (d) optionally working-up the crude product; wherein reacting (b) is carried out such that the intermediate reaction mixture comprises 1.7 to 5 mol-% solid amine hydrochlorides based on the molar amount of amine fed into the process.
