Abstract: The present invention relates to compositions containing at least 80% by weight, especially at least 90% by weight, based on the total weight of the composition, of at least one magnesium sulfate-urea compound selected from the compound of the formula (I) and mixtures of the compound of the formula (I) with the compound of the formula (II): [MgSO4.mCO(NH2)2.nH2O] (I), [MgSO4.xCO(NH2)2.yH2O] (II), in which m and x are each in the range from 0.9 to 1.1, n is in the range from 1.9 to 2.1 and y is in the range from 2.9 to 3.1, where the compositions, based on the total weight of the composition, contain less than 10% by weight of free MgSO4 in the form of the anhydrate or in the form of hydrates of magnesium sulfate and less than 10% by weight of unbound urea. The invention also relates to the production of the compositions and to the use thereof as fertilizers or fertilizer additive.

Abstract: The subject of the invention is a composition containing at least 80 wt. %, with reference to the total weight of the composition, of a magnesium-sulfate-urea compound of Formula (I): [MgSO4.m CO(NH2)2.n H2O]??(I), in which m is in the range from 0.9 to 1.1 and n is in the range from 2.1 to 3.1, where the composition, with reference to the total weight of the composition, contains less than 10 wt. % free MgSO4 in the form of the anhydrate or in the form of urea-free hydrates of the magnesium sulfate, such as magnesium sulfate or magnesium-sulfate hexahydrate and/or less than 10 wt. % uncombined urea. In particular, m in Formula (I) indicates the value 1. In particular, n in Formula (I) indicates the value 3. The invention also concerns the manufacture of the compositions and their utilization as fertilizers or fertilizer additives.

Abstract: The present invention relates to compositions obtainable by reaction of a hydrate of magnesium sulfate with diammonium hydrogenphosphate and a further inorganic substance, especially anhydrous magnesium sulfate. The invention also relates to the production of the compositions and to the use thereof as flame retardants.

Abstract: A process is for the production of potash fertilizer granulates which have a stable shelf life also at high relative air humidities. This granulate contains an additive in the form of magnesium oxide and/or calcium oxide in a fine powder form, which is added by metering in prior to the compacting step. The result is a high final bursting strength even if the granulate is stored in a wet climate.

Abstract: Plastic mixtures, in particular those of a similar density such as polyethylene and polypropylene, are separated electrostatically, whereby prior to charging, the mixture is subjected to a surface treatment.

Abstract: Plastic mixtures, in particular those of a smilar density such as polyethylene terephthalate and polyvinyl chloride, are separated electrostatically, whereby the mixture, for triboelectric charging, is subjected to a thermal treatment.

Abstract: Plastic mixtures are split up into the individual components by a process combining density separation with electrostatic separation, and includes a special surface treatment which takes place prior to the electrostatic separation.
