Abstract: This conversion procedure is initiated mixing of water solutions related to ammonium sulphate and potassium chloride in a molar ration of pure salts 1 up to 1,25 : 2, after that a molar ration of water related to molar ratio of incoming salts 7,5 up to 5,0 : 1 is provided, which is aimed based on this principle a partial amount of water is being evaporated and a hot suspension is being cooled to the temperature of +45 up to +20 Celsius degrees after that, and the pH value corrected, when supplying ammonium so that, the pH value in the interval of 7 up to 12 is reached, however the suitable value is 10, and a separation of crystal of the such prepared suspension is provided, while the separated crystalline prepared based on this suspension is being washed with the use of water. The prepared crystalline of potassium sulphate containing less than 1,5 weight percent of chlorides and 0,6 up to 3 weight percent of 0,6 up to 3 weight percent ammonium nitrogen is applied as potassium manure.

Abstract: This patent describes a procedure closed to neutralisation of lactam-sulphuric acid and processing of neutralisation product which is based on this principle, that 1 weight part of lactam - sulphuric acid is mixed with 2 up to 10 weight parts of water solution closed ammonium sulphate or sulphate of several alkaline metals, the pH value is corrected so that, it is in the interval of 0,6 up to 2,5 with the use of added ammonium or alkaline metal carbonate, alkaline metal hydroxide or oxide or their mixture, and this mixture is processed with the use of toluene or trichlorethylene.

Abstract: This patent describes the procedure of the production based on the intermediate product closed to caprolactam of the lactam sulphuric acid and ammonium. Lactam sulphuric acid is supplied to the mixed suspension created based on the crystal of ammonium sulphate, the water solution of it and the water solution of caprolactam. This suspension is kept at the temperature of + 25 up to 60 Celsius degrees based on the cooling and the pH value in the interval of 4,0 up to 6,5 is kept based on the ammonium supplied to this mixture, while caprolactam solution and crystalline ammonium sulphate is created as a result of this reaction, which is led to the sedimentation in a counterflow of flowing distilled water, being alkalised based on ammonium to pH value of 8 up to 14, dosed in a quantity being able to dissolve 10 up to 60 percent of the mass closed to the created crystal of ammonium sulphate, which is being separated of this processing a ammonium sulphate crystal having a chemical purity.

Abstract: Solution is dealing with the process of continual separation of acetonoxim in the mixture with aqueous solution of ammonium sulfate and acetone. Separation is processed in packing column where is from the side of the column sprayed the mixture of acetonoxim, aqueous solution of ammonium sulfate and acetone. From the head of column is yielded isotropic mixture acetonoxim, water and acetone and from the bottom of the column through the heater is flowing the mixture of ammonium sulfate. Steams with the content to 0,11 molar fraction of acetonoxim are anorganic component free. Acetonoxim separated by this method is usable at the preparation of hydroxylamin salts eventually after condensation as aqueous solution in organic synthesis.
