Abstract: PROCESS FOR THE MANUFACTURE OF CHLORIDE-FREE HIGHSTRENGTH POTASSIUM AMMONIUM NITRATE PHOSPHATE FERTILISERS BY REACTION OF POTASSIUM CHLORIDE WITH LIQUID OR GASEOUS N2O4 AT A TEMPERATURE OF AT MOST 80*C. THE REACTION MEDIUM USED IS PHOSPHORIC ACID OR A MIXTURE OF PHOSPHORIC ACID AND NITRIC ACID. AFTER REMOVAL OF THE NITROSYL CHLORIDE FORMED AND NEUTRALISING THE RESULTING ACID/ POTASSIUM NITRATE SUSPENSION WITH AMMONIA THE MIXTURE IS SHAPED AND DRIED.

Abstract: The resistance of plants to environmental factors such drought is increased by treating the plants themselves, their seeds before sowing or the surrounding soil, before or after emergence of the plants, with compositions containing aliphatic epoxymonocarboxylic acids containing one to three epoxy groups and 6 to 22 carbon atoms or the salts, lower alkyl esters, lower polyhydroxyalkyl esters, amides, monoalkylamides and dialkylamides thereof as active ingredient.

Abstract translation: 通过在植物出现之前或之后，通过处理植物本身，播种前的种子或周围土壤，植物对环境因素的抵抗力增加，其中含有含有一至三个环氧基的脂族环氧单羧酸和6-22个 碳原子或其盐，低级烷基酯，低级多羟基烷基酯，酰胺，单烷基酰胺及其二烷基酰胺作为活性成分。

Abstract: Dinitrogen tetroxide is produced by a catalytic oxidation of ammonia with air at atmospheric pressure followed by oxidation of the resultant nitrogen oxides by 50 to 70 percent HNO3. This increases the concentration of NO2 and results in formation of dilute HNO3. The NO2 is cooled and condensed by compression to at least four atmospheres at temperatures not below 8* C. to produce dinitrogen tetroxide in liquid phase and nitrogen dioxide in vapor phase. The latter is reacted with an excess of oxygen in the presence of the dilute nitric acid in the preceding step to produce nitric acid of 50 to 70 percent concentration which may be recycled to the step wherein the nitric oxide is oxidized by nitric acid. By the present process, the use of expensive and difficult-to-operate nitric acid concentrators is avoided.
