12 Jun 1997TL;DR: In this article, a new selective process for producing high-purity potassium nitrate or potassium phosphate was proposed, which uses a liquid agricultural or fermentation byproduct, such as molasses, vinasse or potato thick juice as its potassium source and comprises the following unit operations: clarification, ion exchange, neutralization, concentration and crystallization.
Abstract: The present invention relates to a new selective process for producing high-purity potassium nitrate or potassium phosphate. The process uses a liquid agricultural or fermentation by-product, such as molasses, vinasse or potato thick juice as its potassium source and comprises the following unit operations: clarification, ion exchange, neutralization, concentration and crystallization. Importantly, the present invention also concerns a process for producing an ingredient for animal feed, said ingredient having a reduced potassium content.

TL;DR: In this article, an insecticide-fertilizer particulate agent is described and a preparation method for its use in a crop sowing period and can be used for preventing underground pests and diseases at the rootstocks of crops.
Abstract: The present invention discloses an insecticide-fertilizer particulate agent and a preparation method thereof. The insecticide-fertilizer particulate agent comprises an insecticide, a bactericide, a fertilizer and an auxiliary agent. The insecticide is composed of one or more components selected from diazinon, thiamethoxam, imidacloprid, clothianidin, chlopyrifos, phoxim, carbofuran and carbosulfan. The bactericide is composed of one or more components selected from azoxystrobin, pyraclostrobin, fludioxonil, metalaxyl, methylimidazole bacteria aniline, thifluzamide and mancozeb. The fertilizer is composed of one or more components selected from urea, ammonium sulfate, potassium sulfate, potassium chloride, monoammonium phosphate, diammonium phosphate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate, ammonium polyphosphate, potassium nitrate, zinc sulfate, manganese sulfate, magnesium sulfate, borax, boric acid, ferrous sulfate, copper sulfate, ammonium molybdate, ethylene diamine tetraacetic acid, calcium nitrate, potassium humate, organic matter, amino acid and soybean meal. The insecticide-fertilizer particulate agent is applied during the crop sowing period and can be used for preventing and controlling crop underground pests and diseases at the rootstocks of crops.

TL;DR: In this article, a cyclic metallesis reaction is used to prepare the initial raw reaction liquid with common saturation point with ammonium nitrate, potassium chloride and water, adidng fresh water and potassium chloride, separating solid potassium nitrate to obtain the first-stage mother liquid, heating, adding ammonium ionate, negative-pressure evaporation to separate solid ammonium chloride, returning the second-stage mixtures, and repeating said steps.
Abstract: A process for preparing potassium nitrate by metallesis reaction is a cyclic reaction procedure, and includes preparing the initial raw reaction liquid with common saturation point with ammonium nitrate, potassium chloride and water, adidng fresh water and potassium chloride, separating solid potassium nitrate to obtain the first-stage mother liquid, heating, adding ammonium nitrate, negative-pressure evaporation to separate solid ammonium chloride, returning the second-stage mother liquid back to the crystallizing procedure of potassium nitrate, and repeating said steps. Its advantages are low energy consumption, low requirement for purity of raw material, low cost and simple process.
