Description
Известны способы экстракции тумминовых кислот из каустобиолитов с помощью водиых растворов щелочей. При этом концентраци растворов гумминовых кислот не превышает даже при гор чей экстракции.Known methods of extraction of humic acids from caustobioliths using aqueous solutions of alkalis. At the same time, the concentration of solutions of humic acids does not exceed even with hot extraction.
Предлагаемый способ выделени гумминовых кислот из каустобиолитов основан на использовании водных растворов аминов жирного р да или аминоспиртов в качестве экстрагентов.The proposed method for the isolation of humic acids from caustobioliths is based on the use of aqueous solutions of fatty amines or amino alcohols as extractants.
Благодар высокой раствор ющей способности предлагаемых растворителей , экстракцию провод т без нагревани , при этом концентраци гуммиповых кислот В 2 раза выще, чем при экстракции 2Vo раствором щелочи после 4 час кип чени .Due to the high dissolving capacity of the proposed solvents, the extraction is carried out without heating, and the concentration of gum acids is 2 times higher than in the extraction of 2Vo with an alkali solution after 4 hours of boiling.
Гумминовые кислоты осаждают из растворов в виде кальциевых солей, а экстрагенты регенерируют.Humic acids are precipitated from solutions in the form of calcium salts, and the extractants are regenerated.
Предмет изобретени Subject invention
Способ выделени гумминовых кислот из твердых каустобиолитов экстракцией водными растворами оснований, отличающийс тем. что, с целью упрощени технологии, повышени выхода продукта и повыщени экономичности процесса, экстракцию ведут на холоду с использованием ъ качестве экстракта слабых растворов аминов жирного р да или аминоспиртов с последующим осаждением гумминовых кислот из экстракционного раствора в виде кильциевых солей.The method of isolation of humic acids from solid caustobioliths by extraction with aqueous solutions of bases, characterized in that. that, in order to simplify the technology, increase the yield of the product and increase the efficiency of the process, extraction is carried out in the cold using an extract of weak solutions of fatty amines or amino alcohols followed by precipitation of humic acids from the extraction solution in the form of kilocyclic salts.
