11358133 · 2022-06-14 · ·

Metal ion-directed carboxylic acid functionalized polyoxometalate hybrid compounds, and their preparation method and applications in catalyzing the degradation of chemical warfare agent simulants. In the synthesis, Na.sub.2MoO.sub.4, p-hydroxybenzonic acid (PHBA), alanine (Ala), KCl, transition metal cations and As.sub.2O.sub.3 as raw materials and water are used as solvent. At room temperature, 2-chloroethyl ethyl sulfide (CEES) and the prepared polyoxometalate hybrid compounds were mixed together in anhydrous ethanol and stirred, and H.sub.2O.sub.2 was subsequently added into the reaction system. The catalytic reaction for the degradation of CEES was finished within 5 min under stirring. In the catalytic hydrolysis of diethyl cyanophosphonate (DECP), the catalyst, DECP, DMF and H.sub.2O were put together and mixed fully. The prepared polyoxometalate hybrid compounds have the advantages of high conversion, high selectivity and easy recyclability in catalyzing the degradation of two types of chemical warfare agent simulant.

Method for preparing chemical digester and its use for the treatment of organic matter

This invention refers to a method for preparing a chemical digester characterized by using organic and inorganic elements used for multiple purposes such as an accelerator in the decomposition of organic matter, as a water flocculant, as an organic soil fertilizer and as a means to eliminate the concentration of flies and other inserts in organic matter to decompose. The method comprises heating water in a reactor at a temperature of 38° C., adding a polysaccharide, an anti-thickener and an antifoam. The method then comprises the addition of two organic acids, one of them previously mixed in a second reactor and, finally, an inorganic acid until the mixture is homogenized. Optionally the method comprises the packaging of the mixture and the treatment of organic matter.
