Trihydroxymethylnitromethane
[performance characteristics] trihydroxymethylnitromethane is a white yellowish crystal, and its aqueous solution is a colorless yellowish transparent liquid. They can be used for disinfection, biological inhibitors of water circulatory system, raw materials of bradyrhionamide for medical use, and so on.
[quality indicator1] 50% liquid, density (20 ° C) 1.05-1.15 g / cm2, viscosity (20 ° C) < 20 MPa s. Purity 48-52%, pH 2-4.5, and free aldehydes < 1.0%.
[quality indicators2] solid, ≥ 97% pure, MP ≥ 170 ° C, moisture ≤ 1.0%.
[notes] this article is a colorless yellowish clear liquid, low toxicity, human body should not be in direct contact, storage at room temperature, such as the temperature is too low, may have colorless crystals appear.
Trihydroxymethylnitromethane
Trihydroxymethylnitromethane, a fungicide particularly suitable for industrial use to inhibit bacteria and eliminate silt, is marketed as a 50% water solution for sale.
Pure trihydroxymethyl nitromethane is white crystals, quite stable in the dry state, slowly decomposes at the melting point, and since its decomposition is endothermic, it does not develop into a self-sustaining reaction.
Trihydroxymethylnitromethane is highly soluble in water, and aqueous solutions are stable when neutral or acidic, however slowly decomposes to evolve formaldehyde in slightly basic solutions. The pH increased and the rate of evolved formaldehyde accelerated. The rate of formaldehyde release can be easily controlled with pH or temperature, so, the lifetime of trihydroxymethylnitromethane can vary from minutes to months depending on the conditions of use.
