Trioctylphosphine oxide

Description:

Trioctylphosphine oxide (TOPO) is an organophosphorus compound characterized by its chemical formula C24H51O and a molecular weight of approximately 366.6 g/mol. It appears as a colorless to pale yellow liquid and is known for its high viscosity and solubility in organic solvents, such as toluene and chloroform, while being insoluble in water. TOPO is primarily used as a ligand in coordination chemistry and as a surfactant in various applications, including the synthesis of nanoparticles and in the extraction of metals. Its structure features a phosphine oxide functional group, which imparts unique chemical properties, such as the ability to form stable complexes with metal ions. Additionally, TOPO exhibits thermal stability and can withstand elevated temperatures, making it suitable for high-temperature processes. Safety considerations include handling it with care, as it may cause irritation upon contact with skin or eyes. Overall, TOPO is a versatile compound with significant applications in materials science and chemical synthesis.

Tri-n-octylphosphine oxide

CAS: 78-50-2

Tri-n-octylphosphine oxide (TOPO) is a chemical compound that is used in the treatment of wastewater. It is a white solid that has a melting point of 102 °C and an odor threshold of 0.05 ppm. TOPO reacts with citric acid to form sodium citrate, which is soluble in water. Sodium carbonate is formed when TOPO reacts with sodium hydroxide. This chemical also has synergistic effects with other chemicals, such as aluminum sulfate and ferric chloride, which are used for wastewater treatment. TOPO can be used to remove organic compounds from wastewater by oxidation reactions, such as methyl ethyl alcohols or methyl ethyl acetates. The reaction solution changes color from yellow to red during the oxidation process, which indicates the removal of these compounds from the solution. The reaction between TOPO and hydrogen peroxide produces heat and oxygen gas, which can be measured using calorimetry or spectrometry techniques.br>br
