14265-44-2 Usage

Uses

Phosphate is an inorganic compounds. It is a essential nutrient, found in many organic compounds including nucleic acids and lipids. Abundance of it has also been seen to promote cyanobacterial proliferation. It also promotes the forming of bones in the form of minerals in the apatite family.

Definition

ChEBI: A phosphate ion that is the conjugate base of hydrogenphosphate.

Agricultural Uses

Phosphates derived out of orthophosphoric acid are called orthophosphates. The most common phosphates are calcium dihydrogen phosphate [Ca(H2PO4)4], or single superphosphate and diammonium hydrogen phosphate (NH4)2HPO4 or DAP.

Check Digit Verification of cas no

The CAS Registry Mumber 14265-44-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,6 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 14265-44:
(7*1)+(6*4)+(5*2)+(4*6)+(3*5)+(2*4)+(1*4)=92
92 % 10 = 2
So 14265-44-2 is a valid CAS Registry Number.

Active agents in heterogeneous photocatalysis: Atomic oxygen species vs. OH. radicals: Related quantum yields

Herrmann, Jean-Marie

, p. 2731 - 2750 (2001)

After a general survey of the fundamental characteristics of heterogeneous photocatalysis, the present article classifies the ensemble of reactions into three major categories: i) mild oxidations, ii) total oxidations, and iii) reactions involving hydrogen. Depending on the presence or absence of H2O, the active oxidizing species will be either a dissociated neutral oxygen species, denoted as O*, which is present in anhydrous systems and responsible for selective mild oxidation reactions, or an OH. radical, formed in the presence of H2O and responsible for totally degradative oxidation reactions. The existence of O* species is substantiated by photoconductivity measurements, oxygen-isotope exchange, and reactions in which oxygen-free NO is the oxidizing agent. The influence of the five main parameters that govern kinetics experiments i) the mass of the catalysts, ii) the wavelength, iii) the concentrations or partial pressures of reactants, iv) the temperature, and v) the radiant flux is examined to determine the best conditions for obtaining the optimum photocatalytic quantum yield (PQY), the definition of which is based on the quantum yield given in [1] for photochemistry.

Synthesis, characterization of a ternary Cu(II) Schiff base complex with degradation activity of organophosphorus pesticides

Li, Xin,Zhang, Dandan,Liu, Zihui,Xu, Ying,Wang, Dongfeng

, p. 280 - 289 (2018)

Organophosphorus pesticides are a class of the most important groups of insecticides and are widely applied to pest and plant diseases control in agriculture. The extensive application of organophosphorus pesticides can subsequently release organophosphorus pesticides into environment which may pose a seriously adverse impact to non-target organisms and humans. However, we could not ban organophosphorus pesticides at present as they are very efficient. Therefore, the new technique of degradation of organophosphorus pesticides must be studied. In this paper, a ternary copper Schiff base complex 2Cu(C14H8NO3Cl)(C12H8N2)·3CH3OH was synthesized and characterised by physico-chemical and spectroscopic methods. The degraded effects of 4 pesticides by the complex were investigated. The results showed that the degraded rates of every organophosphorus pesticide were increased. However, the effects of degradation were varied because of the different molecule structures of organophosphorus pesticides. Gas chromatography-mass spectrometry (GC–MS) and ion chromatography were used to analyze the degradation products by the complex, and then the catalytic mechanism of degradation was proposed. The study results suggest that the Schiff base copper complex, as a potent catalyzer, may find its applications in catalytic degradation area.

Mechanistic information from pressure acceleration of hydride formation via proton binding to a cobalt(I) macrocycle

Fujita, Etsuko,Wishart, James F.,Van Eldik, Rudi

, p. 1579 - 1583 (2002)

The effect of pressure on proton binding to the racemic isomer of the cobalt(I) macrocycle, CoL+ (L = 5,7,7,12.-14, 14-hexamethyl-1,4,8,11-tetraazacyclotetradeca-4,11-diene), has been studied for a series of proton donors using pulse radiolysis techniques. The second-order rate constants for the reaction of CoL+ with proton donors decrease with increasing pKa of the donor acid, consistent with a reaction occurring via proton transfer. Whereas the corresponding volumes of activation (ΔV?) are rather small and negative for all acids (proton donors) with pKa values below 8.5, significantly larger negative activation volumes are found for weaker acids (pKa> 9.5) containing OH groups as proton donors. In the latter case, the observed ΔV? for these protonation reactions show a correlation with the reaction volumes (ΔV°ion) for the ionization of the weak acids with a slope of 0.44, indicating that bond dissociation of the weak acid molecule bound to the metal center proceeds approximately halfway at the transition state along the reaction coordinate in terms of volume changes.

Geochemical Sources and Availability of Amidophosphates on the Early Earth

Gibard, Clémentine,Gorrell, Ian B.,Jiménez, Eddy I.,Kee, Terence P.,Pasek, Matthew A.,Krishnamurthy, Ramanarayanan

supporting information, p. 8151 - 8155 (2019/05/16)

Phosphorylation of (pre)biotically relevant molecules in aqueous medium has recently been demonstrated using water-soluble diamidophosphate (DAP). Questions arise relating to the prebiotic availability of DAP and other amidophosphosphorus species on the early earth. Herein, we demonstrate that DAP and other amino-derivatives of phosphates/phosphite are generated when Fe3P (proxy for mineral schreibersite), condensed phosphates, and reduced oxidation state phosphorus compounds, which could have been available on early earth, are exposed to aqueous ammonia solutions. DAP is shown to remain in aqueous solution under conditions where phosphate is precipitated out by divalent metals. These results show that nitrogenated analogues of phosphate and reduced phosphite species can be produced and remain in solution, overcoming the thermodynamic barrier for phosphorylation in water, increasing the possibility that abiotic phosphorylation reactions occurred in aqueous environments on early earth.

Solvothermal preparation of Ag nanoparticle and graphene co-loaded TiO2 for the photocatalytic degradation of paraoxon pesticide under visible light irradiation

Keihan, Amir Homayoun,Hosseinzadeh, Reza,Farhadian, Mousa,Kooshki, Hamid,Hosseinzadeh, Ghader

, p. 83673 - 83687 (2016/11/05)

The growing use of organophosphorus compounds such as paraoxon as agriculture pesticides results in their accumulation in soils and groundwater. Therefore there is a high demand for developing efficient methods for removing these materials from contaminated environmental resources. In this study, Ag nanoparticle and graphene co-loaded TiO2 with various contents of Ag and graphene was prepared via a facile surfactant free solvothermal method in a mixture of water and ethanol solvents and was applied, for the first time, for the photocatalytic degradation of paraoxon (as a model organophosphorus compound) under visible light irradiation. In this ternary nanocomposite, the presence of Ag nanoparticles is for narrowing the band gap to the visible region due to its surface plasmon resonance (SPR) effect and the presence of graphene is for diminishing the recombination rate of the photogenerated electron and holes due to its high electrical conductivity. The results of photocatalytic activity tests demonstrate that the nanocomposite with 6% wt Ag and 1% wt graphene content has the best photocatalytic activity among the products. Investigation of the chemical state of the nanocomposites showed that the covering of Ag nanoparticle loaded TiO2 with a high weight ratio of graphene resulted in the formation of Ag-O bonds through bonding of Ag to the oxygen functional groups of graphene which causes a decrease of the SPR effect of Ag and by this way decreases the photocatalytic activity. Gas Chromatography-Mass Spectrometry (GC-MS) was used as analytical tool for determination of the photocatalytic reaction intermediates. GC-MS analysis results show that photodegradation of paraoxon produces 4-nitrophenol, di-ethylphosphate, mono-ethylphosphate, hydroquinone and hydroxyhydroquinone as major intermediates and subsequent photodegradation of these results in complete mineralization of paraoxon.
