phosphorous acid toxicity

Yellow phosphorus is used in manufacturing fireworks and fertilizers. (4) Uses Most phosphorus is used in the production of phosphoric acid and phosphates, which are used in the fertilizers industry. Urgent hospital treatment is likely to be needed. If swallowed do NOT induce vomiting. Treatment of triaryl phosphites with phosphorous acid at temperatures over 60 °C provides good yields of diaryl H-phosphonates (Fig. phosphorus poisoning Poisoning caused by the ingestion of substances containing yellow phosphorus, such as rat poison or roach poison. Downy mildew is caused by the fungus-like organism Plasmopara viticola and is … It is a white solid. cornmoditics when ~~sctl as a11 agric~~it~~ral fui~g~cide on food crops.' 4.20.1) (81).The reaction occurs in two stages. When mixed with water, it forms a strong acid called phosphonic acid. Phosphorus trichloride reacts spontaneously with moisture to form hydrochloric acid (cloud) and phosphorous acid. Phosphorous acid EC Inventory, Pre-Registration process, CAD - Chemical Agents Directive, Art. Phosphorous acid, tri-C12-14-alkyl esters EC Number: 297-701-9 EC Name: Phosphorous acid, tri-C12-14-alkyl esters CAS Number: 93686-48-7 Molecular formula: C36H75O3P C38H7903P C40H83O3P C42H87O3P IUPAC Name: Phosphorous acid, tri-C12-14-alkyl esters sodium and potassi~im salts in or oil :ill iooti . (See also Stability and Reactivity section). Phosphorus is found naturally in many foods and phosphoric acid is used as an additive, so most people get enough in their diet. Measuring table showing tank size and rates of phosphorous acid needed to produce low, high, and toxic rates of ProPhyt. Phosphorus poisoning (PP) occurs after accidental exposure to white (also synonymously termed yellow) phosphorus. Phosphorous acid - Identification, toxicity, use, water pollution potential, ecological toxicity and regulatory information Note : See Working with the Information on this Page section below for important notes about this data. Pints of ProPhyt to produce: Tank size Gallons Low rate 0.375% High rate 0.500% Toxic … Acute toxicity, Oral (Category 4), H302 Skin corrosion (Category 1A), H314 Classification according to EU Directives 67/548/EEC or 1999/45/EC C Corrosive R35 Xn Harmful R22: Label elements: Pictogram: GHS05 acid acid GHS07 exclam exclam: Signal word Danger Hazard statement(s) H290 May be corrosive to metals. (4) Phosphorus compounds have some advantages compared to BFRs. Forms yellow deposits in aqueous solution that are spontaneously flammable upon drying. Further possibilities include inhalation of white phosphorus and its accidental ingestion. Phosphorous acid is not a naturally occurring substance and has a mixed mode of action involving direct toxicity to the plant pathogen, aided by natural plant defenses. 6. Absorbs oxygen from the air to form phosphoric acid [Hawley]. the ‘source substance’ to read across to the applied substance, i.e. In addition, data on toxicokinetics, combined chronic toxicity/carcinogenicity and delayed neurotoxicity have been submitted for phosphorous acid, tris (2,4‐di‐tert‐butylphenyl) ester (Figure 2; FCM No 671, CAS No 31570‐04‐4), i.e. Forms yellow deposits in aqueous solution that are spontaneously flammable upon drying. During a fire toxic by-products are created from BFRs. Updated. I his smrenic!ir 1: incorrect, as the Mineral ;~cids RED does not include phosphorous acid.
