aside fosifore，Ikinyabutabire kidahinduka gifite formula ya shimi H3PO3. Ni ifu y'umweru ikoze mu buryo bwa kristu, yoroshye gushonga mu mazi no muri ethanol, kandi ikavamo ogisijeni buhoro buhoro mu kirere. Fosfite ni aside dibasic, aside yayo irusha aside fosforerike imbaraga nke, ifite ubushobozi bwo kugabanya cyane, yoroshye kugabanya ions za silver (Ag+) ikaba ifeza (Ag), ishobora kugabanya aside sulfurike ikaba sulfure dioxide. Ifite ubushobozi bwo kugabanya cyane kandi ikanangiza, kandi irangiza. Fosfite ikoreshwa cyane cyane nk'ikintu kigabanya ubushyuhe, ikintu kigabanya ubushyuhe cya nylon, ariko kandi ikoreshwa nk'ibikoresho fatizo bya fosfeti, imiti yica udukoko n'ibikoresho fatizo byo gutunganya amazi bya fosfeti.
Imitungo:ifu y'umweru ikoze mu cyuma gitukura. Irashonga mu mazi no mu nzoga. Ubucucike: 1.651g/cm3, aho gushonga: 73℃, aho kubira: 200℃.
UBUSABIZI:
1.aside fosiforeIkoreshwa mu gukora umunyu wa fosifate w’ifumbire nka fosifate ya potasiyumu, fosifate ya ammonium na fosifate ya kalisiyumu. Igira uruhare runini mu gutegura fosifate nka aminotris (aside ya methylenephosphonic) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) na aside ya 2-phosphonobutane-1,2,4-tricarboxylic (PBTC), ikoreshwa mu gutunganya amazi nk'ikintu gikingira cyangwa kigabanya ubukana bw'amazi. Ikoreshwa kandi mu bikorwa bya shimi nk'ikintu kigabanya ubukana bw'amazi. Umunyu wayo, fosifate y'icyitegererezo ikoreshwa nk'ikintu gikomeza PVC. Ikoreshwa kandi nk'intangiriro mu gutegura fosifate no nk'igiceri mu gutegura ibindi bintu bya fosifate.
2.aside fosifore(H3PO3, aside orthophosphorous) ishobora gukoreshwa nk'imwe mu ngingo zigize reaction mu gukora ibi bikurikira:
aside α-aminomethylphosphonic binyuze mu buryo bwa Mannich-Type Multicomponent Reaction
aside 1-aminoalkanephosphonic binyuze muri amidoalkylation hanyuma hagakurikiraho hydrolysis
Aside α-aminophosphonic irinzwe na N (phospho-isostere za aside amine karemano) binyuze mu buryo bwa amidoalkylation
3. Imikoreshereze y’inganda: Iyi kusanya ry’amabuye y’agaciro ryakozwe vuba aha kandi ryakoreshejwe cyane cyane nk’ikusanya ryihariye rya cassiterite riva mu mabuye y’agaciro afite imiterere ikomeye ya gangue. Hashingiwe kuri aside fosfone, Albright na Wilson bari barakoze ubwoko butandukanye bw’ikusanya ry’amabuye y’agaciro akomoka kuri oxide (ni ukuvuga cassiterite, ilmenite na pyrochlore). Nta byinshi bizwi ku mikorere y’aya makusanya. Ubushakashatsi buke bwakozwe ku mabuye y’agaciro ya cassiterite na rutile bwagaragaje ko amwe muri aya makusanya akora ifuro ryinshi ariko yari asanzwe atoranya.
Uburyo bwo gukora:
Uburyo bwo gukora mu nganda burimo fosifore ya trikloroyike na aside fosforike. Uburyo bwo gukora hidrolize bwongera buhoro buhoro amazi muri hydrolize reaction munsi y’imvange ya trichloride kugira ngo hakorwe aside sub-phosphorike. Nyuma yo gutunganya, ChemicalBook ikonje, crystallization na sharply birakorwa, hanyuma umusaruro urangizwa ugakorwa. PCI3+3H2O → H3PO3+3HCL yayo ikora hydrogen chloride recycling mu gihe cyo kuyikora, ishobora gukorwamo aside hydrochloric.
Umutekano:
Ibiranga ibyago byo gushya: mu mwobo wa H ikoreshwa mu gutwika; Ubushyuhe buboza imyuka ya fosifore okiside irimo uburozi.
Ibiranga ububiko n'ubwikorezi: guhumeka mu bubiko, ubushyuhe buke, byumye; Bika ukwabyo n'ibikoresho birekura utwobo twa H n'ibikomoka kuri alkali.
Gupakira: 25kg/umufuka
Kubika: Bika ahantu hafunze neza, hadapfa urumuri, kandi ukingire ubushuhe.
