Igiciro cyiza cy'umukora aside fosifore CAS: 13598-36-2

ibisobanuro bigufi:

Aside fosforu ni igikoresho cy’ibanze mu gutegura ibindi bintu bya fosforu. Aside fosforu ni igikoresho fatizo gikoreshwa mu gutegura fosforu zo gutunganya amazi nko kugenzura icyuma na manganese, gukumira no gukuraho ibinini, kurwanya ingese no kubungabunga chlorine. Umunyu wa alkali metal (fosfites) wa aside fosforu uri kugurishwa cyane nk'umuti urwanya fungicide mu buhinzi (urugero: Downy Mildew) cyangwa nk'isoko nziza y'intungamubiri za fosforu mu bimera. Aside fosforu ikoreshwa mu gutuma ibintu bihinduka mu buryo buhamye. Aside fosforu ikoreshwa mu gukumira ubushyuhe bwinshi bw'ubuso bw'icyuma bushobora kwangirika no gukora amavuta n'ibindi bikoresho by'amavuta.

Ibisobanuro

Aside fosforo, H3PO3, ni diprotike (ishobora gushyiramo protoni ebyiri mu buryo bworoshye), ntabwo ari triprotike nk'uko byasobanuwe n'iyi formula. Aside fosforo ni igikoresho cyo hagati mu gutegura izindi mvange za fosforo. Kubera ko gutegura no gukoresha "aside fosforo" mu by'ukuri bireba cyane tautomer ikomeye, aside fosforo, ikunze kwitwa "aside fosforo". Aside fosforo ifite formula ya shimi H3PO3, igaragazwa neza nka HPO (OH)2 kugira ngo yerekane imiterere yayo ya diprotike.

Amagambo asa

Aside ya fosifore, isukuye cyane, 98%;

Fosforu trihydroxide; fosforustrihydroxide;

Trihydroxyfosfini; aside fosforasi, ikoreshwa mu gukamura;

Fosforusiti; aside fosforu, 98%, isukuye cyane; AURORA KA-1076

Imikoreshereze ya aside fosifore

1.Aside fosforasi ikoreshwa mu gukora umunyu wa fosforasi nk'umunyu wa potasiyumu fosforasi, ammonium fosforasi na fosforasi ya kalisiyumu. Igira uruhare runini mu gutegura fosforasi nka aminotris (aside methylenephosphonic) (ATMP), 1-hydroxyethane 1,1-diphosphonic aside (HEDP) na aside 2-phosphonobutane-1,2,4-tricarboxylic aside (PBTC), ikoreshwa mu gutunganya amazi nk'umuti ugabanya ubukana bw'amazi. Ikoreshwa kandi mu bikorwa bya shimi nk'ikintu kigabanya ubukana bw'amazi. Umunyu wayo, fosforasi y'icyitegererezo ikoreshwa nk'ikintu gikomeza PVC. Ikoreshwa kandi nk'intangiriro mu gutegura fosforasi no nk'igice cyo hagati mu gutegura ibindi bintu bya fosforasi.
2. Aside fosforasi (H3PO3, aside orthoforasi) 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.
