Wopanga Mtengo Wabwino wa Phosphorous Acid CAS:13598-36-2

Mtengo Wabwino Wopanga Phosphorous Acid CAS:13598-36-2 Chithunzi Chodziwika

kufotokozera mwachidule:

Asidi ya phosphorous ndi chinthu chapakati pakukonzekera zinthu zina za phosphorous. Asidi ya phosphorous ndi chinthu chopangira ma phosphonates kuti agwiritsidwe ntchito m'madzi monga kuwongolera chitsulo ndi manganese, kuletsa ndi kuchotsa skewere, kuletsa dzimbiri ndi kukhazikika kwa chlorine. Mchere wa alkali metal (phosphites) wa phosphorous acid ukugulitsidwa kwambiri ngati mankhwala ophera fungicide a zaulimi (monga Downy Mildew) kapena ngati gwero labwino kwambiri la zakudya za phosphorous kuchokera ku zomera. Asidi ya phosphorous imagwiritsidwa ntchito pokhazikitsa zosakaniza za pulasitiki. Asidi ya phosphorous imagwiritsidwa ntchito poletsa kutentha kwambiri kwa pamwamba pa zitsulo zomwe zimayambitsa dzimbiri komanso kupanga mafuta ndi zowonjezera mafuta.

Asidi ya phosphorous, H3PO3, ndi diprotic (imapanga ma proton awiri mosavuta), osati triprotic monga momwe fomula iyi inganenere. Asidi ya phosphorous ndi gawo lapakati pakukonzekera mankhwala ena a phosphorous. Popeza kukonzekera ndi kugwiritsa ntchito "phosphorous acid" kwenikweni kumakhudzana kwambiri ndi tautomer yayikulu, phosphonic acid, nthawi zambiri imatchedwa "phosphorous acid". Asidi ya phosphorous ili ndi formula ya mankhwala ya H3PO3, yomwe imafotokozedwa bwino ngati HPO(OH)2 kuti iwonetse khalidwe lake la diprotic.

Kugwiritsa Ntchito Phosphorous Acid

1. Phosphorous acid imagwiritsidwa ntchito popanga mchere wa phosphate wa feteleza monga potassium phosphite, ammonium phosphite ndi calcium phosphite. Imagwira ntchito kwambiri popanga ma phosphite monga aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) ndi 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), omwe amagwiritsidwa ntchito pochiza madzi ngati sikelo kapena choletsa kuwonongeka. Imagwiritsidwanso ntchito muzochita za mankhwala ngati chochepetsera. Mchere wake, lead phosphite imagwiritsidwa ntchito ngati PVC stabilizer. Imagwiritsidwanso ntchito ngati choyambira pokonzekera phosphine komanso ngati chothandizira pokonzekera mankhwala ena a phosphorous.
2. Phosphorous acid (H3PO3, orthophosphorous acid) ingagwiritsidwe ntchito ngati chimodzi mwa zigawo zomwe zimayambitsa kupanga zotsatirazi:
α-aminomethylphosphonic acids kudzera mu Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids kudzera mu amidoalkylation kenako ndi hydrolysis
Ma α-aminophosphonic acids otetezedwa ndi N (phospho-isosteres a amino acids achilengedwe) kudzera mu amidoalkylation reaction
3. Ntchito Zamakampani: Chosonkhanitsa ichi chapangidwa posachedwapa ndipo chimagwiritsidwa ntchito makamaka ngati chosonkhanitsa chapadera cha cassiterite kuchokera ku miyala yokhala ndi kapangidwe ka gangue kovuta. Pogwiritsa ntchito phosphonic acid, Albright ndi Wilson adapanga mitundu yosiyanasiyana ya zosonkhanitsa makamaka kuti zizitha kuyandama kwa mchere wa oxidic (monga cassiterite, ilmenite ndi pyrochlore). Palibe zambiri zomwe zimadziwika za momwe osonkhanitsa awa amagwirira ntchito. Kafukufuku wochepa wochitidwa ndi miyala ya cassiterite ndi rutile wasonyeza kuti ena mwa osonkhanitsawa amapanga thovu lalikulu koma anali osankha kwambiri.
