Phosphoous acid, Kuphatikizika kosiyanasiyana ndi mtundu wa mankhwala h3po3. Ndi ufa woyera wa kristoline, kusungunuka mosavuta m'madzi ndi Mowa, ndipo pang'onopang'ono oxidiated mu orthophisphate mumlengalenga. Phosphite ndi dibasic acid, acidity yake imakhala yolimba pang'ono kuposa phosphoric acid, imachepetsa katundu wa siliva (AG), Ili ndi hygrosophicity ndi kupulumutsidwa, ndipo ndizachilengedwe. Phosphite imagwiritsidwa ntchito makamaka ngati kuchepetsa mankhwala, naloni wowala bwino, komanso amagwiritsidwanso ntchito ngati zida za phosphori yazitsulo, mankhwala osokoneza bongo ndi othandizira madzi opangira zipatso.
Katundu:ufa woyera wa crystalline. Sungunulani m'madzi ndi mowa. - 1.6514g / cm3, malo osungunuka: 73 ℃, owira: 200 ℃.
Karata yanchito:
1.Phosphoous acidimagwiritsidwa ntchito kupanga mchere wa feteleza wa phosphate ngati potaziyamu phosphite, ammonium phosphite ndi calcium phosphite. Zimakhudzidwa mwachangu pokonza ma phosphphites Kugwiritsa ntchito mankhwala ochizira madzi ngati sikelo kapena choletsa choletsa. Amagwiritsidwanso ntchito pamachitidwe opatsirana ngati wothandizira wothandizira. Mchere wake, utsogoleri wake umagwiritsidwa ntchito ngati PVC Stabilizerser. Amagwiritsidwanso ntchito ngati chotsogola pokonza phosphine ndipo monga wapakatikati pakukonzekera zina za phosphorous.
2.Phosphoous acid.
α-aminomethylphosphonosphonic acids kudzera panjinnich-mtundu mikono yambiri
1-aminolkinephosphosphosphosphosfunos acids via amidokyty amatsatiridwa ndi hydrolysis
N-Aminophosphosphonic acids (Phospho-ISOSTEREESS AMINO ADids) kudzera mu Amidokyy
3. Kugwiritsa ntchito mafakitale: Wotolera uyu adapangidwa posachedwapa ndipo adagwiritsidwa ntchito ngati otola ndi cassiteric acid, albright ndi Wilson adapanga magulu a phosgonic michere ya oxidic ( Ie Cassiterite, Ilmemete ndi Pyrochlore). Zochepa kwambiri zimadziwika za magwiridwe antchito awa. Maphunziro ochepa omwe amachitika ndi Cassiterite ndipo Rutule Ores adawonetsa kuti ena mwa osonkhetsa awa amatulutsa frominous frominous ndikusankha bwino.
Njira Yopangira:
Njira zopanga mafakitale zimaphatikizapo ma trichlororoc phosphorous ndi phosphoric acid mchere. Njira ya hydrolysis imawonjezera madzi ku hydrolysis zomwe zimasakanikirana ndi trichloride kuti mupange sub -phosphororic acid. Pambuyo pochotsa, kuchuluka kwa mankhwala ozizira, crystallization ndi kusataya mtima kumapangidwa, ndipo chomalizidwa chimapangidwa. PCI3 + 3H2O → H3po3 + 3hcl imatulutsa haidrogen chloride chobwezeretsanso, zomwe zitha kupangidwa mu hydrochloric acid.
Chitetezo:
Makhalidwe Oseketsa Achilengedwe: mu HOD Hole chothandizira; Kutentha kuwongolera poizoni phosphoro oxide.
Makhalidwe osungira ndi mayendedwe: Kutentha kwa kutentha kochepa; Sungani payokha kuchokera ku hy h opanikizika ndi alkali.
Kulongedza: 25KG / Thumba
Kusungidwa: Sungani bwino chotsekedwa bwino, osagonjetseka, ndi kuteteza ku chinyezi.
