Mtengo Wabwino Big Stock Hypophosphorous acid CAS 6303-21-5 Colourless Liquid
Chemical Properties
Hypophosphorous acid ndi wothandizira kuchepetsa.Mphamvu ya monobasic acid.The amadzimadzi njira ndi acidic ndipo pang'onopang'ono oxidized mu mpweya kutentha firiji.Kulumikizana ndi H porogen kumayambitsa kuyaka.Kuyaka ndi chiwawa anachita ndi oxidizing wothandizira.Kuwola mpweya wapoizoni wa phosphine ndi kutentha kwakukulu, ngakhale kuphulika.Zowononga.Hypophosphorous acid nthawi zambiri amawonjezeredwa ku zakumwa zoziziritsa kukhosi chifukwa samayamwa.Chifukwa chake chiwopsezocho ndi chaching'ono, koma makamaka hypophosphorous acid imatha kuvulaza m'mimba.
Mfundo Zazikulu
Hypophosphorous acid, yomwe imadziwikanso kuti "hypophosphorous acid", ndi mafuta opanda mtundu kapena kristalo wonyezimira, ndipo ndi chinthu chofunikira kwambiri pamakampani opanga mankhwala.Cholinga chachikulu ndi kugwiritsidwa ntchito ngati kuchepetsa wothandizila kwa electroless plating, kuteteza kusinthika kwa phosphoric acid utomoni, ndipo angagwiritsidwenso ntchito ngati chothandizira ndi refrigerant chifukwa esterification anachita, makamaka kupanga mkulu-chiyero sodium hypophosphite.Pali njira zambiri zokonzekera, zomwe njira zokonzekera zodziwika bwino m'makampani zimaphatikizapo njira ya ion exchange resin ndi electrodialysis.
ZINTHU ZANGA ZOKHUDZA KWAMBIRI
Kagwiritsidwe:
1. Monga chochepetsera pakupanga mankhwala;
2. Ntchito kupewa kusinthika kwa phosphoric acid utomoni;
3. Ntchito ngati chothandizira esterification ndi refrigerant;
4. Amagwiritsidwa ntchito popanga hypophosphite, ndipo mchere wake wa sodium, mchere wa manganese, mchere wachitsulo, ndi zina zotero zimagwiritsidwa ntchito ngati mankhwala opatsa thanzi;
5. Amagwiritsidwa ntchito mu mankhwala komanso ngati kuchepetsa, reagents kudziwa arsenic, tellurium ndi kulekanitsa tantalum ndi niobium.
