PROSPHOROUS ACID
Phosphorous acid (H₃PO₃) yog xim tsis muaj kob, crystalline compound nrog ib tug me ntsis pungent tsw, paub txog nws muaj zog txo zog. Nws yog soluble hauv dej thiab decomposes thaum cua sov, tsim phosphine (PH₃) thiab phosphoric acid (H₃PO₄). Nws muaj cov qauv molecular nrog ib daim ntawv cog lus PH thiab ob daim ntawv cog lus P-OH, uas txawv nws ntawm phosphoric acid. Nws ua raws li diprotic acid, pub ob hydrogen ions hauv kev daws. Vim nws cov peev xwm txo qis, nws feem ntau siv hauv kev ua liaj ua teb ua cov tshuaj tua kab mob thiab hauv kev lag luam tshuaj los tsim lwm cov phosphite ntsev.

Phosphorous acid ua raws li stabilizer hauv kev tsim cov polymers, tshwj xeeb tshaj yog rau PVC thiab lwm yam halogenated yas. Thaum lub sij hawm polymerization, nws pab tiv thaiv kev tsis xav sab, xws li oxidation thiab degradation ntawm cov saw hlau polymer. Cov nyhuv stabilizing no txhim kho cov khoom siv kom ruaj khov, yoog raws, thiab lub neej ntev, uas yog qhov tseem ceeb rau kev siv hauv kev lag luam. Los ntawm kev ua kom muaj kev ncaj ncees ntawm cov khoom siv polymers, nws tau siv dav hauv kev tsim cov yas thiab pom cov ntawv thov hauv txhua yam los ntawm cov khoom siv rau cov khoom siv.
