Isopropyl cawv yog dab tsi thiab nws siv li cas?
CAS 67-63-0 Isopropyl cawv (2-propanol), tseem hu ua isopropanol lossis IPA, nws yog xim tsis muaj xim, flammable organic compound nrog cov ntxhiab tsw ntxhiab tsw. Raws li ib pawg isopropyl txuas nrog pawg hydroxyl, nws yog qhov piv txwv yooj yim tshaj plaws ntawm cov cawv thib ob,Isopropyl cawvyog cov tshuaj tua kab mob ntau tshaj plaws thiab siv dav hauv cov chaw muag tshuaj, tsev kho mob, chav huv, thiab cov khoom siv hluav taws xob lossis khoom siv kho mob.
Vim li cas 70% isopropyl cawv (IPA) yog cov tshuaj tua kab mob zoo dua li 99% isopropanol?
70% isopropyl cawv IPAtua kab mob los ntawm dissolving lawv cell membranes. Piv txwv li, nws nyuaj rau rhuav tshem cov txheej tiv thaiv nyias ntawm Gram- cov kab mob tsis zoo. Qhov no yog vim li cas nws thiaj li feem ntau hu ua kws tshuaj - qib cawv.
Dej yog qhov zais cia rau nws cov txiaj ntsig. Nws ua haujlwm pab, pab txhawm rau txhawm rau cov proteins hauv cov kab mob 'cell membranes. 30% dej ntsiab lus ntawm 70% isopropyl cawv ua rau cov tshuaj nkag mus rau hauv cov kab mob hlwb. Thaum sab hauv, nws clumps tag nrho cov proteins ua ke, tua cov kab mob tag nrho.
Tsis tas li ntawd, 70% IPA evaporates qeeb dua li 99% isopropanol. Qhov no txhais tau hais tias nws tseem nyob ntawm qhov chaw ntev dua, muab sijhawm ntau rau kev tawm tsam cov kab mob.
Hloov pauv, 99% isopropanol (yuav luag cov cawv ntshiab) muaj zog heev. Nws instantly clumps cov proteins ua ke nyob rau saum npoo ntawm cov kab mob, tsim ib tug nyuaj tiv thaiv txheej. Cov txheej no tiv thaiv cov cawv los ntawm cov kab mob. Cov kab mob tsis tuag; nws cia li mus dormant thiab tseem tuaj yeem ua rau muaj kev phom sij tom qab.
Nco ntsoov tias yog lubisopropyl cawv IPAconcentration poob qis dua 50%, nws cov tshuaj tua kab mob poob qis heev. Cov ntsiab lus siab dua (xws li 99%) yeej tsis tshua muaj txiaj ntsig ntawm kev tua kab mob.
