Ethanol Vs IPA isopropyl cawv: Cov khoom siv tshuaj
- Cov roj formula: C₃H₈O
- Kub taw tes: 82.6℃(180.7℃F)
- Evaporation: ceev ceev, tawm tsawg kawg nkaus residue
- Toxicity: Muaj tshuaj lom ntau dua yog tias noj
- Solubility: Tag nrho miscible nrog dej
Ethanol:
- Cov roj formula: C₂H₆O
- Kub taw tes: 78.5℃(173.3℃F)
- Evaporation: Slower piv rau IPA
- Toxicity: qis dua IPA, tab sis nruj nruj raws li kev haus cawv
- Solubility: Tag nrho miscible nrog dej
Puas yog isopropyl cawv IPA (CAS 67-63-0) muaj zog dua ethanol (CAS 64-17-5)?
IPA tsis yog universally "muaj zog" dua li ethanol (ethyl cawv); lawv muaj zog sib txawv.
Rau kev tua kab mob (tua cov kab mob): Ethanol (70-80%) yog qhov zoo dua me ntsis tiv thaiv ntau yam kab mob thiab kab mob. Ob leeg muaj txiaj ntsig zoo thaum siv ntawm lawv qhov kev pom zoo ntawm thaj tsam 70%.
Kev ntxuav thiab degreasing: IPA (99%) yog qhov zoo dua. Nws yog cov kuab tshuaj zoo dua rau cov roj, fluxes thiab adhesives, evaporates sai dua thiab yoojyim tsis muaj residue, uas yog vim li cas nws yog tus qauv rau kev ntxuav hluav taws xob.
Rau tib neeg noj: Ethanol yog tib txoj kev xaiv. IPA yog tshuaj lom thiab lom yog tias noj.
Kev nyab xeeb thiab kev txiav txim siab
Ob leeg cawv xav tau kev tuav pov hwm kev nyab xeeb thiab kev ua raws cai.
Isopropyl cawv IPA: Muaj tshuaj lom ntau dua yog tias noj, tab sis tsawg dua tswj tag nrho.
Ethanol: Kev tswj hwm hnyav vim nws siv hauv cov khoom siv; purity thiab denaturing qauv siv.
Vim li cas thiaj xaiv Gneebio?
Peb cov kua isopropyl cawv IPA (CAS 67-63-}0), muaj nyob rau hauv ntau yam ntawm cov concentrations (los ntawm 70% mus rau 99.9+}%), yog tsim thiab kuaj kom tau raws li cov qauv kev lag luam siab tshaj plaws. Txhua batch tau txais kev tswj hwm zoo, suav nrog GC-MS kev sim, kom ntseeg tau tias cov ntsiab lus hlau ion tsawg dua lossis sib npaug rau 1ppb (rau cov qib siab ntshiab) thiab noo noo tsawg dua lossis sib npaug li 0.03%. Tau ntawv pov thawj los ntawm ISO 9001, REACH, thiab FDA, peb IPA ua tau raws li cov qauv thoob ntiaj teb rau kev ntxuav hluav taws xob, tshuaj synthesis, muaj kuab tshuaj, thiab tshuaj tua kab mob.
