Daim ntawv thov ntawm high-purity hexane
High-purity hexane yog ib qho tsis muaj kob, kua txob tsis zoo, yog siv cov khoom siv hluav taws xob zoo nkauj thiab lwm yam kev ntsuas nrog lwm cov xwm txheej
1.} siv raws li tsis yog-polar cov kuab tshuaj
Kev loj hlob hexane molecules, vim tias muaj tsuas yog cov pa roj carbon-hydrogen thiab cov kuab tshuaj polar, muaj cov kuab tshuaj lom neeg organic thiab sim .
2. ua ib qho extractant
High-purity hexane tuaj yeem cuam tshuam sai heev nrog qee yam khoom (cov tshuaj yeeb dej caw) thiab siv rau cov tshuaj lom neeg, ua rau muaj kev sib cais thiab extraction.
{{03. raws li cov khoom siv rau kem lub chromatography
Nyob rau hauv kem chromatograph sib cais, n-hexane yog ib feem tau siv tsis-pem roob hauv paus thiab cov khoom ntim, thiab feem ntau ua haujlwm rau enrich volatile tshuaj .
Qhov zoo ntawm high-purity hexane
High-purity hexane, raws li ib tug universal folvent, muaj cov txiaj ntsig hauv qab no:
1.} purity siab
High-purity hexane yog cov kuab heev, feem ntau siv los npaj cov olior organic reagents {}}
2. Zoo solubility
High-purity hexane tuaj yeem sai me tsis muaj ntau cov organic sib xyaw thiab yog ib feem siv cov kuab tshuaj {}}
3. Tsis muaj volatility zoo
High-purity hexane yog cov kua hluav taws xob siab heev . Alkyl pawg yog nquag ua rau loj thaum npaj cov kev daws teeb meem.
