N-hexane
1. Cov ntaub ntawv yooj yim
1.1 Molecular Formula & Structure
Cov mis mos molecular: C6H14Structural formula: CH3CH2CH2CH2CH2CH3A ncaj-chain saturated alkane nrog rau carbon atoms thiab tsis muaj sab chains. Nws cov isomers suav nrog isohexane, neohexane, thiab lwm yam.
1.2 Qhov tshwm sim & tsw
Nyob rau hauv ib txwm kub thiab siab, nws yog ib tug tsis muaj kob pob tshab kua nrog ib tug faint petroleum tsw. Nws tsis tshua muaj soluble hauv dej, tab sis miscible nrog ethanol, ether, acetone, pentanes thiab txhua hom roj hauv ib qho kev faib ua feem.
2. Core Industrial Applications
2.1 Industrial Degreasing Cleaner (Pib Siv)
Siv rau degreasing thiab roj tshem tawm hauv electronics, hardware, optical lens thiab tawv industries; kuj tseem siv rau hauv kev luam ntawv thiab yas pwm tso roj ntxuav. ⚠️ Qhov tsis zoo: Cov tshuaj lom ntau dua li pentanes. Ntau lub tuam txhab tam sim no hloov mus rau qis - tshuaj lom cov tshuaj hydrocarbon xws li pentanes los hloov.
2.2 Extraction Solvent
Grain & roj kev lag luam: Cov khoom tseem ceeb ntawm No.6 extraction hnyav roj rau edible zaub roj leaching extraction.
Pharmaceutical & flavor industries: Tsawg-kub rho tawm cov roj yam tseem ceeb thiab cov khoom xyaw nquag los ntawm cov tshuaj ntsuab.
2.3 Tshuaj Raw Khoom
Cov kuab tshuaj rau cov organic synthesis thiab diluent rau cov tshuaj tiv thaiv polymerization; high-purity chromatographic-qib n-hexane ua haujlwm zoo rau kev soj ntsuam kuaj chromatographic.
2.4 Foaming & Dilution Additive
Tsis tshua muaj siv ib leeg rau foaming; feem ntau sib xyaw nrog pentanes los kho volatilization tus nqi rau qeeb - kho polyurethane systems.
3. Kev nyab xeeb & toxicity (Qhov txawv ntawm Pentanes)
3.1 Hazard Classification
UN 1208, Class 3 Flammable Liquid, Packing Group II.
3.2 Health Hazards (Core Risk)
Pentanes feem ntau ua rau mob anesthetic teebmeem, thaumn-hexane nqa cov tshuaj neurotoxicity tshwj xeeb:
Short- nqus tau pa: kiv taub hau, xeev siab, qaug zog thiab ua pa ua pa.
Lub sij hawm ntev - kis tau ntev: Peripheral neuropathy, loog ntawm tes thiab ko taw, leeg tsis muaj zog, taug kev teeb meem nrog kev puas tsuaj rov qab tsis tau. Kev sib cuag ntawm daim tawv nqaij ntev ua rau degreasing, chapping thiab dermatitis.
3.3 Kev Tiv Thaiv Cov Cai
Cov chaw ua haujlwm yuav tsum tau ua kom muaj cua nkag nrog tawg - cov khoom siv hluav taws xob pov thawj. Cov neeg ua haujlwm yuav tsum hnav lub qhov ncauj qhov ntswg thiab cov kuab tshuaj- cov hnab looj tes tiv thaiv. Lub sijhawm ntev ntawm daim tawv nqaij yog txwv tsis pub ua haujlwm, thiab qhov chaw ua haujlwm hauv huab cua yuav tsum tau tswj tsis pub dhau kev txwv kev ua haujlwm.
4. Kev Qhia Txog Kev Xaiv: n-Hexane vs n-Pentane / Isopentane
volatilization ceev, qis-kub foaming & qis neurotoxicity → Xaiv n-pentane lossis isopentane
Muaj zog yaj lub zog, qeeb evaporation & sib sib zog nqus roj extraction → Xaiv n-hexane
Noj cov roj rho tawm: Nyiam n-hexane; n-hexane tsuas yog siv rau cov ntaub ntawv thermal rwb thaiv tsev foaming.
5. Cov Lus Qhia Txog Kev Cia & Kev Thauj Mus Los
Lub tank thiab nruas yuav tsum tau muab kaw kom nruj, khaws cia rau hauv qhov txias thiab zoo - qhov cua qhov chaw nyob deb ntawm qhov chaw cua sov, qhib nplaim taws thiab oxidizing cov neeg ua haujlwm.
Tank yuav tsum tau grounded kom tshem tawm hluav taws xob zoo li qub; Kev sib txhuam zoo li qub yog txwv tsis pub nyob hauv cov chaw cia khoom.
Tsis muaj kev sib xyaw cia lossis thauj nrog cov oxidants muaj zog (hydrogen peroxide, chlorate, thiab lwm yam).
Carbon steel tso tsheb hlau luam tau txais kev thauj mus los; ISO TANK ntim yuav tsum ua raws li T3 / T4 tank specifications.
