N-hexane

product-176-163

1.Basic Properties

Tshuaj Formula: C₆H₁₄ (ncaj-cov qauv saw, sib txawv ntawm cov isomers zoo li isohexane thiab neohexane)

Qhov tshwm sim: Tsis muaj xim, pob tshab kua nrog roj av -zoo li tsw

Volatility: Siab kub

Solubility: Insoluble hauv dej, miscible nrog feem ntau cov kuab tshuaj organic (xws li, ethanol, ether, acetone)

2. Kev siv tseem ceeb

Industrial Solvent: Siv rau kev rho tawm cov roj zaub (xws li roj taum pauv, roj canola), roj hmab, nplaum, thiab txheej txheej

Tus neeg saib xyuas huv: Degreasing thiab ntxuav cov khoom siv hluav taws xob, tshuab luam ntawv, thiab cov khoom siv tawv

Kev siv chav kuaj: Tsis yog -polar solvent hauv chromatography

Tshuaj Raw Khoom: Polymerization hnyav hauv kev tsim cov khoom siv polymer (xws li polypropylene)

3.Health Risks (Key Warning)

Mob Ua Phem: Siab -kev nqus pa tuaj yeem ua rau kiv taub hau, xeev siab, tshuaj loog, thiab tsis meej pem

Mob Neurotoxicity: Ntev-ntev raug (tshwj xeeb yog los ntawm kev nqus pa lossis nqus ntawm daim tawv nqaij) tuaj yeem ua raun-Hexane-induced Peripheral Neuropathy, characterized los ntawm:

Thaum ntxov: loog thiab tsis muaj zog ntawm tes / taw, kev puas siab puas ntsws (xws li, "khoom noj khoom haus- hnab looj tes" faib)

Kev loj hlob: Cov leeg nqaij atrophy, tsis khov kho, thiab txawm tuag tes tuag taw

Exposure Routes: Feem ntau hauv cov chaw ua haujlwm (piv txwv li, kev tsim khau, luam ntawv, tu tshuab hluav taws xob); kev pheej hmoo ntawm kev tsim txom los ntawm kev nqus pa ("huffing")

4. Kev ceev faj txog kev nyab xeeb

Engineering Controls: Cov chaw ua haujlwm yuav tsum muaj qhov cua zoo thiab kaw kaw

Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE): Tshuaj-cov hnab looj tes tiv thaiv (nitrile roj hmab), tsom iav kev nyab xeeb, ua kom lub ntsej muag carbon (cua- muab lub tshuab ua pa xav tau rau qhov siab)

Kev Tiv Thaiv Kev Tiv Thaiv thiab Kev Txhaum Cai: Khaws kom deb ntawm qhov hluav taws kub kub (hnyav heev); khaws cia rau hauv qhov chaw txias, qhov cua kom deb ntawm cov dej ntws. Nyob rau hauv rooj plaub ntawm nchuav, nqus nrog xuab zeb / av; Tsis txhob tso dej rau hauv cov kav dej.

First Aid:

Kev sib cuag ntawm daim tawv nqaij: Ntxuav kom huv nrog dej kom ntau

Inhalation: Txav mus rau huab cua ntshiab

Kev noj haus: Tsis txhob ntuav ntuav (kev pheej hmoo ntawm aspiration pneumonia); nrhiav kev kho mob tam sim ntawd

5.Environmental & Regulatory Information

Environmental Fate: Volatilizes yooj yim rau hauv cov huab cua, qhov twg nws tuaj yeem degraded los ntawm cov tshuaj tiv thaiv photochemical; Cov dej nchuav tuaj yeem ua rau cov av thiab dej hauv av

Cov ntaub ntawv tswj hwm:

Tuam Tshoj (Catalogue ntawm Hazardous Chemicals): Sau npe ua kua ua kua thiab muaj kev phom sij rau kev noj qab haus huv

OSHA (US): Chaw ua haujlwm raug txwv - 50 ppm (8-teev TWA)

IARC: Tsis tau muab cais ua cov carcinogen (txawm li cas los xij, nws cov metabolite 2,5-hexanedione cuam tshuam nrog neurotoxicity)

Cov ntsiab lus

n-Hexane yog ib qho kev lag luam hnyav. Nws qhov teeb meem tseem ceeb yogmob paj hlwb puas, uas yuav tsum tau tiv thaiv los ntawm nruj qhov cua thiab kev tiv thaiv kev ntsuas. Yog tias koj muaj kev qaug dab peg tom qab kev ua haujlwm raug, kev kuaj xyuas cov hlab ntsha sai yog pom zoo.
