N-Hexane

Zouping Jinxing Chemical Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov muag khoom ntawm n-hexane hauv Suav teb. Yog tias koj yuav mus rau cov lag luam wholesale bulk n- hexane ua nyob rau hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Cov tsos mob: tsis muaj xim, pob tshab, muaj kuab heev; roj av-zoo li tsw
Melting point: -95.6 ° C
Boiling point: 68.7℃(kwv yees . 30℃qis dua n-heptane; approx. 70℃qis dua xylene)
Ceev: 0.659 g / cm³ (ntawm 20 degree; 34% lighter dua dej)
Flash point: -23℃(kaw khob)-Class I flammable; ntau volatile/hazard tshaj n-heptane (-4 degree)
Nws pib- qhov kub thiab txias: 225 degree
Refractive index: n²⁰_D 1.3749
Solubility: Insoluble hauv dej; miscible nrog ethanol, diethyl ether, chloroform, thiab roj; pom muaj zog tawg lub zog rau cov uas tsis yog - cov rog rog, waxes, thiab resins (rosin, terpene resins) tab sis zoo li insoluble hauv polar tshuaj
Kev ntsuam xyuas octane: RON ≈ 25 (me ntsis siab dua n-heptane, tseem tseem raug faib ua qis -octane alkane)

Cov roj zaub rho tawm: "Tsis yog. 6 hnyav" (cov kuab tshuaj rho tawm) siv rau cov kua txiv hmab txiv ntoo thiab cov roj rapeseed feem ntau yog n-hexane, uas tau rov qab los ntawm evaporation thiab rov ua dua tshiab (daim ntawv thov no suav nrog feem ntau ntawm kev noj thoob ntiaj teb).
Kev ua cov roj hmab: ceev- ziab kom qhuav rau cov roj- txuas ntxiv SBS/SEBS, nplaum txheej, thiab lub log tsheb dipping.
Electronics tu: Degreasing thiab tu ntawm Circuit Court boards, LCD cov ntxaij vab tshaus, thiab magnetic heads (yav tas los siv los hloov trichloroethylene, tab sis tam sim no loj hloov los ntawm n-heptane/IPA azeotropes vim neurotoxicity kev txhawj xeeb).
Chromatography: GC txhaj tshuaj hnyav, eluent rau qis -molecular- hnyav GPC (Gel Permeation Chromatography), thiab tsim tus neeg sawv cev rau TLC (Thin- Txheej Chromatography).
Organic synthesis: Inert nruab nrab rau dawb-radical halogenation thiab organolithium/Grignard cov tshuaj tiv thaiv (nyiam dua n-heptane rau qis- qhov kub thiab txias vim nws tsis khov ntawm qhov kub qis).

Mob toxicity: Tsawg toxicity (rat qhov ncauj LD₅₀ ≈ 28 g / kg); Txawm li cas los xij, vapors muaj cov tshuaj loog, thiab cov concentrations siab tuaj yeem ua rau tsis nco qab.
Kev lom neeg ua haujlwm ntev: n-Hexane yog ib qho paub txog peripheral neurotoxin; nws yog oxidized nyob rau hauv lub cev mus rau 2,5-hexanedione, uas khi rau neuronal tubulin, ua rau symmetrical loog nyob rau hauv lub distal extremities, cov leeg tsis muaj zog, thiab ko taw / dab teg poob-ib yam mob uas hu ua "rubber khau Hoobkas tuag tes tuag taw." kuv lub teb chaws teev cov kev txwv kev ua haujlwm (PC-TWA) ntawm 100 mg/m³ (xws li n-hexane; "skin" sau npe siv).
Toxicity amplification los ntawm impurities: Yog tias muaj- cov khoom qib muaj benzene (feem ntau hauv cov chaw qub), hematotoxicity yog compounded; tam sim no lub teb chaws cov qauv tswj hwm cov ntsiab lus benzene ntawm<0.1% in extraction solvent oils.
Carcinogenicity: Ntshiab n-hexane raug cais los ntawm IARC raws li Pawg 3; Txawm li cas los xij, kev ua haujlwm raug rau kev sib xyaw ua ke yog qhov tseeb txuas rau kev puas hlwb neurotoxic.
Flammability thiab tawg: tawg txwv yog 1.2%–7.7% (v/v); rhiab heev rau hluav taws xob static; qhib - sab saum toj hloov siv lub nruas yas yog txwv.
Kev tiv thaiv: tawg- cov cuab yeej pov thawj thiab lub qhov cua muaj zog yuav tsum tau; siv activated carbon lim cartridges (muab- cua tshuab pa rau siab concentrations); hnab looj tes nitrile (fluororubber yog superior; butyl roj hmab yog txaus); qhib nplaim taws thiab tsis yog- tawg- cov khoom siv hluav taws xob pov thawj raug txwv rau ntawm -site.
Cia thiab thauj: UN 1208, Chav Kawm 3, PG II; warehouse kub yuav tsum tau tswj hauv qab 35℃thaum lub caij ntuj sov huab cua.
