Nitrobenzene

Zouping Jinxing Tshuaj Co., Ltd. Yog tias koj yuav mus rau cov lag luam wholesale bulk nitrobenzene 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: daj ntseg daj mus rau xim oily kua; cov khoom ntshiab yog ze li tsis muaj xim, thaum qib kev lag luam tshwm daj -ntsuab vim muaj cov dinitrobenzenes; muaj tus yam ntxwv iab almond tsw.
Kub taw tes: 210.8 degree; Melting point: 5.7℃(crystalizes ntawm qhov kub thiab txias).
Qhov ceev: 1.198 g / cm³ (ntawm 25 degree); hnyav dua dej.
Flash point: Kwv yees li ntawm . 88℃(lub khob kaw) → Cov kua hluav taws xob hluav taws xob (GHS Qeb 4 cov kua nplaum nplaum, tab sis nyuaj rau ignite).
Vapor siab: kwv yees li . 0.25 mmHg ntawm 25℃; evaporates maj mam, tab sis lub vapor yog 4.2 lub sij hawm hnyav dua li huab cua thiab nyhav mus rau hauv av.
Solubility: me ntsis soluble hauv dej (0.19 g / 100 mL ntawm 20 degree); miscible nrog ethanol, diethyl ether, benzene, chloroform, thiab acetone; ua hauj lwm raws li ib tug zoo heev hnyav rau ntau cov organic tshuaj.
Kev ruaj ntseg: zoo li ruaj khov nyob rau hauv ib txwm muaj, tab sis muaj kev phom sij thaum raug kub hnyiab, qhib nplaim taws, lossis muaj zog txo cov neeg ua haujlwm; undergoes sulfonation thaum lub sij hawm sib cuag nrog cov acids muaj zog.

Resistant oxidation thiab electrophilic hloov pauv: Cov pab pawg -NO₂ muaj zog electron- rho tawm, deactivating lub nplhaib benzene; halogenation los yog nitration yuav tsum tau hnyav hnyav.
Kev txo qis: Raws li cov xwm txheej xws li Fe / HCl, Sn / HCl, lossis H₂ / Pd → aniline (nws thawj qhov kev siv yog kev tsim cov aniline).
Birch txo: kua ammonia / alkali hlau → 1,4-dihydrobenzene derivatives.
Dawb- cov tshuaj tiv thaiv radical: tuaj yeem ua tus txais hluav taws xob, koom nrog SET txheej txheem; ua hauj lwm raws li ib tug sensitizer nyob rau hauv tej yam photochemical tshuaj.

Aniline ntau lawm: Tshaj 90% ntawm lub ntiaj teb nitrobenzene yog siv rau catalytic hydrogenation los tsim aniline (rau MDI, roj hmab additives, thiab dye precursors).
Cov kuab tshuaj: yav tas los siv los ua cov kuab tshuaj rau cov roj hmab ntuj, resins, thiab fatty acids; loj hloov tam sim no vim toxicity.
Flavoring: Siv cov khoom me me los ua kom zoo nkauj ntawm iab iab almonds lossis cherries (tam sim no feem ntau txwv rau hauv cov khoom noj khoom haus thiab hloov los ntawm kev nyab xeeb xws li hluavtaws benzylidene acetone).
Organic synthesis intermediate: Siv nyob rau hauv cov synthesis ntawm p-aminophenol (ib raw khoom rau paracetamol), azo dyes, thiab quinoline alkaloids.

GHS: H301 Toxic yog nqos; H311 Toxic nyob rau hauv kev sib cuag nrog daim tawv nqaij; H331 Toxic yog nqus tau; H373 Tej zaum yuav ua rau lub siab puas tsuaj los ntawm kev raug ncua ntev; H411 ​​Muaj tshuaj lom rau cov tsiaj hauv dej nrog rau ntev - cuam tshuam.
Toxicological mechanism: Metabolically txo (tshwj xeeb tshaj yog los ntawm dermal absorption) rau aniline derivatives, oxidizing hemoglobin rau methemoglobin (MetHb) thiab ua rau poob ntawm oxygen- nqa peev → cyanosis, dyspnea, methemoglobinemia; kuj ua rau daim siab puas, hemolysis, thiab CNS kev nyuaj siab.
Mob toxicity: nas qhov ncauj LD50 ~ 590 mg / kg (tshuaj lom; tsis tshua muaj tshuaj lom, tab sis yeej tsis yog qhov qis dua); dermal absorption yog thawj txoj hauv kev ntawm kev ua haujlwm lom lom - tsis txhob rub sab nraub qaum tawm tsam nws txawm tias hnav hnab looj tes.
Kev tuav: Siv cov fume hoods thiab tag nrho cov txheej txheem hloov chaw; hnav hnab looj tes nitrile (xyuas tsis tu ncua rau kev puas tsuaj), tsom iav kev nyab xeeb, thiab lub tshuab ua pa (nrog cov pa roj carbon monoxide); tsis txhob kub hauv cov hlab ntsha qhib.
Cia & Thauj: Khaws rau hauv cov thawv kaw kom deb ntawm lub teeb ntawm<40°C; keep away from strong reducing agents (e.g., zinc dust, sodium dithionite), strong acids (exothermic reaction upon contact), and ignition sources; absorb spills with sand or earth; prevent entry into sewers (due to persistent aquatic toxicity).
Kev tua hluav taws: Siv ua npuas dej, CO₂, lossis tshuaj qhuav qhuav; combustion ua rau NOx fumes; Cov neeg tua hluav taws xav tau SCBA.
