Daim ntawv thov
1. 2-Picoline feem ntau yog siv los ua ntau yam nruab nrab hauv kev sib xyaw ntawm cov tshuaj (xws li ntev - ua sulfonamides thiab tiv thaiv - tshuaj silicosis), agrochemicals, dyes, thiab roj hmab accelerators .
2. 2-Picoline CAS 109-06-8 ua haujlwm ua ntej hauv kev tsim tshuaj lom neeg rau kev tsim 2-vinylpyridine, picolinic acid, thiab nitrapyrin, thiab tseem siv los ua cov kuab tshuaj thiab cov tshuaj reagent.
3. 2-Picoline yog ua haujlwm raws li tus qauv tsw thiab tsw ntxhiab hauv kev tswj xyuas cov khoom noj thiab cov khoom kom zoo nkauj, thiab yog ib qho tsw tsw ntxhiab tsw uas tau txheeb pom hauv cov qhob noom xim kasfes tsaus nti thiab cov noob txiv roj roasted .
4. Cov kws tshawb fawb siv 2-picoline hauv cov txheej txheem hluavtaws los npaj dearomatized, allylated, thiab carbon-hydrogen bond activated pyridine derivatives, nrog rau hauv kev tshawb fawb ntawm electron thiab proton hloov cov tshuaj tiv thaiv .
Cia thiab ceev faj
1. 2-Picoline yuav tsum tau muab cia rau hauv lub thawv kaw nruj nreem nyob rau hauv cov roj inert (nitrogen) nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua nyob ib puag ncig, kom deb ntawm tshav kub, sparks, thiab qhib nplaim taws; pom zoo cia ntawm chav tsev kub nyob rau hauv ib qho chaw txias, tsaus qhov chaw hauv qab no 15 degree.
2. 2-Picoline CAS 109-06-8 yog cais ua kua flammable (Qeb 3) nrog lub teeb nyem ntawm 26-29℃(kaw khob), thiab yuav tsum tau ceev kom deb ntawm cov muaj zog oxidizing agents, acids, thiab tooj liab alloys.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv (nitrile roj hmab), nruj nruj tsom iav kev nyab xeeb nrog rau sab- cov ntaub thaiv npog, tiv thaiv lub ntsej muag, thiab nplaim taws- cov khaub ncaws tiv thaiv zoo li qub thaum tuav 2-Picoline .
4. 2-Picoline yog hygroscopic thiab miscible nrog dej; 2-Picoline CAS 109-06-8 decomposes ntawm kev kub hnyiab, emitting cov pa phem ntawm nitrogen oxides (NOx), thiab cov ntaub ntawv tsis sib xws muaj xws li sulfuric acid, hlau, hlau (II) sulfate, thiab hydrogen peroxide.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav tam sim ntawd, xyuas kom muaj qhov cua txaus, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab hnav cov khoom siv tiv thaiv tus kheej nrog rau tus kheej -cov cuab yeej ua pa (SCBA) thiab tshuaj tiv thaiv kab mob.
2. Sau 2-Picoline CAS 109-06-8 siv cov cuab yeej tsis muaj hluav taws xob thiab tawg; rau cov nchuav me me, nqus nrog cov khoom siv tsis zoo xws li xuab zeb, diatomite, lossis universal binders, thiab muab tso rau hauv cov thawv ntim tsim nyog rau kev pov tseg.
3. Tsis txhob tsim cov vapors lossis pos huab thaum ntxuav kom tiv thaiv kev ua pa; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws, cov chav dej, lossis ib puag ncig vim nws muaj kev phom sij rau cov dej hauv dej.
4. Tshem tawm cov khoom pov tseg raws li cov khoom pov tseg uas muaj kev phom sij raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig los ntawm kev tso cai tshuaj tua kab mob lossis kev tswj kev tua hluav taws, ceeb toom UN2313 kev faib tawm nrog pawg III.
Kev tiv thaiv hluav taws
1. 2-Picoline yog cov kua hluav taws kub uas muaj qhov taw tes ntawm 26℃(kaw khob) thiab qhov txwv tsis pub tawg ntawm 1.4% txog 8.6% hauv huab cua; Cov vapors tuaj yeem tsim cov khoom tawg nrog cua ntawm qhov kub siab tshaj 26 degree.
2. Siv cawv- ua npuas ncauj resistant, qhuav tshuaj hmoov, carbon dioxide, los yog dej tshuaj tua hluav taws uas muaj cov khoom; Tsis txhob siv lub dav hlau dej ncaj qha raws li 2-Picoline CAS 109-06-8 tuaj yeem tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav nws tus kheej- muaj cov cuab yeej ua pa hauv siab- thov, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov kub hnyiab 2-Picoline vim muaj cov pa phem decomposition (cov pa phem ntawm nitrogen oxides thiab carbon oxides).
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; txav cov thawv los ntawm qhov chaw tua hluav taws yog tias muaj kev nyab xeeb ua li ntawd, txias cov thawv ntim nrog cov tshuaj tsuag dej los ntawm qhov chaw tiv thaiv, thiab muaj hluav taws kub los tiv thaiv ib puag ncig.
