Ib qho ntshiab, tsis muaj xim, flammable kua. Tus ntxhiab tsw. |
| Siv |
t-Butyl Isocyanate yog ib qho tseem ceeb hauv kev sib xyaw ua ke SCH 503034, ib qho tshuaj muaj peev xwm hauv kev kho tus kab mob siab C. Txoj kev tshawb no tham nrog cov ntaub ntawv cov tshuaj inhibitive selectivity tiv thaiv tus kab mob enzyme NS3 Protease. |
| Kev piav qhia dav dav |
Cov kua ntshiab tsis muaj xim nrog cov ntxhiab tsw. Flash point 68 degree F. Muaj tshuaj lom heev los ntawm kev noj tshuaj, kuj tseem tuaj yeem ua rau muaj tshuaj lom los ntawm daim tawv nqaij nqus thiab nqus tau pa. Vapors hnyav dua li huab cua. Tsawg dua dej thiab insoluble hauv dej. Vapors hnyav dua li huab cua. Tsim cov tshuaj lom oxides ntawm nitrogen thaum combustion. |
| Cua & Dej Reactions |
Cov nplaim taws heev. Tej zaum yuav hnov mob nrog dej los ua kom muaj kuab lom. Maj mam decomposed los ntawm dej. |
| Reactivity Profile |
tert-Butylisocyanate tuaj yeem hnov mob nrog cov amines, aldehydes, cawv, alkali hlau, ketones, mercaptans, muaj zog oxidizing tus neeg saib xyuas, hydrides, phenols, thiab peroxides. Tej zaum yuav raug polymerization nrog acids thiab bases. Tej zaum yuav hnov mob nrog dej los tsim tert-butylamine thiab carbon dioxide. Base-catalysed cov tshuaj tiv thaiv ntawm isocyanates nrog cawv yuav tsum tau nqa tawm hauv cov kuab tshuaj inert. Cov kev tshwm sim zoo li no thaum tsis muaj cov kuab tshuaj feem ntau tshwm sim nrog kev kub ntxhov [Wischmeyer 1969]. |
| Health Hazard |
TOXIC; nqus tau, noj los yog sib cuag (tawv nqaij, qhov muag) nrog vapors, plua plav lossis khoom yuav ua rau raug mob hnyav, kub hnyiab lossis tuag. Bromoacetates thiab chloroacetates yog qhov khaus heev / lachrymators. Cov tshuaj tiv thaiv nrog dej los yog huab cua noo yuav tso cov pa phem, corrosive lossis flammable gases. Cov tshuaj tiv thaiv nrog dej tuaj yeem ua kom muaj cua sov ntau uas yuav ua rau kom cov pa taws ntau ntxiv hauv huab cua. Hluav taws yuav ua rau khaus, corrosive thiab/los yog cov pa phem. Cov dej ntws los ntawm kev tswj hluav taws los yog cov dej dilution tuaj yeem ua rau corrosive thiab / los yog tshuaj lom thiab ua rau muaj kuab paug. |
| Hluav Taws Xob |
HIGHLY FLAMMABLE: Yuav tau yooj yim ignited los ntawm tshav kub, sparks los yog nplaim taws. Vapors tsim cov khoom sib xyaw nrog huab cua: sab hauv tsev, sab nraum zoov thiab cov kav dej phwj tuaj tawg. Feem ntau cov vapors hnyav dua li huab cua. Lawv yuav kis tau mus rau hauv av thiab sau rau hauv qhov chaw qis lossis qhov chaw kaw (sewers, hauv qab daus, tanks). Vapors tuaj yeem mus rau qhov chaw ntawm qhov hluav taws kub thiab rov qab flash. Cov tshuaj yuav hnov mob nrog dej (qee qhov hnyav) tso cov nplaim taws, muaj kuab lom lossis corrosive gases thiab ntws tawm. Kev sib cuag nrog cov hlau tuaj yeem hloov pauv cov pa hluav taws xob hydrogen. Cov thawv ntim khoom tuaj yeem tawg thaum cua sov lossis yog tias muaj dej paug. |
| Ntxim yuav nphav raug |
tert-Butyl isocyanate yog siv los ua reagent hauv cov organic synthesis; siv los ua intermediates hauv kev tsim tshuaj thiab lwm yam tshuaj |
| Kev xa khoom |
UN2484 tert-Butyl isocyanate, Hazard chav kawm: 6.1; Cov ntawv lo: 6.1-Txoj Kev Ncauj Ncauj Ncauj Ncauj Ncauj, 3-Flammable kua. Inhalation Hazard Zone A. PGI |
| Txoj Kev Purification |
Nws yog LACHRYMATORY thiab TOXIC, thiab yuav tsum muaj IR nrog 2251 (CN) cm-1 thiab tsis muaj OH bands. NMR yuav tsum muaj ib pawg ntawm 1.37 ppm los ntawm TMS. Purify nws los ntawm fractional distillation nyob rau hauv lub siab txo. [Greene & Bergmark J Org Chem 36 3056 1971, Curtius J Prakt Chem 125 152 1930, Beilstein 4 IV 669.] |
| Kev tsis sib haum xeeb |
Cov kua nplaum heev thiab vapor; tsim tawg sib xyaw nrog huab cua. Isocyanates yog cov flammable thiab reactive nrog ntau lub tebchaw, txawm nrog lawv tus kheej. Tsis sib haum nrog oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, thiab lwm yam); kev sib cuag tej zaum yuav ua rau hluav taws kub los yog tawg. Cov tshuaj tiv thaiv nrog cov huab cua ntub dej, dej los yog cawv yuav tsim amines thiab insoluble polyureas thiab react exothermically, tso tshuaj lom, corrosive los yog flammable gases, nrog rau cov pa roj carbon dioxide; thiab, tib lub sijhawm, yuav ua rau muaj kev tawm tsam hnyav ntawm cov cua sov ua kom cov pa taws hauv huab cua. Tsis sib haum nrog amines, aldehydes, alkali hlau, ammonia, carboxylic acids, caprolactum, alkaline cov ntaub ntawv, glycols, ketones, mercaptans, hydrides, organotin catalysts, phenols, muaj zog acids, muaj zog bases, muaj zog txo cov neeg ua haujlwm xws li hydrides, urees. Kev kub siab lossis kev sib cuag nrog cov kua qaub, cov hauv paus, tertiary amines, thiab acyl-chlorides tuaj yeem ua rau tawg polymerization. Tawm tsam qee yam yas, roj hmab thiab txheej txheej. Kev sib cuag nrog cov hlau tuaj yeem hloov pauv cov pa hluav taws xob hydrogen. Tej zaum yuav khaws cov nqi hluav taws xob zoo li qub, thiab tuaj yeem ua rau ignition ntawm nws cov vapors |

Pov tseg cov ntsiab lus thiab ntim rau hauv qhov chaw pov tseg pov tseg uas pom zoo. Siv cov kev pabcuam pov tseg pov tseg uas muaj ntawv tso cai los pov tseg cov khoom no. Ceeb toom: cov tshuaj no yog cov nplaim taws heev nrog lub teeb nyem tsawg heev (23.5 C). Dissolve los yog sib tov cov khoom nrog ib tug combustible solvent thiab hlawv nyob rau hauv ib tug chemical incinerator nruab nrog ib tug afterburner thiab scrubber. Tag nrho tsoom fwv teb chaws, xeev, thiab cheeb tsam ib puag ncig cov cai yuav tsum tau ua raws li. |
