Daim ntawv thov
1. Thiophene yog ib qho tseem ceeb heterocyclic compound thiab ntau lub tsev thaiv nyob rau hauv cov organic synthesis, siv los ua ib qho tsis yog -polar hnyav thiab ib qho tseem ceeb nruab nrab rau kev tsim dyes thiab kws tshuaj. Nws cov derivatives yog qhov tseem ceeb hauv cov khoom siv niaj hnub no los tsim cov organic semiconductors, nonlinear optics, hnub ci hlwb, thiab sensors.
2. Cov khoom siv ua haujlwm tseem ceeb hauv C4-lub tsev thaiv rau kev tsim cov nplhaib sib txuas uas pom muaj nyob rau hauv cov khoom siv roj ntsha thiab cov tshuaj siv tshuaj .Thiophene CAS 110-02-1 tuaj yeem ua rau muaj kev cuam tshuam zoo li dearomative cycloadditions los tsim cov benzenes hloov pauv, tseem ceeb rau kev tshawb nrhiav tshuaj thiab kev cog qoob loo.
3. Cov ntawv thov ntawm Thiophene kuj suav nrog nws qhov muaj nyob hauv cov metabolite hauv cov nroj tsuag thiab cov kab mob microbes, nws siv hauv cov tshuaj ua liaj ua teb nrog tshuaj tua kab, thiab ua tus precursor rau thiophene S-oxides thiab S,S-dioxides siv hauv cov tshuaj tiv thaiv cascade los tsim cov txheej txheem molecular complex.
Cia thiab ceev faj
1. Khaws Thiophene nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib tug inert gas (xws li, nitrogen) nyob rau hauv ib tug txias, qhuav, zoo- qhov cua qhov chaw, tiv thaiv los ntawm lub teeb thiab cua sov. Pom zoo cia yog nyob rau hauv qhov chaw txias thiab tsaus hauv qab 15 degree.
2. Khaws Thiophene kom nruj kom deb ntawm cov neeg muaj zog oxidizing (xws li cov concentrated nitric acid) thiab cov khoom siv hluav taws xob (kub kub, sparks, qhib nplaim taws), vim tias Thiophene CAS 110-02-1 yog cov nplaim hluav taws kub heev thiab ua rau muaj kev kub ntxhov nrog cov oxidizers, tsim kom muaj hluav taws kub thiab tawg.
3. Ib txwm siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov tshuaj lom neeg- cov hnab looj tes tiv thaiv (xws li roj hmab), tsom iav kev nyab xeeb nrog lub ntsej muag tiv thaiv, thiab tiv thaiv- khaub ncaws tiv thaiv zoo li qub; tsuas yog siv nrog tawg- cov khoom pov thawj thiab qhov cua txaus hauv lub hood fume.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav (tsawg kawg 50 meters / 150 ko taw nyob rau hauv tag nrho cov lus qhia) thiab tshem tawm tag nrho cov ignition qhov chaw. Rau cov dej nchuav loj, xav txog kev khiav tawm hauv nqes mus tsawg kawg 300 meters (1000 ko taw).
2. Muaj Thiophene siv cov khoom qhuav, tsis muaj zog, tsis yog-cov khoom siv hluav taws xob uas muaj hluav taws xob (xws li cov xuab zeb qhuav) thiab TSIS TXHOB kov lossis taug kev los ntawm cov khoom nchuav. Ua tib zoo sau cov khoom siv uas tsis yog- cov cuab yeej hluav taws xob rau hauv cov thawv ntim khoom pov tseg, sau cov tshuaj pov tseg kom raug raws li hauv zos, xeev, thiab tsoomfwv cov cai tswjfwm ib puag ncig.
3. Tus neeg ua haujlwm Thiophene CAS 110-02-1 yuav tsum hnav cov khoom siv tshuaj tiv thaiv tag nrho nrog rau qhov zoo ntawm tus kheej lub tshuab ua pa (SCBA) thaum ntxuav. Tiv thaiv kom tsis txhob nkag mus rau hauv cov dej ntws los yog hauv dej vim tias Thiophene muaj kev phom sij rau cov dej hauv dej. Thiophene yog cais rau kev thauj mus los (UN2414, Hazard Class 3, PG II).
Cov ntaub ntawv kev nyab xeeb
1. Thiophene yog cais nrog GHS teeb liab lo lus "Danger" thiab yog ib tug heev flammable kua thiab vapor (H225) nrog ib tug flash point li ntawm -9℃mus rau -1℃(16-30℃F). Thiophene CAS 110-02-1 ua rau tawv nqaij khaus (H315), khaus qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa.
2. Thiophene muaj teeb meem yog tias nqos tau (H302) thiab tuaj yeem ua rau lub cev puas tsuaj (lub siab, lub hlwb) los ntawm kev raug ncua ntev lossis rov ua dua (H373). Nws muaj kev phom sij rau cov tsiaj hauv dej nrog ntev - cov teebmeem ntev (H412). Cov vapors hnyav dua li huab cua (vapor ceev 2.9) thiab tuaj yeem tsim cov khoom tawg nrog cua (LEL 2.1%, UEL 17.25%). Thermal decomposition los yog combustion ua rau muaj kuab lom thiab irritating pa xws li carbon oxides thiab sulfur oxides.
3. Nco ntsoov sab laj txog Daim Ntawv Qhia Txog Kev Nyab Xeeb Tshwj Xeeb (SDS) rau Thiophene kom tiav cov ntaub ntawv txaus ntshai, ua ntej- txheej txheem pab (P305+P351+P338 rau qhov muag, P303+P361+P353 rau daim tawv nqaij, P301+P330+P331 rau kev noj, P331 rau kev noj, Phalation cov lus qhia. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib hluav taws), P233 (kom kaw lub thawv kom nruj), P240 (hauv av / daim ntawv cog lus), thiab P280 (coj hnab looj tes tiv thaiv / qhov muag tiv thaiv).
