Daim ntawv thov
1. Butyl chloroformate feem ntau yog siv los ua alkylating thiab tiv thaiv pab pawg reagent hauv cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv peptide synthesis thiab kev tsim tshuaj.
2. Butyl chloroformate CAS 99-24-1 ua haujlwm nruab nrab rau kev qhia cov pab pawg butyloxycarbonyl (Boc) lossis tsim cov carbonate sib xyaw thiab esters.
3. Cov compound no kuj yog siv rau hauv polymer chemistry thiab ua tus neeg sawv cev derivatizing hauv analytical chemistry.
Cia thiab ceev faj
1. Khaws cov tshuaj butyl chloroformate hauv qhov txias, qhuav, zoo- qhov chaw cua, kom deb ntawm tshav kub, noo noo, thiab cov ntaub ntawv tsis sib xws (dej, cawv, hauv paus, oxidizing agents). Siv cov thawv airtight nyob rau hauv ib qho chaw inert yog tias ua tau.
2. Khaws lub thawv ntim kom nruj thiab sau kom meej. Kov thiab qhib cov thawv tsuas yog nyob rau hauv ib puag ncig qhuav (xws li, hnab looj tes lossis siv cov txheej txheem qhuav) txhawm rau tiv thaiv hydrolysis hnyav.
3. Kov Butyl chloroformate CAS 99-24-1 nrog ceev faj heev siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE): hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, daim npog ntsej muag, thiab lub tsho tiv thaiv cov kua qaub. Txhua zaus siv lub fume hood.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm tam sim ntawd thiab cais thaj chaw. Xyuas kom qhov cua thiab hnav cov iav tiv thaiv tag nrho (cov hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa haum rau cov kua qaub vapors).
2. **Tsis txhob siv dej.** Ua tib zoo npog Butyl chloroformate CAS 99-24-1 lossis muaj cov nchuav nrog cov khoom siv tsis zoo, qhuav nqus (xws li xuab zeb, vermiculite). Muab tag nrho cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom kaw, sau tias muaj kev phom sij.
3. Tiv thaiv qhov sib xyaw kom tsis txhob nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Decontaminate cov cuab yeej thiab qhov chaw nrog cov khoom qhuav qhuav ua ntej, tom qab ntawd ua tib zoo ntxuav nrog cov dej tsis huv yog tias tsim nyog. Nrhiav kev pab kws tshaj lij.
Cov ntaub ntawv kev nyab xeeb
1. Butyl chloroformate yog ** corrosive heev thiab noo noo -sensitive **. Nws ua rau tawv nqaij kub hnyiab heev, qhov muag puas, thiab ua pa puas. Nws muaj teeb meem yog tias nqos los yog nqus tau. Reacts hnyav nrog dej, cawv, thiab hauv paus, tso cua sov thiab tshuaj lom / corrosive gases (hydrogen chloride, butanol, carbon dioxide).
2. Butyl chloroformate CAS 99-24-1 yog flammable thiab tej zaum yuav emit toxic fumes (hydrogen chloride, phosgene, carbon oxides) thaum rhuab mus decomposition.
3. Nco ntsoov sab laj nrog daim ntawv pov thawj kev nyab xeeb ntawm butyl chloroformate Safety Data Sheet (SDS) thiab ua raws li kev noj qab haus huv hnyav, corrosion, thiab muaj kev phom sij. Yuav tsum muaj kev cob qhia tshwj xeeb thiab cov txheej txheem rau chloroformates.
