Daim ntawv thov
1. Allyl chloroformate feem ntau yog siv los ua alkylating thiab tiv thaiv pab pawg reagent hauv cov organic synthesis, tshwj xeeb tshaj yog rau kev qhia txog pawg allyloxycarbonyl (Alloc) hauv peptide thiab carbohydrate chemistry.
2. Allyl chloroformate CAS 2937-50-0 ua haujlwm nruab nrab rau kev npaj cov carbonates, esters, thiab lwm yam kev ua haujlwm ntawm allyl compounds.
3. Cov tshuaj no kuj tseem siv hauv cov tshuaj polymer thiab ua cov tshuaj reagent hauv palladium-catalyzed deprotection cov tshuaj tiv thaiv.
Cia thiab ceev faj
1. Khaws allyl chloroformate nyob rau 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 Allyl chloroformate CAS 2937-50-0 lub thawv kaw kom nruj thiab sau meej 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. Ua tib zoo ceev faj siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE): tshuaj lom neeg -cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, daim npog ntsej muag, thiab cov kua qaub- cov tshuaj tiv thaiv lab lub tsho. 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 Allyl chloroformate CAS 2937-50-0 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. Allyl chloroformate yog ** corrosive heev, noo noo -sensitive, thiab ib tug lachrymator **. 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 cov hauv paus, tso cua sov thiab cov pa phem / corrosive gases (hydrogen chloride, allyl cawv, carbon dioxide).
2. Allyl chloroformate CAS 2937-50-0 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 allyl 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.
