Daim ntawv thov
1. Chloromethyl pivalate feem ntau yog siv los ua ntau yam intermediate hauv cov organic synthesis rau kev tsim tshuaj thiab agrochemicals. Nws cov reactivity siab stems los ntawm pawg chloromethyl, uas nkag mus rau hauv nucleophilic hloov cov tshuaj tiv thaiv.
2. Chloromethyl pivalate CAS 18997-19-8 yog tshwj xeeb muaj nuj nqis rau kev qhia cov pivaloyloxymethyl (POM) pab pawg, uas ua hauj lwm pab raws li ib tug tiv thaiv pab pawg neeg rau amino functions los yog raws li ib tug prodrug moiety los txhim kho lub bioavailability thiab stability ntawm active tshuaj cov khoom xyaw (APIs). Nws yog ib qho tseem ceeb ua hauj lwm nyob rau hauv lub synthesis ntawm antiviral tshuaj xws li adefovir dipivoxil.
3. Cov ntawv thov ntawm Chloromethyl pivalate kuj suav nrog nws siv hauv kev sib txuas ntawm oxazolines thiab ua lub tsev thaiv kev tsim cov tshuaj tiv thaiv qoob loo zoo xws li tshuaj tua kab thiab tshuaj tua kab.
Cia thiab ceev faj
1. Khaws Chloromethyl pivalate nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib tug inert gas (xws li, nitrogen los yog argon) nyob rau hauv ib tug txias, qhuav, thiab zoo - qhov cua. Nws yog ib qho tseem ceeb kom khaws Chloromethyl pivalate CAS 18997-19-8 kom deb ntawm tshav kub, sparks, thiab qhib nplaim taws. Pom zoo cia yog nyob rau hauv ib qho chaw txias thiab tsaus, qhov zoo tshaj plaws hauv qab 15 degree.
2. Khaws Chloromethyl pivalate nruj me ntsis kom deb ntawm cov muaj zog oxidizing cov neeg ua hauj, vim nws yog incompatible. Nws yog noo noo-sensitive thiab yuav tsum tau tiv thaiv los ntawm dej ingress. Siv cov cuab yeej uas tsis yog- ua kom muaj hluav taws xob thiab xyuas kom muaj kev sib txuas hauv av / kev sib txuas ntawm cov ntim khoom thiab txais cov khoom siv los tiv thaiv qhov paug tawm.
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 (tsis pom kev), hnav tsom iav kom nruj, tiv thaiv lub ntsej muag, thiab hnav khaub ncaws tiv thaiv. Tsuas yog siv cov cua kom txaus los yog hauv cov fume hood, thiab tsis txhob ua pa pa, pos huab, lossis roj.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav, tshem tawm tag nrho cov qhov hluav taws xob, thiab muab qhov cua txaus. Muaj chloromethyl pivalate siv inert, tsis yog - cov khoom siv hluav taws xob nqus tau (piv txwv li, xuab zeb qhuav) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws lossis cov dej.
2. Ua tib zoo sau Chloromethyl pivalate CAS 18997-19-8 siv cov cuab yeej pov thawj los yog lub tshuab nqus tsev tawg rau hauv lub thawv ntim tshuaj khib nyiab pov tseg kom raug raws li kev cai hauv zos, xeev, thiab tseem fwv ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tus kheej -cov cuab yeej ua pa (SCBA) yog tias tsim nyog thaum ntxuav. Chloromethyl pivalate yog cais rau kev thauj mus los (UN2924 lossis UN3272, Hazard Class 3/8, Packing Group III).
Cov ntaub ntawv kev nyab xeeb
1. Chloromethyl pivalate yog cais raws li cov kua flammable thiab vapor (H226) nrog GHS teeb liab lo lus "Danger". Nws ua rau cov tawv nqaij kub hnyiab thiab qhov muag puas tsuaj loj (H314), thiab muaj kev phom sij yog tias nqos, nqus tau, lossis kov ntawm daim tawv nqaij (H302+H312+H332).
2. Chloromethyl pivalate kuj ua rau tawv nqaij khaus (H315) thiab khaus qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335). Nws cov thermal decomposition ua rau cov pa roj carbon monoxide, carbon dioxide, thiab hydrogen chloride gas.
3. Ib txwm Chloromethyl pivalate CAS 18997-19-8 sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Chloromethyl pivalate kom tiav cov ntaub ntawv txaus ntshai, ua ntej- txheej txheem pab (P301+P330+P331 rau kev noj, P3}, P{3} P305+P351+P338+P310 rau qhov muag, P304+P340+P310 rau kev nqus pa), thiab cov lus qhia tuav. Cov lus qhia ceev faj muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib nplaim taws), P233 ( khaws lub thawv kaw kom nruj), P240 (hauv av / daim ntawv cog lus), P241 (siv cov khoom pov thawj tawg), P242 (siv cov cuab yeej tsis muaj teeb ci), P243 (noj ceev faj tiv thaiv kom tsis txhob muaj 60 vau tawm), P243 (tsis ua pa tawm ntawm daim tawv nqaij), P243. kom huv si tom qab tuav), thiab P280 (hnav looj hnab looj tes tiv thaiv qhov muag).
