Potassium thioacetate CAS 10387-40-3 kuj tseem siv rau hauv biochemistry rau kev soj ntsuam enzyme, hauv analytical chemistry rau kev kuaj pom hlau, thiab hauv kev tshawb fawb ib puag ncig rau kev kho hlau hnyav.

1. Khaws Potassium thioacetate rau hauv lub thawv kaw nruj nreem nyob rau hauv ib qho roj inert (xws li, argon) nyob rau hauv ib qho chaw txias, qhuav, thiab zoo- qhov cua, vim nws yog huab cua- rhiab heev thiab hygroscopic . Pom zoo cia kub sib txawv; nws tuaj yeem khaws cia ntawm chav sov (RT), ntawm qhov kub thiab txias hauv qab argon, lossis ntawm -20℃rau kev ruaj ntseg ntawm cov hmoov mus ntev.
2. Khaws cov Potassium thioacetate nruj me ntsis kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm, muaj zog acids, thiab muaj zog alkalis, vim cov no tsis sib xws thiab yuav ua rau muaj kev phom sij. Potassium thioacetate CAS 10387-40-3 kuj yuav tsum tau tiv thaiv los ntawm lub teeb thiab noo noo.
3. Ib txwm siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv (xws li roj hmab), nruj nruj tsom iav kev nyab xeeb nrog sab- cov ntaub thaiv npog, thiab cov khaub ncaws tiv thaiv tsis zoo thaum tuav cov Potassium thioacetate tiv thaiv tawv nqaij, qhov muag, thiab ua pa. Tsuas yog siv cov cua kom txaus, tsis txhob muaj plua plav, thiab ntxuav kom huv si tom qab tuav.

1. Tam sim ntawd cais qhov chaw nchuav, siv tag nrho cov khoom tiv thaiv tus kheej nrog rau tus kheej -cov cuab yeej ua pa (SCBA), thiab xyuas kom muaj cua txaus. Tshem tawm txhua qhov hluav taws kub thiab tsis txhob cia Potassium thioacetate nkag mus rau hauv cov dej ntws los yog cov dej.
2. Muaj cov Potassium thioacetate siv inert, tsis yog -cov khoom siv hluav taws xob nqus tau (xws li, lub ntiaj teb diatomaceous, universal binders, xuab zeb qhuav). Rau cov nchuav qhuav, ua tib zoo cheb siv cov cuab yeej uas tsis yog-tua hluav taws xob thiab tso Potassium thioacetate CAS 10387-40-3 rau hauv lub thawv ntim khoom, uas muaj cov tshuaj khib nyiab. Rau cov kua nchuav, nqus cov tshuaj nrog cov khoom siv khi.
3. Decontaminate qhov chaw thiab khoom siv los ntawm kev txhuam nrog cawv. Pov tseg tag nrho cov khoom tsis huv raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig. Nyob rau hauv cov xwm txheej hluav taws kub, cov khoom tawg muaj xws li cov pa roj carbon monoxide, carbon dioxide, thiab nitrogen oxides. Potassium thioacetate yog cais rau kev thauj los ntawm qee qhov chaw raws li UN3335 (Hazard Class 9, PG III), tab sis lwm qhov chaw suav tias tsis yog - phom sij rau kev thauj mus los.

1. Potassium thioacetate yog cais nrog GHS teeb liab lo lus "Ceeb toom". Nws ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab tej zaum yuav ua rau mob ua pa (H335). Qee qhov chaw kuj tau faib cov Potassium thioacetate CAS 10387-40-3 ua teeb meem yog tias nqos tau (H302) thiab muaj tshuaj lom heev rau cov dej hauv dej nrog cov teebmeem ntev (H410).
2. Potassium thioacetate muaj lub melting point uas txawv nyob rau hauv cov ntaub ntawv, xws li ntawm 173-176℃mus rau kwv yees li 240℃(decomposition) los yog 251-256 degree. Potassium thioacetate CAS 10387-40-3 muaj cov ntxhiab tsw txawv, yog soluble hauv dej, methanol, thiab qee qhov polar solvents, tab sis insoluble nyob rau hauv alkanes, ethers, thiab feem ntau nonpolar solvents. Thermal decomposition ua rau cov pa phem xws li carbon monoxide, carbon dioxide, thiab hydrogen sulfide.
3. Nco ntsoov sab laj nrog Daim Ntawv Qhia Txog Kev Nyab Xeeb tshwj xeeb (SDS) rau Potassium thioacetate kom tiav cov ntaub ntawv txaus ntshai, ua ntej- cov txheej txheem pab (P305+P351+P338 rau qhov muag, P302+P352 rau daim tawv nqaij, P304+P340 rau kev nqus pa, P{1.2} cov lus qhia txog kev tuav tes Cov lus ceeb toom muaj xws li P261 (tsis txhob ua pa plua plav), P264 (ntxuav daim tawv nqaij kom huv si tom qab tuav), P273 (tsis txhob tso rau ib puag ncig), thiab P280 (hnav hnab looj tes tiv thaiv / qhov muag tiv thaiv).
