Daim ntawv thov
1. Diethyl sulfate feem ntau yog siv los ua tus neeg sawv cev zoo ethylating hauv cov organic synthesis los qhia ethyl pawg rau hauv phenols, amines, thiab thiols los tsim cov dyes, pigments, pharmaceuticals, thiab tshuaj ua liaj ua teb.
2. Diethyl sulfate CAS 64-67-5 ua haujlwm tseem ceeb hauv kev tsim cov ntawv carbonless, textiles, thiab surfactants, thiab yog siv los ua ib qho chaw kuaj reagent thiab mutagen hauv kev tshawb nrhiav caj ces, xws li hauv kev tsim cov Luther ntau yam barley.
3. Daim ntawv thov ntawm Diethyl sulfate kuj suav nrog nws txoj kev siv hauv cov txheej txheem dej tsis ncaj rau cov khoom siv hluav taws xob ethanol thiab ua tus accelerator hauv qee cov txheej txheem sulfonation.
Cia thiab ceev faj
1. Khaws Diethyl sulfate nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv ib qho chaw txias, qhuav, thiab zoo- qhov cua, tiv thaiv los ntawm ya raws thiab cua sov; pom zoo cia yog nyob rau hauv ib tug txias, tsaus cheeb tsam hauv qab no 15 degree.
2. Khaws Diethyl sulfate nruj me ntsis kom deb ntawm cov khoom muaj zog oxidizing, muaj zog hauv paus, dej, thiab khoom noj khoom haus; nws reacts maj mam nrog dej los tsim corrosive sulfuric acid thiab yog incompatible nrog cov ntaub ntawv xws li alkali hlau.
3. Ib txwm Diethyl sulfate CAS 64-67-5 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj, hnav looj tsom iav kom nruj, thiab hnav khaub ncaws tiv thaiv; kov Diethyl sulfate nkaus xwb nyob rau hauv lub fume hood nrog cov khoom tawg-pov thawj kom tsis txhob nqus pa ntawm vapors.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav (tsawg kawg 50 meters), tshem tawm tag nrho cov qhov hluav taws xob, thiab muab qhov cua txaus; muaj Diethyl sulfate siv qhuav, inert, tsis yog - cov khoom siv hluav taws xob uas nqus tau (xws li cov xuab zeb qhuav) thiab TSIS TXHOB siv dej lossis cov khoom siv hluav taws xob.
2. Ua tib zoo sau Diethyl sulfate CAS 64-67-5 siv cov cuab yeej uas tsis muaj hluav taws xob rau hauv cov thawv ntim khoom uas muaj cov tshuaj tiv thaiv corrosion-resistant rau pov tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig; tiv thaiv kev nkag mus rau hauv qhov dej los yog txoj kev dej.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg tag nrho - cov cuab yeej tiv thaiv nrog rau tus kheej -cov cuab yeej ua pa (SCBA) thaum ntxuav; Diethyl sulfate yog cais rau kev thauj mus los (UN1594, Hazard Class 6.1, PG II).
Cov ntaub ntawv kev nyab xeeb
1. Diethyl sulfate yog cais raws li GHS Qeb 1B carcinogen thiab Qeb 1B mutagen (H340/H350, phom sij) thiab corrosive, ua rau tawv nqaij kub hnyiab thiab mob qhov muag (H314/H318); Nws yog qhov tuag taus yog tias nqus tau thiab muaj teeb meem yog tias nqos los yog sib cuag nrog daim tawv nqaij (H302+H312+H332).
2. Diethyl sulfate muaj NFPA kev ntsuam xyuas kev noj qab haus huv ntawm 3 (kev phom sij hnyav) thiab lub teeb nyem ntawm 104℃(219℃F); Nws yog combustible thiab nws cov thermal decomposition ua cov pa phem heev nrog rau cov sulfur oxides, thiab nws hydrolyzes nyob rau hauv lub xub ntiag ntawm noo noo los tsim sulfuric acid thiab ethanol.
3. Diethyl sulfate CAS 64-67-5 yog IARC Pawg 2A (tej zaum carcinogenic rau tib neeg) cov tshuaj lom neeg thiab muaj tshuaj lom rau cov dej hauv dej nrog cov teebmeem ntev (H402); ib txwm sab laj nrog Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDS) kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P303+P361+P353 rau daim tawv nqaij, P305+P351+P338 rau qhov muag, P301+P330+P331 rau kev noj), thiab yuav tsum tau tuav.
