Daim ntawv thov
1. Ethyl glyoxylate yog dav siv los ua ib qho nruab nrab hauv kev sib txuas ntawm cov kws tshuaj vim muaj qhov ua haujlwm siab ntawm nws cov aldehyde muaj nuj nqi. Nws yog koom nrog hauv kev sib txuas ntawm ntau yam tshuaj sib tw, suav nrog cov tshuaj tua kab mob thiab tshuaj tiv thaiv - cov khoom inflammatory .
2. Ethyl glyoxylate CAS 924-44-7 yog lub tsev tseem ceeb hauv cov organic synthesis rau cov tshuaj tiv thaiv zoo li Friedel-Crafts alkylations nrog thiophenes thiab aromatic amines los tsim cov cawv theem nrab thiab lwm cov molecules complex .
3. Cov ntawv thov ntawm Ethyl glyoxylate kuj suav nrog nws siv hauv kev tsim cov biodegradable polymer, poly (ethyl glyoxylate), thiab ua ntau yam reagent hauv enantioselective catalysis rau tsim chiral kws tshuaj intermediates.
Cia thiab ceev faj
1. Khaws Ethyl glyoxylate rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib qho chaw inert (xws li, nitrogen los yog argon) nyob rau hauv ib qho chaw txias, qhuav, thiab zoo- qhov cua, tiv thaiv los ntawm lub teeb thiab huab cua vim nws huab cua- rhiab qhov xwm. Qhov chaw txias, tsaus yog qhov tseem ceeb rau kev ruaj ntseg.
2. Khaws Ethyl glyoxylate kom deb ntawm tshav kub, sparks, qhib nplaim taws, thiab cov ntaub ntawv incompatible xws li muaj zog oxidizing neeg sawv cev thiab muaj zog puag. 50% tov nyob rau hauv toluene yog heev flammable nrog ib tug flash point ntawm 7℃(44℃F).
3. Ib txwm Ethyl glyoxylate CAS 924-44-7 siv cov khoom tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav, thiab khaub ncaws tiv thaiv, thaum tuav Ethyl glyoxylate. Siv tsuas yog nyob rau hauv cov tshuaj fume hood kom tsis txhob nqus pa.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd khiav tawm ntawm thaj chaw, tshem tawm tag nrho cov khoom siv hluav taws xob, thiab muaj cov Ethyl glyoxylate spill siv inert, tsis yog -cov khoom siv hluav taws xob (xws li, xuab zeb, vermiculite). Tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog txoj kev dej.
2. Ua tib zoo sau Ethyl glyoxylate CAS 924-44-7 mus rau hauv lub kaw lus kaw, sau cov tshuaj khib nyiab pov tseg kom raug raws li cov cai hauv zos, xeev, thiab tseem fwv ib puag ncig. Rau 50% tshuaj nyob rau hauv toluene, qhov no yog cais raws li ib tug flammable kua (UN1993).
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; muab qhov cua txaus thiab pov tseg tag nrho cov khoom pov tseg raws li cov khoom siv phom sij.
Cov ntaub ntawv kev nyab xeeb
1. Ethyl glyoxylate (feem ntau raws li 50% tshuaj nyob rau hauv toluene) yog cais raws li ib tug heev flammable kua thiab vapor (H225). Nws muaj kev phom sij yog tias nqos tau (tej zaum yuav ua rau tuag taus yog tias nqos thiab nkag mus rau hauv txoj hlab pa - H304), ua rau tawv nqaij khaus (H315), thiab tuaj yeem ua rau qaug zog lossis kiv taub hau (H336).
2. Ethyl glyoxylate yog xav tias ua rau muaj kev puas tsuaj rau kev xeeb tub lossis tus menyuam hauv plab (H361) thiab yuav ua rau lub cev puas tsuaj los ntawm kev raug ncua ntev lossis rov ua dua (H373). Nws cov thermal decomposition tuaj yeem tsim cov pa phem, suav nrog carbon monoxide.
3. Ib txwm Ethyl glyoxylate CAS 924-44-7 sab laj rau Daim Ntawv Qhia Kev Nyab Xeeb tshwj xeeb (SDS) rau Ethyl glyoxylate kom paub cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P301+P310 rau kev noj, P303+P361+P353 rau daim tawv nqaij), thiab cov lus qhia tuav. Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib nplaim taws) thiab P280 (hnav looj hnab looj tes / tiv thaiv qhov muag).
