Kev siv 2:Malonic acidsiv raws li ib tug complexing neeg sawv cev thiab kuj nyob rau hauv kev npaj ntawm barbiturate ntsev
Kev siv 3:Malonic acidyog ib qho nruab nrab ntawm cov fungicide Daowenling, thiab tseem yog ib qho nruab nrab ntawm cov nroj tsuag kev loj hlob regulator indomethacin.
Kev siv 4:Malonic acidthiab nws cov esters feem ntau yog siv rau hauv cov txuj lom, nplaum, resin additives, tshuaj intermediates, electroplating polishing agents, explosion control agents, kub welding flux additives, thiab lwm yam.
Siv 5: Hauv kev lag luam kws tshuaj,Malonic acid CAS 141-82-2yog siv los tsim Rumina, Barbital, Vitamin B1, Vitamin B2, Vitamin B6, Phenyl Phenylbutazone, Amino Acids, thiab lwm yam.
Kev siv 6:Malonic acidyog siv los ua tus neeg sawv cev kho mob ntawm txhuas. Vim tias tsuas yog dej thiab carbon dioxide yog tsim thaum lub sij hawm cua sov thiab decomposition, tsis muaj teeb meem ua paug.
Hauv qhov no, nws muaj txiaj ntsig zoo piv rau cov kua qaub raws li kev kho mob xws li formic acid siv yav dhau los.
Kev cia khoom
1. Ntim thiab khaws cia.
2. Siv cov hnab woven lined nrog cov hnab yas rau ntim, nrog rau qhov hnyav ntawm 25kg. Khaws thiab thauj khoom raws li kev cai lij choj tshuaj.
Kev ruaj ntseg
1. ruaj khov ntawm chav tsev kub thiab siab.
Txwv tsis pub: alkali, oxidant, txo tus neeg sawv cev.
2. Tsawg toxicity. Nws muaj kev cuam tshuam rau ntawm daim tawv nqaij thiab cov mucous membranes, tab sis tsis hnyav li oxalic acid. Qhov ncauj LD50 rau nas yog 1.54g / kg. Feem ntau, tsis muaj kev tiv thaiv tshwj xeeb rau kev tsim cov Malonic acid, tab sis cyanoacetic acid thiab Sodium cyanide yog ob qho tib si tshuaj lom. Yog li ntawd, yuav tsum tau saib xyuas tshwj xeeb thaum tuav cov khoom sib xyaw uas muaj cyano pawg. Cov cuab yeej tiv thaiv tshuaj lom yuav tsum tau hnav thiab kev ntsuas kev nyab xeeb yuav tsum tau tsim.
Kev pab thawj zaug
Tiv tauj daim tawv nqaij:Tshem cov khaub ncaws tsis huv thiab yaug nrog dej ntws. Yog tias muaj qhov kub hnyiab, kho lawv li cov kua qaub hlawv.
Qhov muag tiv tauj:Tam sim ntawd qhib daim tawv muag sab sauv thiab sab qis thiab yaug nrog dej ntws rau 15 feeb. Nrhiav kev kho mob.
Inhalation:Tshem tawm sai sai ntawm qhov chaw mus rau qhov chaw uas muaj huab cua ntshiab. Muab cov pa oxygen thaum ua pa nyuaj. Thaum ua tsis taus pa, tam sim ntawd ua pa ua pa. Nrhiav kev kho mob.
Noj:Cov uas ua yuam kev yuav tsum haus mis nyuj lossis qe dawb. Nrhiav kev kho mob.
