Cia thiab ceev faj
1. BOC-L-Valine yuav tsum tau muab khaws cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua qhov chaw ntawm 2-8℃.
2. BOC-L-Valine CAS 13734-41-3 yuav tsum muaj kev tiv thaiv los ntawm lub teeb, noo noo, thiab cov ntaub ntawv tsis sib xws xws li cov tshuaj muaj zog oxidizing thiab muaj zog acids / bases .
3. Cov neeg ua haujlwm yuav tsum hnav tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav tiv thaiv, thiab khaub ncaws tiv thaiv thaum tuav BOC-L-Valine .
4. Tsis txhob nqus cov hmoov av thiab tiv thaiv kev sib cuag ntawm daim tawv nqaij, qhov muag, thiab khaub ncaws thaum ua haujlwm nrog cov khoom no.
Kev kub ceev teb rau cov dej xau
1. Cais qhov chaw nchuav thiab tso pa tawm tam sim ntawd thaum BOC-L-Valine raug tso tawm.
2. Sau BOC-L-Valine CAS 13734-41-3 siv cov cuab yeej huv si thiab muab tso rau hauv lub thawv tsim nyog rau kev pov tseg lossis rov qab.
3. Tsis txhob tsim cov huab cua thaum cheb BOC-L-Valine hmoov kom txo tau cov pa paug.
4. Ntxuav qhov chaw raug mob kom huv si nrog dej tom qab tshem tawm tag nrho cov kab pom ntawm qhov sib xyaw.
Kev tiv thaiv hluav taws
1. BOC-L-Valine tsis raug cais raws li cov nplaim taws heev tab sis tuaj yeem decompose nyob rau hauv cov cua kub kub.
2. Siv cov tshuaj qhuav qhuav, cov pa roj carbon dioxide, lossis cov tshuaj tsuag dej los tua hluav taws uas cuam tshuam nrog cov khoom.
3. Cov neeg tua hluav taws BOC-L-Valine CAS 13734-41-3 yuav tsum hnav nws tus kheej- muaj lub tshuab ua pa thaum tuav cov BOC-L-Valine vim muaj cov pa phem decomposition.
4. Cov khoom puas tsuaj uas tsim nyob rau hauv hluav taws kub muaj xws li carbon oxides thiab nitrogen oxides (NOx).
