Daim ntawv thov
1. L-Valinol feem ntau yog siv los ua chiral tsev thaiv thiab daws tus neeg sawv cev hauv asymmetric synthesis ntawm cov kws tshuaj, xws li tshuaj tiv thaiv kab mob thiab tshuaj tiv thaiv.
2. L-valinol CAS 2026-48-4 yog lub luag haujlwm tseem ceeb hauv kev tsim cov chiral ligands, catalysts, thiab lwm yam tshuaj zoo.
3. Cov compound no kuj yog siv rau hauv kev tshawb fawb biochemical thiab ua tus thawj coj rau cov amino acid derivatives tsis zoo.
Cia thiab ceev faj
1. Khaws L-valinol nyob rau hauv qhov chaw txias, qhuav, zoo- qhov cua, nyob rau hauv ib qho chaw inert yog ua tau, thiab kom deb ntawm tshav kub thiab ignition qhov chaw.
2. Khaws L-valinol CAS 2026-48-4 lub thawv kaw kom nruj thiab muaj cov ntawv cim meej. Sib cais los ntawm cov tshuaj muaj zog oxidizing, muaj zog acids, thiab acid chlorides.
3. Kov nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog tshuaj lom neeg - hnab looj tes tiv thaiv, tsom iav tiv thaiv, thiab lub tsho tiv no. Siv lub fume hood kom tsis txhob nqus cov pa thiab cov tawv nqaij.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, ua kom qhov cua, thiab hnav cov khoom tiv thaiv tsim nyog (cov hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa yog tias vapors tseem ceeb).
2. Absorb L-valinol CAS 2026-48-4 spill nrog ib qho inert, tsis-combustible khoom (xws li, xuab zeb, vermiculite). Muab cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom pov tseg uas raug kaw.
3. Tiv thaiv qhov sib xyaw kom tsis txhob nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Ntxuav qhov chaw cuam tshuam nrog dej thiab xab npum, ua raws li cov cai hauv zos.
Cov ntaub ntawv kev nyab xeeb
1. L-Valinol muaj teeb meem yog tias nqos, nqus tau, lossis tiv nrog daim tawv nqaij. Nws ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab tej zaum yuav ua rau ua pa ua pa. Nws yog ib qho amino cawv thiab yuav tsum tau kho raws li kev phom sij rau kev noj qab haus huv.
2. L-valinol CAS 2026-48-4 yog nplaim taws thiab nws cov vapors tuaj yeem tsim cov khoom tawg nrog cua.
3. Nco ntsoov sab laj nrog tus nom L-valinol Safety Data Sheet (SDS) kom paub txog kev phom sij, tuav, thiab cov ntaub ntawv tswj hwm. Kov nrog ceev faj vim nws corrosivity thiab flammability.
