Daim ntawv thov
1. 4′-Hydroxyvalerophenone feem ntau yog siv los ua ib qho nruab nrab ntawm cov organic synthesis, tshwj xeeb tshaj yog rau kev tsim tshuaj thiab agrochemicals.
2. 4′-Hydroxyvalerophenone CAS 2589-71-1 ua lub tsev tseem ceeb rau kev sib txuas ntawm ntau cov ketones, chalcones, thiab lwm yam tshuaj zoo.
3. Qhov sib xyaw no kuj tseem siv rau hauv kev tshawb fawb los tsim cov ntaub ntawv tshiab thiab ua tus thawj coj rau cov tshuaj tsw qab lossis cov khoom tshwj xeeb polymers.
Cia thiab ceev faj
1. Khaws 4′-hydroxyvalerophenone nyob rau hauv qhov chaw txias, qhuav, zoo- qhov cua, tiv thaiv los ntawm lub teeb thiab deb ntawm tshav kub thiab qhov hluav taws kub.
2. Khaws lub thawv kaw kom nruj thiab sib cais los ntawm cov khoom muaj zog oxidizing, muaj zog hauv paus, thiab cov kua qaub chlorides / anhydrides.
3. Kov 4′-Hydroxyvalerophenone CAS 2589-71-1 nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), suav nrog cov hnab looj tes tiv thaiv tshuaj, tsom iav kev nyab xeeb, thiab lub tsho tiv no. Siv lub fume hood kom tsis txhob nqus cov plua plav lossis vapors.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, xyuas kom muaj cua, thiab hnav cov khoom tiv thaiv tsim nyog ( hnab looj tes, tsom iav, khaub ncaws tiv thaiv).
2. Sau 4′-Hydroxyvalerophenone CAS 2589-71-1 nchuav nrog lub cuab yeej huv. Rau cov khoom ua kua / melted, nqus nrog inert absorbent (xws li, xuab zeb, vermiculite). Muab tag nrho cov khoom tsis huv tso rau hauv lub thawv ntim khoom pov tseg uas raug kaw.
3. Tiv thaiv qhov sib xyaw kom tsis txhob nkag mus rau hauv qhov dej los yog ib puag ncig. Ntxuav qhov chaw cuam tshuam kom huv si nrog cov kuab tshuaj uas tsim nyog los yog tshuaj ntxuav tes, ua raws li cov cai hauv zos.
Cov ntaub ntawv kev nyab xeeb
1. 4′-Hydroxyvalerophenone tuaj yeem ua rau muaj kev phom sij yog tias nqos, nqus tau, lossis kov ntawm daim tawv nqaij, thiab tuaj yeem ua rau tawv nqaij thiab qhov muag.
2. 4′-Hydroxyvalerophenone CAS 2589-71-1 yog combustible thiab nws vapors tuaj yeem tsim tawg sib xyaw nrog huab cua.
3. Nco ntsoov sab laj nrog nom tswv 4′-hydroxyvalerophenone Safety Data Sheet (SDS) kom paub txog kev phom sij, kev tuav pov hwm, thiab cov ntaub ntawv tswj hwm.
