Daim ntawv thov
1. Isovaleric acid feem ntau yog siv los ua ib qho tsw thiab tsw qab, imparting cheesy, sweaty, los yog rancid sau ntawv ntawm siab concentrations, tab sis pab rau fruity thiab creamy nuances nyob rau hauv ib tug kab.
2. Isovaleric acid CAS 503-74-2 ua haujlwm nruab nrab hauv kev sib txuas ntawm cov tshuaj, agrochemicals, plasticizers, thiab perfumes.
3. Cov tshuaj no kuj tseem siv rau hauv cov organic synthesis thiab ua tus thawj coj rau esters siv hauv cov khoom noj khoom haus thiab cov kuab tshuaj.
Cia thiab ceev faj
1. Khaws isovaleric acid nyob rau hauv ib qho chaw txias, qhuav, zoo- qhov chaw cua, kom deb ntawm cov cua sov thiab cov ntaub ntawv tsis sib xws xws li cov tshuaj muaj zog oxidizing thiab cov hauv paus.
2. Khaws lub thawv kaw kom nruj thiab nyob rau hauv ib lub thawv thib ob kom muaj cov xau thiab tswj nws cov ntxhiab tsw muaj zog.
3. Kov Isovaleric acid CAS 503-74-2 nrog cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), nrog rau cov hnab looj tes, tsom iav kev nyab xeeb, thiab lub tsho tiv no. Siv lub fume hood kom tsis txhob nqus pa.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm qhov chaw nchuav thiab hnav cov khoom tiv thaiv tsim nyog (cov hnab looj tes, tsom iav kev nyab xeeb, lub tshuab ua pa rau cov ntxhiab tsw).
2. Muaj Isovaleric acid CAS 503-74-2 nrog cov khoom nqus dej (piv txwv li, xuab zeb, vermiculite). Rau cov khoom, sib sau nrog cov cuab yeej huv. Muab cov khib nyiab tso rau hauv lub thawv tsim nyog rau kev pov tseg.
3. Tiv thaiv cov khoom los ntawm kev nkag mus rau hauv qhov dej los yog ib puag ncig. Neutralize residues nrog lub hauv paus me me (piv txwv li, sodium bicarbonate) thiab ntxuav thaj chaw nrog dej thiab xab npum. Ventilate kom huv si.
Cov ntaub ntawv kev nyab xeeb
1. Isovaleric acid ua rau tawv nqaij kub hnyiab heev, qhov muag puas, thiab muaj teeb meem yog tias nqos los yog nqus tau pa. Nws muaj zog heev, tsis kaj siab tsw.
2. Isovaleric acid CAS 503-74-2 yog combustible thiab tej zaum yuav emit irritating los yog lom fumes thaum rhuab mus decomposition.
3. Nco ntsoov sab laj nrog daim ntawv pov thawj isovaleric acid Safety Data Sheet (SDS) kom paub txog kev phom sij, tuav, thiab cov ntaub ntawv tswj hwm.
