Daim ntawv thov
1. Valeric anhydride feem ntau yog siv los ua tus neeg sawv cev acylating hauv cov organic synthesis, tshwj xeeb tshaj yog rau kev qhia txog valeryl (pentanoyl) pawg.
2. Valeric anhydride CAS 2082-59-9 ua cov tshuaj reagent hauv kev tsim tshuaj, tshuaj tsw qab, tsw, thiab cov yas yas.
3. Valeric anhydride yog ua hauj lwm nyob rau hauv polymer chemistry raws li ib tug modifier thiab nyob rau hauv lub synthesis ntawm tshwj xeeb esters thiab amides.
Cia thiab ceev faj
1. Store Valeric anhydride in a tightly sealed, moisture-proof container in a cool, dry, well-ventilated area away from heat and incompatible materials.
2. Khaws Valeric anhydride CAS 2082-59-9 kom deb ntawm dej, cawv, muaj zog hauv paus, oxidizing tus neeg sawv cev, thiab amines los tiv thaiv kev kub ntxhov exothermic.
3. Kov Valeric anhydride nrog kev saib xyuas hnyav kom tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab khaub ncaws; nws yog corrosive thiab reacts vigorously nrog noo noo.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw, xyuas kom muaj cua, thiab hnav cov khoom tiv thaiv tsim nyog (lub tshuab ua pa, hnab looj tes, tsom iav). Tsis txhob sib cuag nrog dej.
2. Muaj CAS 2082-59-9 qhov nchuav nrog cov xuab zeb qhuav los yog lwm yam uas tsis yog-combustible absorbent. Sau cov khoom pov tseg rau hauv ib lub thawv ntim khoom ntim rau corrosive txaus ntshai pov tseg.
3. Ua tib zoo saib xyuas cov khoom seem nrog cov tshuaj dilute alkaline (xws li sodium carbonate) thiab ntxuav kom huv si. Pov tseg cov pov tseg raws li kev cai pov tseg pov tseg. Tiv thaiv kev nkag mus rau hauv cov dej ntws.
Cov ntaub ntawv kev nyab xeeb
1. Valeric anhydride ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa ua pa. Nws muaj teeb meem yog tias nqos los yog nqus tau.
2. Valeric anhydride CAS 2082-59-9 reacts hnyav nrog dej, tso corrosive thiab flammable vapors (valeric acid). Nws yog flammable thiab tshuaj lom rau lub neej hauv dej.
3. Hnav cov cuab yeej tiv thaiv tag nrho (acid-cov hnab looj tes tiv thaiv, tsom iav, daim npog ntsej muag, lub tsho hauv qab) thiab ua haujlwm hauv lub hood fume. Nrog rau Daim Ntawv Qhia Kev Nyab Xeeb ua ntej siv.
