    Khoom siv:

    1.Valeric anhydride feem ntau yog siv los ua reagent thiab nruab nrab hauv cov organic synthesis.

    2.Nws tuaj yeem siv los npaj cov tebchaw nrog ntau pawg ua haujlwm, xws li ethyl acetate, anhydride esters thiab amides.

    3.Valeric anhydride tuaj yeem siv rau hauv kev sib txuas ntawm cov tshuaj tua kab thiab tshuaj tsw qab.

    Cov ntaub ntawv kev nyab xeeb:

    1.Valeric anhydride yog irritating thiab corrosive, tsis txhob sib cuag nrog daim tawv nqaij thiab ob lub qhov muag thiab xyuas kom meej tias nws yog lis nyob rau hauv ib tug zoo-ventilated cheeb tsam.

    2.Thaum tuav thiab khaws cia, tsis txhob sib cuag nrog cov neeg ua haujlwm oxidising lossis cov kua qaub thiab cov hauv paus kom tsis txhob muaj kev phom sij txaus ntshai.

    3. Ua raws li cov txheej txheem tswj kev nyab xeeb rau cov tshuaj thaum lub sijhawm ua haujlwm thiab muaj cov cuab yeej tiv thaiv tsim nyog xws li kuaj cov hnab looj tes, tsom iav kev nyab xeeb, thiab lwm yam.
