Taw qhia
Ethyl thioacetate hmoov. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm ethyl thioacetate:
Zoo:
Ethyl thioacetate yog cov kua tsis muaj xim nrog ib qho tshwj xeeb tsw tsw thiab qaub saj. Nws yog volatile ntawm chav tsev kub thiab muaj qhov ceev ntawm 0.979 g / mL. Ethyl thioacetate yog soluble hauv ntau cov kuab tshuaj organic xws li ethers, ethanol, thiab esters. Nws yog ib qho khoom siv hluav taws xob uas tsim cov roj sulfur dioxide thaum raug tshav kub los yog thaum raug hluav taws kub.
Siv:
Ethyl thioacetate feem ntau yog siv los ua cov tshuaj ua ntej rau glyphosate. Glyphosate yog ib qho tshuaj tua kab organophosphate dav siv hauv tshuaj tua kab mob, thiab ethyl thioacetate yuav tsum tau ua ib qho tseem ceeb nruab nrab hauv nws qhov kev npaj.
Txoj kev:
Ethyl thioacetate feem ntau yog npaj los ntawm esterification ntawm ethanethioic acid nrog ethanol. Rau txoj kev npaj tshwj xeeb, thov mus saib hauv phau ntawv qhia ntawm lub chaw soj nstuam organic synthesis.
Cov ntaub ntawv kev nyab xeeb:
Ethyl thioacetate yog khaus thiab corrosive thiab yuav tsum tau muab yaug nrog dej ntau tam sim ntawd tom qab sib cuag nrog daim tawv nqaij thiab qhov muag. Thaum siv los yog khaws cia, nws yog ib qho tsim nyog yuav tsum tau ua kom muaj cua txaus thiab tsis txhob sib cuag nrog cov hluav taws kub los tiv thaiv hluav taws thiab tawg. Thaum tuav cov ethyl thioacetate, cov hnab looj tes tiv thaiv, tsom iav tiv thaiv, thiab cov khaub ncaws tiv thaiv uas tiv taus cov kua qaub thiab alkalis yuav tsum hnav kom muaj kev nyab xeeb ntawm tus kheej. Nyob rau hauv cov ntaub ntawv ntawm kev huam yuaj los yog inhalation, nrhiav kev kho mob tam sim ntawd.
