    Application

    Inonyanya kushandiswa mumishonga, dyestuff, pesticide uye zvichingodaro. Inoshandiswawo muzvokudya zvinowedzera uye zvinonaka uye zvinonhuhwirira.

    Property

    Ethyl acetoacetate imvura isina ruvara ine muchero unonhuhwirira. Inonyungudika nyore mu ethanol, ethyl ehter, propylene glycol uye ethyl acetate, uye inonyungudika mumvura se1:12.

    Storage

    Kuchengetwa panzvimbo yakaoma, ine mumvuri, ine mhepo.

    Kugadzikana

    1. Yakagadzikana pasi pekushisa kwemazuva ose uye kumanikidzwa. Zvinhu zvisingaenderani: acids, alkalis, zvinoderedza, oxidizing agents. Icho chikamu chepasi-chepfu. Dzivisa kufema mhute uye kubata neganda.

    Chemical properties: Ipepuru kana yasangana neferric chloride. Kana hydrolyzed ine dilute acid kana dilute alkali, acetone, ethanol uye kabhoni dhaikisaidhi inogadzirwa. Pasi pekuita kwechigadziko chakasimba, mamorekuru maviri eacetic acid uye ethanol anogadzirwa. Kana catalytic kuderedza, β-hydroxybutyric asidhi inoumbwa. Mune ichangobva kucheneswa ethyl acetoacetate, iyo enol fomu inoita 7% uye ketone fomu inotora 93%. Apo iyo ethanol solution ye ethyl acetoacetate yakanyoroveswa kusvika -78 ° C, ketone compound yakasvibiswa mu crystalline state. Kana iyo sodium derivative ye ethyl acetoacetate yakamiswa mu dimethyl ether uye zvishoma zvishoma zvishoma zvishoma zvakasvibiswa zvegasi yakaoma yehydrogen chloride inopfuudzwa pa -78 ° C, mafuta anol compound anogona kuwanikwa.

    2. Ichi chigadzirwa hachina chepfu, gonzo remuromo LD503.98g/kg. Asi nekushatirwa kuri pakati nepakati uye anesthesia, midziyo yekugadzira inofanirwa kuvharwa uye kufefeterwa zvakanaka. Maoperator ane midziyo yekudzivirira.
