    Kugwiritsa ntchito

    Amagwiritsidwa ntchito kwambiri mu mankhwala, utoto, mankhwala ophera tizilombo ndi zina zotero. Amagwiritsidwanso ntchito muzowonjezera zakudya ndi zokometsera ndi zonunkhira.

    Katundu

    Ethyl acetoacetate ndi madzi opanda mtundu okhala ndi fungo labwino la zipatso. Amasungunuka mosavuta mu ethanol, ethyl ehter, propylene glycol ndi ethyl acetate, komanso kusungunuka m'madzi monga 1:12.

    Kusungirako

    Kusungidwa pa youma, pamthunzi, podutsa mpweya malo.

    Kukhazikika

    1. Khola pansi pa kutentha kwabwino ndi kupanikizika. Zida zosagwirizana: ma acid, alkali, ochepetsa, oxidizing agents. Ndi gulu lachiwopsezo chochepa. Pewani mpweya wopuma komanso kukhudzana ndi khungu.

    Chemical katundu: Umakhala wofiirira ukakumana ndi ferric chloride. Pamene hydrolyzed ndi dilute acid kapena kuchepetsa alkali, acetone, Mowa ndi carbon dioxide amapangidwa. Pansi pa zochita za maziko amphamvu, mamolekyu awiri a asidi acetic ndi ethanol amapangidwa. Pamene kuchepetsa kuchepetsa, β-hydroxybutyric acid amapangidwa. Mu ethyl acetoacetate yomwe yangotulutsidwa kumene, mawonekedwe a enol amawerengera 7% ndipo mawonekedwe a ketone amakhala 93%. Pamene njira ya ethanol ya ethyl acetoacetate itakhazikika mpaka -78 ° C, ketoni ya ketone inalowetsedwa mu crystalline state. Ngati chotumphukira cha sodium cha ethyl acetoacetate chayimitsidwa mu dimethyl ether ndipo mpweya wouma wa hydrogen chloride wouma umadutsa pa -78 ° C, mafuta a enol amatha kupezeka.

    2. Mankhwalawa alibe poyizoni, makoswe amamwa LD503.98g/kg. Koma ndi kupsa mtima pang'ono ndi anesthesia, zida zopangira ziyenera kusindikizidwa ndi mpweya wabwino. Oyendetsa ali ndi zida zodzitetezera.
