Mawu Oyamba

Ethyl benzoate) ndi organic pawiri yomwe ndi madzi opanda mtundu pa kutentha kwa firiji. Zotsatirazi ndizo zokhudzana ndi katundu, ntchito, njira zokonzekera ndi chitetezo cha ethyl benzoate:

 

Ubwino:

Lili ndi fungo lonunkhira komanso limasinthasintha.

Zosungunuka mu zosungunulira organic monga ethanol, etha, ndi zina, zosasungunuka m'madzi.

 

Gwiritsani ntchito:

Ethyl benzoate imagwiritsidwa ntchito makamaka ngati zosungunulira m'mafakitale monga utoto, guluu ndi kupanga makapisozi.

 

Njira:

Kukonzekera kwa ethyl benzoate nthawi zambiri kumachitika ndi esterification. Njira yeniyeni imaphatikizapo kugwiritsa ntchito benzoic acid ndi ethanol monga zopangira, ndipo pamaso pa chothandizira asidi, zomwe zimachitika pa kutentha koyenera ndi kukakamizidwa kuti mupeze ethyl benzoate.

 

Zambiri Zachitetezo:

Ethyl benzoate imakwiyitsa komanso yosasunthika ndipo iyenera kupewedwa pokhudzana ndi khungu ndi maso.

Chidwi chiyenera kuperekedwa ku mpweya wabwino panthawi ya chithandizo kuti musapume mpweya kapena kutulutsa mpweya.

Posunga, pewani kutentha ndi malawi otseguka, ndipo chidebecho chitsekedwe mwamphamvu.

Ngati mwakowetsedwa kapena kukhudza mwangozi, pitani kumalo opumirako mpweya kuti muyeretsedwe kapena mukapeze chithandizo chamankhwala munthawi yake.
