Mawu Oyamba

Ethyl (R)-(-)-3-hydroxybutyrate, yomwe imadziwikanso kuti (R)-(-)-3-hydroxybutyric acid ethyl ester, ndi organic pawiri. Makhalidwe ake ndi awa:

 

Ubwino:

- Maonekedwe: Madzi opanda mtundu

 

Gwiritsani ntchito:

Ethyl (R)-(-)-3-hydroxybutyrate ili ndi mitundu ingapo yogwiritsira ntchito mu chemistry:

- Imatha kutenga gawo lofunikira ngati chothandizira pakupanga kaphatikizidwe ka organic.

 

Njira:

Pali njira zingapo zokonzekera ethyl (R)-(-)-3-hydroxybutyrate:

- Njira wamba ndi kukonzekera ndi esterification wa asidi hydroxybutyric, amene amachitira asidi hydroxybutyric ndi Mowa, amawonjezera asidi chothandizira monga sulfuric asidi kapena formic acid, ndi distills koyera mankhwala pambuyo anachita.

- Itha kukonzedwanso powonjezera succinic acid ndi ethanol, kuwonjezera zopangira asidi, kenako hydrolysis.

 

Zambiri Zachitetezo:

Ethyl (R)-(-)-3-hydroxybutyrate ndiyotetezeka kuti igwiritsidwe ntchito wamba, koma zotsatirazi ziyenera kudziwidwa:

- Ndi madzi oyaka moto ndipo ayenera kupewa kukhudzana ndi moto wotseguka komanso kutentha kwambiri.

- Njira zodzitetezera zofunikira, monga kuvala magalasi oteteza ndi magolovesi, ziyenera kuchitidwa panthawi yogwira ntchito.

- Pewani kutulutsa mpweya, kumeza, komanso kukhudza khungu ndi khungu kuti musamve bwino komanso kuvulala.

- Mukakhudza, sambani malo omwe akhudzidwa nthawi yomweyo ndi madzi ambiri ndikupita kuchipatala.
