Mawu Oyamba

Ethyl 3-hydroxybutyrate, yomwe imadziwikanso kuti butyl acetate, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira, ndi chidziwitso cha chitetezo.

chilengedwe:
Ethyl 3-hydroxybutyrate ndi madzi opanda mtundu komanso fungo la zipatso. Amasungunuka mu zosungunulira zambiri monga ether, mowa, ndi ketone. Ili ndi kusinthasintha kwapakati.

Cholinga:
Ethyl 3-hydroxybutyrate chimagwiritsidwa ntchito makampani monga chigawo chimodzi cha zonunkhira ndi akamanena, amene angapereke zipatso kukoma kwa mankhwala ambiri, monga kutafuna chingamu, timbewu, zakumwa ndi mankhwala fodya.

Njira yopanga:
Kukonzekera kwa ethyl 3-hydroxybutyrate nthawi zambiri kumachitika kudzera mu ester exchange reaction. Bweretsani butyric acid ndi ethanol pansi pa acidic kuti mupange ethyl 3-hydroxybutyrate ndi madzi. Pambuyo pomaliza, mankhwalawa amayeretsedwa ndi distillation ndi rectification.

Zambiri zachitetezo:
Ethyl 3-hydroxybutyrate nthawi zambiri imawonedwa ngati yotetezeka pakagwiritsidwe ntchito bwino. Monga mankhwala, amatha kuyambitsa khungu, maso, ndi kupuma. Njira zoyenera zotetezera ziyenera kuchitidwa pakukhudzana, monga kuvala magolovesi oteteza, magalasi, ndi masks. Pewani kupuma molunjika kapena kumeza mukamagwiritsa ntchito.

Zam'mbuyo: 3-Mercaptohexyl acetate(CAS#136954-20-6)

Ena: Ethyl 3-hydroxyhexanoate(CAS#2305-27-1)
