L-2-Aminobutanol (CAS# 5856-62-2)

Mawu Oyamba

(S)-( ) -2-Amino-1-butanol ndi organic pawiri ndi mankhwala chilinganizo C4H11NO. Ndi molekyulu ya chiral yokhala ndi enantiomers awiri, omwe (S) - ( ) -2-Amino-1-butanol ndi imodzi.

(S)-( )-2-Amino-1-butanol ndi madzi opanda mtundu komanso fungo loipa. Imasungunuka m'madzi ndi zosungunulira zomwe zimapezeka m'madzi monga ma alcohols ndi ethers.

Kugwiritsiridwa ntchito kofunikira kwa mankhwalawa kumakhala ngati chothandizira cha chiral. Angagwiritsidwe ntchito asymmetric catalysis mu organic kaphatikizidwe zimachitikira, monga asymmetric synthesis amines ndi kaphatikizidwe wa chiral heterocyclic mankhwala. Komanso zothandiza monga wapakatikati mu kaphatikizidwe mankhwala.

Njira yokonzekera (S)-( ) -2-Amino-1-butanol imaphatikizapo njira ziwiri zazikulu. Chimodzi ndicho kupeza aldehyde mwa carbonylation ya carboxylic acid kapena ester, yomwe imachitidwa ndi ammonia kuti ipeze mankhwala omwe akufuna. Zina ndi kupeza butanol pochita hexanedione ndi refluxing magnesium mu mowa, ndiyeno kupeza chandamale mankhwala mwa kuchepetsa anachita.

Njira zina zodzitetezera ziyenera kutsatiridwa mukamagwiritsa ntchito ndikusunga (S) - ( ) -2-Amino-1-butanol. Ndi madzi omwe amatha kuyaka ndipo amafunika kusungidwa kutali ndi moto wotseguka komanso kutentha kwakukulu. Zida zotetezera zoyenera, monga magolovesi a mankhwala ndi magalasi, ndizofunikira kuti zigwiritsidwe ntchito. Pewani kukhudzana ndi khungu ndi inhalation ya nthunzi yake. Kutaya kumafunika motsatira malamulo oyendetsera zinyalala m'deralo.
