Intangiriro
α-propyl-γ-butyrolactone (izwi kandi nka α-MBC) ni ibisanzwe bisanzwe. Ifite ibara ritagira ibara kandi ridafite impumuro nziza kandi rifite ubushyuhe buke bwo guhinduka mubushyuhe bwicyumba. Dore ibisobanuro birambuye kuri α-propyl-γ-butyrolactone:
Ubwiza:
- α-propyl-γ-butyrolactone ifite imbaraga zo gushonga kandi irashobora gushonga ibintu byinshi kama nkibisigazwa, amarangi hamwe nudusanduku.
- Iyi lactone ntabwo yaka, ariko irashobora kubyara imyuka yuburozi mubushyuhe bwinshi.
Koresha:
.
Uburyo:
- α-propyl-γ-butyrolactone isanzwe itegurwa na esterification ya γ-butyrolactone. Muri ubu buryo, γ-butyrolactone ikora na acetone kandi birenze aside hydrochloric cyangwa aside sulfurike yongeweho nka catalizator.
Amakuru yumutekano:
- Mugihe ukoresha α-propyl-γ-butyrolactone, irinde guhura igihe kirekire nuruhu no guhumeka gaze.
- Ingamba n’umutekano zikwiye zigomba gukurikizwa mugihe cyo kubika no gutunganya α-propyl-γ-butyrolactone.
