Zogulitsa

M'modzi mwa FURANS wokhala ndi carbonyl potero amapanga lactone yozungulira. Ndi chophatikizika chopangidwa kuchokera ku gamma-aminobutyrate ndipo chimayambitsanso gamma-hydroxybutyrate. Amagwiritsidwanso ntchito ngati wothandizira mankhwala ndi zosungunulira.

Kusungunuka kwa Madzi

ZOSAVUTA

Mapulogalamu:
Pansi pa zinthu zowoneka bwino zimapanga mgwirizano wamagulu onsewo. Izi zimatha kupitiliza kupanga polima. Mukachiritsidwa ndi non-nucleophilic base, monga lithiamu diisopropylamide, Butyrolactone imatha kukhala alpha-carbon nucleophile. Chida chofananira cha caprolactone chitha kugwiritsidwa ntchito popanga polyester motere.

Butyrolactone sikugwira ntchito yokha; magwiridwe ake amachokera kuti amadziwika kuti ndi prodrug wa.
Zotsatira zakusokoneza bongo kumakwezedwa ndikuphatikiza ndi mowa. Kafukufuku wamakoswe aku 2003 adawonetsa kuti Butyrolactone kuphatikiza ndi ethanol idawonetsa zamatsenga, popeza njira yogona nthawi yayitali kuposa zonse zomwe zidaphatikizidwa

Butyrolactone ndi madzi opanda poizoni owonekera ngati mawonekedwe amafuta. Itha kusakanizidwa ndi madzi ndikusungunuka ndi ethanol ether, benzene ndi acetone. Itha kusungunula zinthu zina zambiri zachilengedwe. Kugwiritsa ntchito Butyrolactone ndi kotetezeka komanso kosavuta, chifukwa ndimadzi otentha kwambiri, osungunuka mwamphamvu, magetsi abwino komanso kukhazikika.Butyrolactone ndichinthu chofunikira kwambiri chopangira zinthu zopangira komanso zosungunulira zabwino. Amagwiritsidwa ntchito makamaka ngati zopanga za pyrolidone zopangidwa ndi cyclopropylamine acetyl-r-butyrolactone, kuphatikiza pa izi, Butyrolactone imagwiritsidwanso ntchito ngati zosungunulira mankhwala aulimi, polima, dyestuff ndi kusindikiza. Pogwiritsa ntchito butyrolactone ngati zopangira, titha kupanga mankhwala onunkhira, othandizira apakati komanso othandizira dzimbiri.

Zotsatira za y-Butyrolactone:
Kuyambitsa kupumula.
Kuchulukitsa kwamalingaliro.
Kuthetsa kupsinjika ndi kupsinjika.
Kutalikitsa moyo.
Kupititsa patsogolo magwiridwe antchito ndi chisangalalo.
Kuchepetsa mafuta.
Kupititsa patsogolo masewera othamanga.
Kusintha tulo.
Monga womanga thupi kapena womanga minofu.
Monga mankhwala osangalatsa.

1) Itha kugwiritsidwa ntchito kupangira zinthu za pyrrolidone;
2) Itha kugwiritsidwa ntchito ngati mankhwala apakatikati, monga Cyclopropylamine ndi vitamini;
3) Itha kugwiritsidwa ntchito ngati mankhwala apakatikati, monga herbicide ndikukula kwazomera;
4) Itha kugwiritsidwa ntchito kwa alkenes, alkynes m'zigawo, wothandizila ndi wobalalitsa wothandizila;
5) Ikhoza kugwiritsidwa ntchito kupanga utomoni monga antioxidant, plasticizer, dispersing agent, fixing agent ndi solvent;
6) Thiabendazole angagwiritsidwe ntchito kuti lithe CHIKWANGWANI kupota zosungunulira, coagulant, ankaudaya wothandizira ndi wothandizila antistatic;
7) Itha kugwiritsidwa ntchito ngati zopangira zamtundu wa kanema wakale, electrolyte, capacitor ndi mafuta opangira inki.
