Isingeniso
I-α-propyl-γ-butyrolactone (eyaziwa nangokuthi i-α-MBC) iyincibilikisi evamile yemvelo. Inoketshezi olungenambala futhi olungenaphunga futhi inezinga eliphansi lokuhwamuka ekamelweni lokushisa. Nansi imininingwane mayelana ne-α-propyl-γ-butyrolactone:
Ikhwalithi:
- I-α-propyl-γ-butyrolactone inokuncibilika okuhle kakhulu futhi ingancibilikisa izinto eziningi eziphilayo ezifana nama-resin, amapende nama-coatings.
- Le lactone ayishi, kodwa ingakhiqiza amagesi anobuthi emazingeni okushisa aphezulu.
Sebenzisa:
- I-α-Propyl-γ-butyrolactone isetshenziswa kabanzi ezinqubweni zokukhiqiza zezimboni zezincibilikisi, amagwebu, amapende, ama-coatings, ama-adhesives, nemikhiqizo yepulasitiki.
Indlela:
- I-α-propyl-γ-butyrolactone ivame ukulungiswa nge-esterification ye-γ-butyrolactone. Kule nqubo, i-γ-butyrolactone isabela nge-acetone futhi okweqile kwe-hydrochloric acid noma i-sulfuric acid yengezwa njenge-catalyst.
Ulwazi Lokuphepha:
- Uma uphatha i-α-propyl-γ-butyrolactone, gwema ukuthintana isikhathi eside nesikhumba kanye nokuhogela amagesi.
- Izinyathelo ezifanele zokuphepha nemithethonqubo kufanele ilandelwe lapho ugcina futhi uphatha i-α-propyl-γ-butyrolactone.
