Uruganda Igiciro Cyiza Butylal (Dibutoxymethane) CAS: 2568-90-3

ibisobanuro bigufi:

Butylal (Dibutoxymethane) ni halogene idafite imbaraga kandi idafite ubumara buke bushobora gukoreshwa mugukemura ibibazo byubucuruzi buke buke bwa polyethylene (LDPE) kugirango isesengure ikwirakwizwa ryibiro bya molekile ikoresheje chromatografi ya gel (GPC).Butylal (Dibutoxymethane) irashobora kandi gukoreshwa nkigisubizo cyo gutegura butoxymethyltriphenylphosphonium iyode.Butylal (Dibutoxymethane) ikoreshwa mugukoresha karubone kandi nanone nkurufunguzo rwingirakamaro hagati muri synthesis.
