Mea Hana Maikaʻi Kumu Butylal (Dibutoxymethane) CAS: 2568-90-3

wehewehe pōkole:

ʻO Butylal (Dibutoxymethane) he mea hoʻoheheʻe halogen ʻole a emi ʻole ka ʻawaʻawa hiki ke hoʻohana ʻia no ka hoʻoheheʻe ʻana i nā laʻana polyethylene haʻahaʻa haʻahaʻa (LDPE) pāʻoihana e kālailai i ka hāʻawi ʻana i ke kaumaha molekala me ka hoʻohana ʻana i ka gel permeation chromatography (GPC).Hiki ke hoʻohana ʻia ka Butylal (Dibutoxymethane) ma ke ʻano he reactant e hoʻomākaukau ai i ka iodide butoxymethyltriphenylphosphonium.Hoʻohana ʻia ʻo Butylal (Dibutoxymethane) no ka homologation kalapona a ma ke ʻano he kī waena pono i ka synthesis organik.
