Dibenzoylmethane Hoʻohana a me Synthesis

Nā Pono Kemika: he melemele-keʻokeʻo pauka

Hoʻohana: antineoplastic

Hoʻohana: dibenzoylmethane ma ke ʻano he stabilizer PVC hou, hoʻolawe kiʻekiʻe, ʻaʻohe mea ʻawahia a me nā mea ʻono ʻole; hiki ke hoʻomaikaʻi maikaʻi i ka pena ʻana o ka wanaʻao PVC, ka transparency, ke kūpaʻa lōʻihi, a me ka hana ʻana i ka wā o ka ua a me ka "zinc burn" a pēlā aku; hoʻohana ākea ʻia i ka lāʻau lapaʻau, ʻūlū meaʻai a me nā huahana PVC aniani ʻole ʻino ʻino. Hiki i ka Dibenzoylmethane ma luna ke komo i ke kukui ultraviolet 290nm, ʻoiai ka hopena me ka hopena i nā huahana PVC hiki ke hāʻawi i ka hana paʻa paʻa lōʻihi.

Wehewehe: ChEBI: ʻO kahi beta-diketone ʻo ia ka acetylacetone (acac) kahi i pani ʻia ai nā hui methyl ʻelua e nā hui phenyl. He mea nui ia o ka aʻa aʻa o licorice (Glycyrrhiza glabra) a hōʻike i nā antimutagenic a me nā hopena antica cer.

Hiki i ka Dibenzoylmethane ke omo i ka mea he nui aʻe ma mua o 290nm UV, i ka manawa like me ka hana o ka hoʻomālamalama kukui, hiki ke hāʻawi i ke kūpaʻa lōʻihi ma nā huahana PVC.
