Dibenzoylmethane Usage Ma Faʻamatalaga

Meatotino vailaʻau: samasama samasama-paʻepaʻe

Faʻaaogaina: antineoplastic

Faʻaaogaina: dibenzoylmethane o se fou faʻamafanafana vevela PVC, maualuga transmittance, leai-oona ma tofo; mafai faʻaleleia atili le vave PVC valivali, manino, tumau-tumau mautu, ma gaioiga i le taimi o timuga ma "zinc mu" ma isi; lautele faʻaaogaina i fomaʻi, meaai afifiina ma isi le oona oona manino oloa PVC. Dibenzoylmethane i luga atu e mafai ona mitiia le 290nm ultraviolet malamalama, ae o le malamalama e i ai le faʻamautinoaina o oloa i luga o oloa a le PVC e mafai ona maua ai se taimi umi tumau falegaʻoga.

Uiga: ChEBI: O le beta-diketone o le acetylacetone (acac) lea na suia uma ai vaega o methyl e vaega phenyl. O se tamaʻi mea e faʻaaofia ai le aʻa o le licorice (Glycyrrhiza glabra) ma faʻaalia antimutagenic ma antica cer aafiaga.         

Talaaga o le Saogalemuina A vevela i le pala e faʻapipiʻi ai le asu ma faʻafuaseʻi ausa       

Metotia Faʻamamaina: Dibenzoylmethane (1,3-diphenyl-1,3-propanedione) [120-46-7] M 224.3, m 8 0o. Crystallize dibenzoylmethane mai fagafao ether poʻo MeOH. [Beilstein 7 IV 2512.]

Fou e le oona vailaʻau fesoasoani faʻamafanafana o le calcium, metala paʻepaʻe ma le lalolagi seasea——Dibenzoylmethane (DIBENZOYL METHANE) O le autu lelei faʻasino igoa: Foliga Vaaia: Paʻepaʻe, malamalama samasama samasama efuefu efuefu Aano: ≥99% Faʻamaʻila vai: 76 ~ 80 ℃ Faʻamagoina leiloa: ≤ 0.5% Aano o mea: ≤0.1% Teuina: 25kg, 50kg Stearoyl benzoyl methane oloa: PVC fou leai-ova fesoasoani faʻamautuina vevela, e mafai ona faʻaaogaina ma ma kalasi / metala paʻepaʻe, barium / metala paʻepaʻe ma elemeni lalolagi elemeni, tofotofoina e le National Research Center ma faʻamaonia le lelei o oloa atoatoa faʻafetaiaʻia le tulaga lelei o tulaga tutusa o oloa i fafo. O la matou kamupani o se tasi o sili tele gaosiina o Dibenzoylmethane ma a matou oloa e tele lava faʻatau atu i Europa, Amerika, Taiwan o Saina, Iapani, Korea i Saute, Lusia, Initia,

Mekisiko, ma isi mea o loʻo iai a matou tagata faʻatau i le silia ma le 40 atunuʻu. Lenei oloa e paʻepaʻe pe malamalama samasama samasama crystalline efuefu, faigofie soluble i ether, trichloromethane, o-Xylene, toluene ma aqueous sodium hydroxide, sina soluble i le ethanol, matua laʻititi soluble i le vai. I le avea ai o se ituaiga fou o le ausilali fesoasoani fesoasoani a le PVC, o lona faʻasalalauga e maualuga, e le oona ma e leai se uiga; mafai ona faʻaaogaina ma mautu poʻo suavai kalama / metala paʻepaʻe, barium / metala paʻepaʻe ma isi vevela stabilizers, mafai ona sili ona faʻaleleia le PVC muamua valivali, manino, ma umi-tumau tulaga mautu, faʻapea foi ma le faʻasusu ma le 'zinc fever' i le faʻagaioiga; o ona uiga e sili ona lelei synergistic aafiaga i le 'sink fasimoli', faʻaopopoina o lenei oloa mafai lelei taofia '' metalaʻila mu ', talafeagai e faʻatino i malo, leai-oona, leai se aoga fanua, faʻalauteleina le faʻaleleia o le Calcium / Zinc compound stabilizer, ia e lautele faʻaaogaina i fomaʻi, meaʻai afifiina ma isi e le oona faʻamaonia oloa PVC (e pei o fagu PVC, laupepa, ata manino ata ma isi). Dibenzoylmethane mafai ona mitiia sili atu nai lo 290nm UV, i le taimi e tasi o le i ai o le gaioiga o le malamalama faʻamautuina, mafai ona maua ai le tumau-tumau mautu i oloa PVC.
