Kugwiritsa Ntchito Dibenzoylmethane Ndi kaphatikizidwe

Katundu wa Chemical: ufa wonyezimira

Gwiritsani ntchito: antineoplastic

Gwiritsani ntchito: dibenzoylmethane ngati PVC yatsopano yolimbitsa kutentha, kupititsa patsogolo kwambiri, yopanda poizoni komanso yopanda tanthauzo; Zitha kusintha kwambiri mitundu ya PVC yoyambirira, kuwonekera poyera, kukhazikika kwakanthawi, ndikukonzanso nthawi yamvula ndi "zinc burn" ndi zina zotero; ankagwiritsa ntchito mankhwala, ma CD chakudya ndi zina sanali poizoni mandala mankhwala PVC. Dibenzoylmethane pamwambapa imatha kuyamwa kuwala kwa 290nm ultraviolet, pomwe kuwala komwe kumapangitsa kuti zinthu zizikhala zolimba pazinthu za PVC kumatha kupereka magwiridwe antchito kwanthawi yayitali.

Tanthauzo: CHEBI: beta-diketone yomwe ndi acetylacetone (acac) momwe magulu onse a methyl adasinthidwa ndi magulu a phenyl. Ndi gawo laling'ono la muzu wa licorice (Glycyrrhiza glabra) ndipo imawonetsa zotsatira za antimutagenic ndi antica cer.         

Mbiri Yachitetezo: Poizoni pang'ono pomeza. Ikatenthedwa kuti iwonongeke imatulutsa utsi wakupha komanso nthunzi zoyipa       

Njira Zoyeretsera: Dibenzoylmethane (1,3-diphenyl-1,3-propanedione) [120-46-7] M 224.3, m 8 0o. Crystallize dibenzoylmethane kuchokera ku pet ether kapena MeOH. [Beilstein 7 IV 2512.]

Watsopano wopanda poizoni wothandizira kutentha kwa calcium, zinki ndi nthaka yosawerengeka -—Dibenzoylmethane (DIBENZOYL METHANE) Chizindikiro chachikulu cha mawonekedwe: Kuwonekera: White, kuwala kofiira ufa wonyezimira: ≥99% Malo osungunuka: 76 ~ 80 ℃ Kuyanika kutayika: loss 0,5% Ash okhutira: ≤0.1% Kulongedza: 25kg, 50kg Stearoyl benzoyl methane mankhwala: PVC yatsopano yopanda poizoni yothandizira kutentha, ingagwiritsidwe ntchito ndi calcium / zinc, barium / zinc ndi zinthu zosowa zapadziko lapansi, zoyesedwa ndi National Research Center ndipo zatsimikizira kuti mtunduwo wazogulitsazo umakwaniritsa miyezo yabwinobwino yazinthu zofananira zakunja. Kampani yathu ndi imodzi mwazipangidwe zazikulu za Dibenzoylmethane ndipo zogulitsa zathu zimagulitsidwa ku Europe, American, Taiwan yaku China, Japan, South Korea, Russia, India,

Mexico, ndi zina zambiri ndipo tili ndi makasitomala m'maiko opitilira 40. Izi ndizoyera kapena zoyera zachikasu ufa, zosungunuka mosavuta mu ether, trichloromethane, o-Xylene, toluene ndi amadzimadzi a sodium hydroxide, osungunuka pang'ono mu ethanol, osungunuka pang'ono pang'ono m'madzi. Monga mtundu watsopano wa PVC wothandizira kutentha kokhazikika, kupitilira kwake ndikokwera, kosakhala koopsa komanso kosapweteka; itha kugwiritsidwa ntchito ndi calcium / zinc yolimba kapena yamadzi, barium / zinc ndi zina zotetezera kutentha, zitha kusintha kwambiri mtundu wa PVC, kuwonekera poyera, ndi kukhazikika kwakanthawi, komanso mpweya ndi 'zinc fever' pokonza; mawonekedwe ake ili ndi mgwirizano wabwino kwambiri ku 'zinc sopo', kuwonjezera kwa mankhwalawa kumatha kuletsa 'kuyaka kwa zinc', koyenera kukhazikitsa m'munda wolimba, wopanda poizoni, wopanda vuto, kulimbikitsa kukweza kwa kompositi ya calcium / Zinc, chimagwiritsidwa ntchito popanga mankhwala, kulongedza chakudya komanso zinthu zina zopanda poizoni za PVC (monga mabotolo a PVC, mapepala, kanema wowonekera etc.). Dibenzoylmethane imatha kuyamwa zoposa 290nm UV, nthawi yomweyo kukhala ndi bata, zimatha kukhazikika kwanthawi yayitali pazinthu za PVC.
