Dibenzoylmethane Kushandisa Uye Synthesis

Chemical Properties: yero-chena hupfu

Zvishandiso: antineoplastic

Zvishandiso: dibenzoylmethane seyaka nyowani PVC kupisa inodzikamisa, yakakwira transmittance, isina-chepfu uye isina kunaka; inogona kuvandudza zvakanyanya yekutanga PVC kupenda, kujekesa, kugadzikana kwenguva refu, uye kugadzirisa panguva yemvura uye "zinc kupisa" zvichingodaro; inoshandiswa zvakanyanya mune zvekurapa, kurongedza chikafu uye zvimwe zvisina-chepfu zviripachena zvigadzirwa zvePVC. Dibenzoylmethane pamusoro inogona kutora 290nm ultraviolet mwenje, nepo mwenje uine kugadzikana kune izvo zvigadzirwa zvePVV zvinogona kupa kwenguva refu kugadzikana kuita.

Tsanangudzo: CHEBI: Beta-diketone iri acetylacetone (acac) umo mapoka ese emethyl akatsiviwa nemaphenyl mapoka. Icho chikamu chidiki chemudzi wekutora we licorice (Glycyrrhiza glabra) uye inoratidza antimutagenic uye antica cer mhedzisiro.         

Chengetedzo Mbiri: Zvine mwero chepfu nekumedza. Kana yadziirwa kuora inoburitsa utsi hweacid uye inopisa mweya       

Maitiro Ekuchenesa: Dibenzoylmethane (1,3-diphenyl-1,3-propanedione) [120-46-7] M 224.3, m 8 0o. Crystallize dibenzoylmethane kubva pet ether kana MeOH. [Beilstein 7 IV 2512.]

Nyowani isiri-chepfu yekubatsira kupisa inodzikamisa calcium, zinc uye isingawanzo pasi -—Dibenzoylmethane (DIBENZOYL METHANE) Iyo hombe mhando index: Chitarisiko: Chena, mwenje yero kristallini hupfu Zvemukati: ≥99% Melting points: 76 ~ 80 ℃ Kuomesa kurasikirwa: ≤ 0.5% Ash zvemukati: ≤0.1% Kurongedza: 25kg, 50kg Stearoyl benzoyl methane zvigadzirwa: PVC nyowani isiri-chepfu yekubatsira yekudzikamisa kupisa, inogona kushandiswa ne calcium / zinc, barium / zinc uye zvisingawanzo pasi zvinhu, zvakaedzwa neNational Research Center. uye yakaratidza mhando yezvigadzirwa zvizere zvinosangana nemhando yepamusoro yezvinhu zvakafanana zvekunze zvigadzirwa. Kambani yedu ndeimwe yegadziri hombe yeDibenzoylmethane uye zvigadzirwa zvedu zvinonyanya kutengeswa kuEurope, America, Taiwan yeChina, Japan, South Korea, Russia, India,

Mexico, nezvimwewo uye isu tine vatengi mune dzinopfuura makumi mana nyika. Ichi chigadzirwa chine chena kana chakajeka yero crystalline poda, inogadzikana nyore nyore muether, trichloromethane, o-Xylene, toluene uye aqueous sodium hydroxide, yakanyungudika zvishoma mu ethanol, yakanyungudika zvishoma mumvura. Semhando nyowani yePVC yekubatsira kupisa inodzikamisa, kutumira kwayo kwakakwirira, kusiri-chepfu uye hakuna kunaka; inogona kushandiswa ne solid kana emvura calcium / zinc, barium / zinc uye zvimwe zvinopisa kupisa, inogona kuvandudza zvakanyanya PVC yekutanga kuchenesa, kujeka, uye kugadzikana kwenguva refu, pamwe nekunaya uye 'zinc fever' mukugadzirisa; hunhu hwayo ine yakanaka kwazvo synergistic mhedzisiro kune 'zinc sipo', kuwedzerwa kwechigadzirwa ichi kunogona kudzivisa 'zinc kupisa', inokodzera kuitisa mumunda wakaomarara, usina-chepfu, usinganetsi, kusimudzira kukwidziridzwa kweCalcium / Zinc chigadzikane, Inoshandiswa zvakanyanya mukurapa, kurongedza chikafu uye zvimwe zvisina-chepfu zvinoonekera zvigadzirwa zvePVC (senge mabhodhoro ePVC, machira, firimu rinoonekera etc.). Dibenzoylmethane inogona kutora anopfuura 290nm UV, panguva imwechete iine basa rekudzikiswa kwechiedza, inogona kupa kugadzikana kwenguva refu pazvigadzirwa zvePVC.
