Dibenzoylmethane Whakamahi me te Hangarau

Nga Taonga Matū: puehu kowhai-ma

Whakamahinga: antineoplastic

Whakamahinga: dibenzoylmethane hei kaiwhakangungu wera hou o te PVC, he teitei te whakawhiti, kaore he paitini me te koretake. ka taea te whakapai ake i te tae whero o te PVC, te maarama, te pumau o te wa roa, me te tukatuka i te wa e heke ana te ua me te "wera konutea" me te aha ano; whakamahia whānuitia ai i roto i te rongoa, tākai kai me etahi atu hua PVC maramara kore-paitini. Ka taea e Dibenzoylmethane i runga ake te ngongo i te rama ultraviolet 290nm, i te wa e maama ana te hua ki nga hua pvc ka taea te mahi pumau mo te wa roa.

Whakamarama: ChEBI: He beta-diketone he acetylacetone (acac) i roto i nga roopu methyl e rua i whakakapihia e nga roopu phenyl. He mea iti noa te waahanga pakiaka o te raihana (Glycyrrhiza glabra) me te whakaatu antimutagenic me te antica cer effects.         

Pūkete Haumaru: He paitini i te horomia. Ka werahia ki te pirau ka puta te auahi auahi me nga kohu whakararu       

Nga Tikanga mo te Purea: Dibenzoylmethane (1,3-diphenyl-1,3-propanedione) [120-46-7] M 224.3, m 8 0o. Whakanuihia te dibenzoylmethane mai i te pether ether me te MeOH. [Beilstein 7 IV 2512.]

Ko te whakauo wera hou-kore awhina o te konupūmā, konutea me te whenua onge ——Dibenzoylmethane (DIBENZOYL METHANE) Te taupū kounga kounga matua: Ahua: Ma, ma te kowhai kowhai kowhai kowhatu paura Ihirangi: ≥99% Ira rewa: 76 ~ 80 ℃ Ngaro maroke: ≤ 0.5% Te kiko o te pungarehu: ≤0.1% Te whakakii: 25kg, 50kg Stearoyl benzoyl methane hua: Ka taea te whakamahi i te pvc stabilizer awhina-kore-taapiri hou, me te konupūmā / konutea, barium / konutea me nga mea onge o te whenua, i whakamatauria e te National Research Center i whakamatauhia te kounga o nga hua ka tutuki i nga paerewa kounga o nga hua ke o whenua ke. Ko ta maatau kamupene tetahi o nga kaihanga nui o Dibenzoylmethane me a maatau hua e hokona ana ki te Pakeha, Amerika, Taiwan o Haina, Japan, Korea ki te Tonga, Russia, India,

Mexico, aha atu, he kaihoko ano taatau kei roto i nga whenua 40 neke atu. Ko tenei hua he ma, he maama ranei te paura kowhai kowhai, ngawari te wairewa i roto i te ether, trichloromethane, o-Xylene, toluene me te waikawa konutai waihoe, he wairewa nei i te waihono, he iti nei te wairewa i te wai. Hei momo hou o te kaitapahi wera awhina awhina a te PVC, he nui, kaore he paitini, he koretake hoki te whakawhiti; ka taea te whakamahi ma te konupūmā / waipiro / konutea, barium / konutea me etahi atu kaiwhakarite wera, ka taea te whakapai ake i te tae tuatahi o te PVC, te maarama, me te pumau o te wa roa, me te rerenga me te 'zinc fever' i te tukatuka; tona ahuatanga he pai te painga o te synergistic ki te 'hopi hopi', ko te taapiri o tenei hua ka aukati i te 'mura konutea', he pai ki te whakauru i roto i te maroke, kore-paitini, mara koretake, whakatairanga i te whakahoutanga o te konuputu konupūmā / konutea, e whakamahia whānuitia ana i roto i te rongoa, tākai kai me etahi atu hua pvc kore-paitini (penei i nga pounamu pvc, pepa, kiriata marama me etahi atu). Ka taea e Dibenzoylmethane te mimiti neke atu i te 290nm UV, i te wa ano he mahi maamaa te whakamarama, ka taea te whakarato i te pumau o te wa roa mo nga hua PVC.
