3. Kev ua haujlwm zoo li cov khoom siv tshuaj zoo, txhim khu kev qha cov nplaim hluav taws thiab cov ntaub ntawv siv lead ua kua nrog cov thermal stability zoo rau cov ntaub ntawv polymer thiab cov ntaub ntawv tshawb fawb.
Cia thiab ceev faj
Khaws 1 4-Dibromonaphthalene CAS 83-53-4 (dawb crystalline hmoov, mp 80-83 degree, ceev 1.98g/cm³, bp 321 degree, purity ntau dua los yog sib npaug rau 98%, lub teeb{15-degree PE nyob rau hauv PE-stable) nruas / amber iav ntim rau hauv qhov chaw txias, qhuav, zoo-ventilated, deb ntawm qhib hluav taws, muaj zog oxidants thiab kub kub. Hnav hnab looj tes nitrile, looj tsom iav dub thiab plua plav npog; zam plua plav nqus, tawv nqaij/qhov muag thiab noj kom tsis txhob mob me me. Reseal nruj nreem tom qab siv; pov tseg cov pov tseg ib cheeb tsam halogenated naphthalene ib puag ncig cov cai.
Dab tsi yog qhov txiaj ntsig ntawm kev noj 1 4-Dibromonaphthalene?
1 4-Dibromonaphthalene CAS 83-53-4 yog ib qho kev lag luam dibrominated aromatic intermediate, tsis yog rau tib neeg kev sib cuag los yog kev noj; Cov plua plav uas tsis muaj hmoov av tuaj yeem ua rau ua pa me me / tawv nqaij khaus, thiab siab - kub combustion tso tawm cov pa phem brominated.
Hauv kev tswj hwm kev siv, 1 4-Dibromonaphthalene CAS 83-}53-4 nta siab bromine hloov purity thiab zoo heev cross-coupling reactivity, zoo solubility nyob rau hauv cov kuab tshuaj organic, zoo heev thermal / tshuaj stability, thiab 1,4-disubstituted qauv enables meej symmetric hloov kho rau diversified synthesis.
