Naphthalene CAS 91-20-3
INaphthalene yikristale engenambala, ecwebezelayo ye-monoclinic. Inevumba elinamandla letela. Kulula ukuzithoba kwiqondo lokushisa. Ayinyibiliki emanzini, kodwa iyanyibilika kwi-ether, ethanol, kwiklorofomu, kwikhabhoni disulfide, benzene, njalo njalo. INaphthalene yeyona ring ibalulekileyo yeringi yehydrocarbon kwishishini. Isetyenziselwa ikakhulu ukuvelisa i-phthalic anhydride, i-naphthols eyahlukeneyo, i-naphthylamines, njl. njl

1.Idayi ephakathi
INaphthalene idlala indima ephambili kwimveliso yedayi, ngakumbi njengedayi ephakathi. I-naphthalene ye-Industrial iyinto ebalulekileyo ekrwada ekwenzeni iindidi zedayi kunye nee-pigments, ezifana ne-indigo dyes kunye ne-yellow pigments. Ukongeza, i-naphthalene inokuguqulwa ibe yimida yedayi efana ne-β-naphthol, ephinda isetyenziswe kwimveliso yedayi kunye neepigments. Amazwe ahlukeneyo anezabelo ezahlukeneyo zokusetyenziswa kwe-naphthalene, kodwa iziphakathi zedayi zihlala zinendawo.
2.Izongezo zerabha
I-Naphthalene isetyenziswa kakhulu njenge-additive kwi-rubber processing. Olu setyenziso lubalelwa malunga ne-15% yokusetyenziswa okupheleleyo kwe-naphthalene. Izongezo zerabha zidlala indima ephambili kwimveliso yerabha. Bangakwazi ukuphucula iimpawu zerubha, ezifana nokuphucula amandla ayo, i-ductility okanye ukuchasana kwemozulu. Njengesongezo se-rubber, i-naphthalene inikezela ngemisebenzi ethile kunye neempawu kwiimveliso zerabha, okwenza ukuba zifaneleke ngakumbi kwiimeko ezahlukeneyo zesicelo.
3. Amayeza okubulala izinambuzane
I-Naphthalene inezicelo ezithile kwintsimi ye-insecticide. Nangona ukusetyenziswa kwe-naphthalene kuyahluka kumazwe ngamazwe, i-insecticide ibala malunga ne-6% yokusetyenziswa kwayo. Ngokukodwa, kwamanye amazwe, anjengeUnited States, umlinganiselo osetyenziswayo ekuveliseni amayeza okubulala izinambuzane mkhulu ngokwentelekiso. Ukongeza, i-anthracene iphinda isetyenziswe njengesibulala-zinambuzane, ehlala kunye nezinye izinto ezifana nezixhobo zokukhanya kunye nedayi. Ezi zicelo zibonisa ukubaluleka kwe-naphthalene kunye ne-anthracene yokulawula izinambuzane kwezolimo kunye ne-horticulture.
