Naphthalene CAS 91-20-3
I-Naphthalene iyikristalu engenambala, ecwebezelayo ye-monoclinic. Inephunga elinamandla le-tarry. Kulula ukwehlisa izinga lokushisa ekamelweni. Ayincibiliki emanzini, kodwa i-ether, i-ethanol, i-chloroform, i-carbon disulfide, i-benzene, njll. I-Naphthalene iyiringidi eyi-hydrocarbon ejikijelwe ebaluleke kakhulu embonini. Isetshenziswa kakhulu ukukhiqiza i-phthalic anhydride, ama-naphthols ahlukahlukene, ama-naphthylamines, njll. Iyindawo emaphakathi yokukhiqizwa kwama-synthetic resins, ama-plasticizers, odayi, ama-surfactants, ama-synthetic fibers, ama-coatings, izibulala-zinambuzane, imithi, amakha, izithasiselo zenjoloba kanye nezibulala-zinambuzane.

1.Imibala edayayo
I-Naphthalene idlala indima ebalulekile ekukhiqizeni udayi, ikakhulukazi njengendawo emaphakathi yodayi. I-naphthalene yezimboni iyimpahla ebalulekile yokwenziwa kodayi abahlukahlukene nezimibalabala, ezifana nodayi be-indigo nezimibalabala eziphuzi. Ngaphezu kwalokho, i-naphthalene ingashintshwa ibe yizinkabi zodayi ezifana ne-β-naphthol, ezibuye zisetshenziswe ekukhiqizeni odayi nemibala. Amazwe ahlukene anezabelo ezihlukene zokusetshenziswa kwe-naphthalene, kodwa okuphakathi kodayi kuhlala kunendawo.
2.Izithasiselo zenjoloba
I-Naphthalene isetshenziswa kakhulu njengesengezo ekucubunguleni irabha. Lokhu kusetshenziswa kubala cishe u-15% wengqikithi yokusetshenziswa kwe-naphthalene. Izithasiselo zenjoloba zidlala indima ebalulekile ekukhiqizweni kwenjoloba. Bangakwazi ukuthuthukisa izakhiwo zenjoloba, njengokuthuthukisa amandla ayo, i-ductility noma ukumelana nesimo sezulu. Njengesengezo senjoloba, i-naphthalene ihlinzeka ngemisebenzi ethile kanye nezici emikhiqizweni yenjoloba, iyenze ifaneleke kakhulu izimo ezihlukahlukene zohlelo lokusebenza.
3. Izibulala-zinambuzane
I-Naphthalene inezicelo ezithile emkhakheni wezibulala-zinambuzane. Nakuba ukusetshenziswa kwe-naphthalene kuhlukahluka kuye ngamazwe, izibulala-zinambuzane zithatha cishe u-6% wokusetshenziswa kwazo. Ikakhulukazi, kwamanye amazwe, njengase-United States, isilinganiso esisetshenziselwa ukukhiqiza izibulala-zinambuzane sikhulu uma kuqhathaniswa. Ngaphezu kwalokho, i-anthracene iphinde isetshenziswe njengesibulala-zinambuzane, ehambisana nezinye izinto ezifana nempahla ye-luminescent kanye nodayi. Lezi zinhlelo zokusebenza zibonisa ukubaluleka kwe-naphthalene ne-anthracene ekulawuleni izinambuzane kwezolimo kanye ne-horticulture.
