Naphthalene CAS 91-20-3
Naphthalene ke kristale e se nang 'mala, e benyang ea monoclinic. E na le monko o matla oa tarry. Ho bonolo ho nyenyefatsa mocheso oa kamore. Ha e qhibilihe metsing, empa e qhibiliha ka har'a ether, ethanol, chloroform, carbon disulfide, benzene, joalo-joalo. Naphthalene ke ring hydrocarbon ea bohlokoa ka ho fetisisa indastering. E sebelisoa haholo-holo ho hlahisa anhydride ea phthalic, naphthols tse fapa-fapaneng, naphthylamines, joalo-joalo Ke sebaka se bohareng bakeng sa tlhahiso ea li-resin tsa maiketsetso, li-plasticizers, dyes, surfactants, li-synthetic fibers, liaparo, chefo e bolaeang likokoanyana, meriana, monko o monate, li-additives tsa rabara le likokoanyana tse bolaeang likokoanyana.

1.Dye lipakeng
Naphthalene e phetha karolo ea bohlokoa tlhahisong ea dae, haholo-holo e le karolo e bohareng ea dae. Naphthalene ea indasteri ke thepa e tala ea bohlokoa bakeng sa ho etsa mefuta e fapaneng ea dae le mebala, joalo ka lidae tsa indigo le mebala e mosehla. Ho feta moo, naphthalene e ka fetoloa li-intermediate tsa dae joalo ka β-naphthol, tse sebelisoang hape ho hlahiseng lidae le mebala. Linaha tse fapaneng li na le likabelo tse fapaneng tsa tšebeliso ea naphthalene, empa li-intermediate tsa dae li lula li na le sebaka.
2.Li-additives tsa rabara
Naphthalene e sebelisoa haholo-holo joalo ka tlatsetso ts'ebetsong ea rabara. Tšebeliso ena e etsa karolo ea 15% ea kakaretso ea tšebeliso ea naphthalene. Li-additives tsa rabara li phetha karolo ea bohlokoa tlhahisong ea rabara. Ba ka ntlafatsa thepa ea rabara, joalo ka ho matlafatsa matla a eona, ductility kapa ho hanyetsa boemo ba leholimo. Joaloka motsoako oa rabara, naphthalene e fana ka mesebetsi le litšobotsi tse khethehileng ho lihlahisoa tsa rabara, e leng se etsang hore li tšoanelehe haholoanyane bakeng sa maemo a fapaneng a kopo.
3. Meriana e bolaeang likokoanyana
Naphthalene e na le ts'ebeliso e itseng tšimong ea chefo e bolaeang likokoanyana. Le hoja tšebeliso ea naphthalene e fapana ho ea ka linaha, meriana e bolaeang likokoanyana e etsa karolo ea 6 lekholong ea tšebeliso ea eona. Haholo-holo, linaheng tse ling, tse kang United States, karolo e sebelisoang ho hlahisa chefo e bolaeang likokoanyana e batla e le khōlō. Ho feta moo, anthracene e boetse e sebelisoa e le sebolaea-likokoanyana, e sebelisana le lisebelisoa tse ling tse kang lisebelisoa tsa luminescent le dae. Lisebelisoa tsena li bontša bohlokoa ba naphthalene le anthracene bakeng sa taolo ea likokoanyana temong le temong ea lirapa.
