Naphthalene CAS 91-20-3
Naphthalene ikristaro isina ruvara, inopenya monoclinic. Iine kunhuhwirira kwakasimba kwetarry. Zviri nyore kuti sublime pakamuri tembiricha. Hainyungudike mumvura, asi inonyungudika muether, ethanol, chloroform, carbon disulfide, benzene, etc. Naphthalene ndiyo inonyanya kukosha condensed hydrocarbon in industry. Inonyanya kushandiswa kugadzira phthalic anhydride, zvakasiyana-siyana naphthols, naphthylamines, nezvimwewo. Iri pakati pekugadzirwa kwemashizha ekugadzira, plasticizers, dhayi, surfactants, synthetic fibers, coatings, pesticides, mishonga, zvinonhuwira, rubber additives uye mishonga yezvipembenene.

1.Dye pakati
Naphthalene inoita basa rakakosha mukugadzira dhayi, kunyanya seyepakati dhayi. Indasitiri naphthalene chinhu chakakosha mbishi chekugadzira akasiyana dhayi uye pigment, senge indigo dhayi uye yero pigment. Uye zvakare, naphthalene inogona kushandurwa kuita dhayi yepakati senge β-naphthol, iyo inoshandiswa zvakare mukugadzira dhayi uye pigment. Nyika dzakasiyana dzine migove yakasiyana yekushandiswa kwenaphthalene, asi dhayi dzepakati dzinogara dziine nzvimbo.
2.Rubber additives
Naphthalene inonyanya kushandiswa sechinhu chinowedzera mukugadzirisa rabha. Kushandiswa uku kunotora chikamu che15% chekushandiswa kwese kwenaphthalene. Rubber additives anoita basa guru mukugadzirwa kwerabha. Vanogona kuvandudza zvimiro zverabha, sekusimudzira simba rayo, ductility kana kuramba kwemamiriro ekunze. Sekuwedzera kwerabha, naphthalene inopa chaiwo mabasa uye hunhu kune zvigadzirwa zverabha, zvichiita kuti zvive zvakanyanya kukodzera kune akasiyana maficha ekushandisa.
3. Mishonga yezvipembenene
Naphthalene ine zvimwe zvinoshandiswa mumunda wemishonga yezvipembenene. Kunyange zvazvo kushandiswa kwenaphthalene kuchisiyana munyika nenyika, mishonga inouraya zvipembenene inosvika 6% yekushandiswa kwayo. Kunyanya, mune dzimwe nyika, dzakadai seUnited States, chikamu chinoshandiswa kugadzira mishonga yezvipembenene chakakura. Pamusoro pezvo, anthracene inoshandiswawo semushonga wezvipembenene, uchigara pamwe nezvimwe zvinoshandiswa senge zvinhu zvinopenya uye dhayi. Aya maapplication anoratidza kukosha kwenaphthalene neanthracene pakudzora tupukanana mune zvekurima uye horticulture.
