Naphthalene CAS 91-20-3
Naphthalene ndi kristalo wopanda mtundu, wonyezimira wa monoclinic. Ili ndi fungo lamphamvu la tarry. Ndi zophweka sublime pa firiji. Ndiwosungulumwa m'madzi, koma amasungunuka mu etha, ethanol, chloroform, carbon disulfide, benzene, ndi zina zotero. Amagwiritsidwa ntchito kwambiri popanga phthalic anhydride, naphthols zosiyanasiyana, naphthylamines, etc. Ndiwopakatikati popanga utomoni wopangira, plasticizers, utoto, surfactants, ulusi wopangira, zokutira, mankhwala ophera tizilombo, mankhwala, zonunkhira, zowonjezera mphira ndi mankhwala ophera tizilombo.
| Maonekedwe | Mtundu umodzi wokhotakhota wa kristalo wokhala ndi kuwala |

1.Dye zapakati
Naphthalene amagwira ntchito yofunika kwambiri popanga utoto, makamaka ngati utoto wapakati. Naphthalene ya mafakitale ndi chinthu chofunikira kwambiri popanga mitundu yosiyanasiyana ya utoto ndi utoto, monga utoto wa indigo ndi utoto wachikasu. Kuphatikiza apo, naphthalene imatha kusinthidwa kukhala zopangira utoto monga β-naphthol, zomwe zimagwiritsidwanso ntchito popanga utoto ndi utoto. Mayiko osiyanasiyana ali ndi magawo osiyanasiyana a ntchito za naphthalene, koma zopangira utoto nthawi zonse zimakhala ndi malo.
2.Zowonjezera za Rubber
Naphthalene amagwiritsidwa ntchito makamaka ngati chowonjezera pakukonza mphira. Kugwiritsiridwa ntchito kumeneku kumapanga pafupifupi 15% ya ntchito yonse ya naphthalene. Zowonjezera mphira zimagwira ntchito yofunika kwambiri pakupanga labala. Amatha kusintha mawonekedwe a rabara, monga kukulitsa mphamvu zake, ductility kapena kukana nyengo. Monga chowonjezera cha mphira, naphthalene imapereka magwiridwe antchito ndi mawonekedwe kuzinthu za rabara, zomwe zimawapangitsa kukhala oyenera pazogwiritsa ntchito zosiyanasiyana.
3. Mankhwala ophera tizilombo
Naphthalene ali ndi ntchito zina m'munda wa mankhwala ophera tizilombo. Ngakhale kuti kugwiritsa ntchito naphthalene kumasiyana m'mayiko osiyanasiyana, mankhwala ophera tizilombo amatenga pafupifupi 6% ya ntchito zake. Makamaka, m’maiko ena, monga ku United States, chiŵerengero chimene chimagwiritsidwa ntchito popanga mankhwala ophera tizilombo n’chachikulu ndithu. Kuphatikiza apo, anthracene imagwiritsidwanso ntchito ngati mankhwala ophera tizilombo, omwe amakhala limodzi ndi ntchito zina monga zida zowunikira komanso utoto. Ntchitozi zikuwonetsa kufunika kwa naphthalene ndi anthracene pakuwongolera tizirombo muulimi ndi ulimi wamaluwa.
