Naphthalene CAS 91-20-3
ʻO ka Naphthalene he aniani monoclinic ʻālohilohi ʻole. He honi maloo ikaika kona. He mea maʻalahi ka sublime ma ka lumi wela. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, akā hiki ke hoʻoheheʻe ʻia i ka ether, ethanol, chloroform, carbon disulfide, benzene, a pēlā aku. Hoʻohana nui ia e hana i ka phthalic anhydride, nā naphthols like ʻole, nā naphthylamines, etc.

1.Dye intermediates
He kuleana koʻikoʻi ka Naphthalene i ka hana ʻana i ka wai, ʻoi aku ka nui ma ke ʻano he waena waena. He mea koʻikoʻi ka naphthalene ʻoihana no ka hana ʻana i nā mea pena like ʻole a me nā puaʻa, e like me nā wai indigo a me nā pua melemele. Eia kekahi, hiki ke hoʻololi ʻia ka naphthalene i loko o nā intermediates dye e like me β-naphthol, i hoʻohana hou ʻia i ka hana ʻana i nā mea pena a me nā puaʻa. He ʻokoʻa ko nā ʻāina like ʻole i ka hoʻohana ʻana i ka naphthalene, akā loaʻa mau nā wahi waena o ka wai.
2. Rubber mea hoʻohui
Hoʻohana nui ʻia ʻo Naphthalene ma ke ʻano he mea hoʻohui i ka hana ʻana i ka lāʻau. ʻO kēia hoʻohana ʻana ma kahi o 15% o ka nui o ka hoʻohana ʻana i ka naphthalene. Pāʻani koʻikoʻi nā mea hoʻohui Rubber i ka hana ʻana i ka lāʻau. Hiki iā lākou ke hoʻomaikaʻi i nā waiwai o ka lāʻau, e like me ka hoʻonui ʻana i kona ikaika, ductility a i ʻole ka pale ʻana i ka wā. Ma ke ʻano he mea hoʻohui lāʻau, hāʻawi ka naphthalene i nā hana kikoʻī a me nā hiʻohiʻona i nā huahana lāʻau, e ʻoi aku ka kūpono no nā hiʻohiʻona noi.
3. Nā lāʻau lapaʻau
Loaʻa i ka Naphthalene kekahi mau hoʻohana ʻana i ke kahua o nā insecticides. ʻOiai ʻokoʻa ka hoʻohana ʻana i ka naphthalene mai kēlā ʻāina a i kēia ʻāina, ʻoi aku ka nui o nā insecticides ma kahi o 6% o kāna hoʻohana ʻana. ʻO ka mea nui, ma kekahi mau ʻāina, e like me ʻAmelika Hui Pū ʻIa, ʻoi aku ka nui o ka hapa i hoʻohana ʻia e hana i nā insecticides. Eia kekahi, hoʻohana pū ʻia ka anthracene ma ke ʻano he insecticide, e noho pū ana me nā mea hoʻohana ʻē aʻe e like me nā mea luminescent a me nā mea pena. Hōʻike kēia mau noi i ke koʻikoʻi o ka naphthalene a me ka anthracene no ka mālama ʻana i nā pest i ka mahiʻai a me ka horticulture.
