Beta naphthol

Nā Waiwai Kemika:

Nā ʻāpana keʻokeʻo ʻālohilohi a i ʻole ka pauka keʻokeʻo. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe maʻalahi i ka ethanol, ether, chloroform, glycerol a me nā hopena alkali

Hoʻohana

ʻO Ethyl naphthol, i ʻike ʻia hoʻi ʻo β-naphthol a me 2-naphthol, he waena ia o ka mea hoʻoponopono ulu mea kanu naphthoxyacetic acid. He mea maka organik koʻikoʻi a me ka waena o ka dye. Hoʻohana ʻia ia i ka hana ʻana o ka waikawa tonic, ka waikawa butyric, ka waikawa β-naphthol-3-carboxylic, a hoʻohana ʻia i ka hana ʻana o nā antioxidants, DNP a me nā antioxidants ʻē aʻe, nā pigments organik a me ka sterilization. Nā ʻelele, a pēlā aku.

ʻO ke ʻano hana

ʻO ia ke hoʻomākaukau ʻana i ka naphthalene ma o ka sulfonation a me ka hoʻoheheʻe ʻana o ka alkali. ʻO ke ʻano hana sulfonation alkali fusion kahi ʻano hana i hoʻohana nui ʻia ma ka home a ma waho, akā ua pilikia ia i ka pala nui, ke kumukūʻai kiʻekiʻe a me ka hoʻohana ʻana i ka oxygen olaola kiʻekiʻe o ka wai hoʻoneoneo. ʻO ke ʻano 2-cumonaphthalene i hoʻomohala ʻia e ka American Cyanamid Company e hoʻohana i ka naphthalene a me ka propylene Chemicalbook ma ke ʻano he mea maka. I ka wā e hana ana i ka 2-naphthol, hana ʻia ka acetone ma ke ʻano he huahana ʻaoʻao. Ua like kēia ʻano hana me ke ʻano cumene no ka hana ʻana i ka phenol. Ka nui o ka hoʻohana ʻana i nā mea maka: naphthalene i hoʻomaʻemaʻe ʻia 1170kg/t, sulfuric acid 1080kg/t, solid caustic soda 700kg/t
