Katundu wa Mankhwala:

Zidutswa zoyera zonyezimira kapena ufa woyera. Wosasungunuka m'madzi, wosungunuka mosavuta mu ethanol, ether, chloroform, glycerol ndi alkali solutions

Kagwiritsidwe Ntchito

Ethyl naphthol, yomwe imadziwikanso kuti β-naphthol ndi 2-naphthol, ndi gawo la naphthoxyacetic acid yowongolera kukula kwa zomera. Ndi chinthu chofunikira kwambiri chachilengedwe komanso chopaka utoto. Chimagwiritsidwa ntchito popanga tonic acid, butyric acid, β-naphthol-3-carboxylic acid, ndipo chimagwiritsidwa ntchito popanga ma antioxidants, DNP ndi ma antioxidants ena, utoto wachilengedwe ndi kuyeretsa. Zothandizira, ndi zina zotero.

Njira yopangira

Ndi kukonzekera naphthalene kudzera mu sulfonation ndi alkali melting. Njira yopangira sulfonation alkali fusion ndi njira yopangira yomwe imagwiritsidwa ntchito kwambiri kunyumba ndi kunja, koma imavutika ndi dzimbiri lalikulu, mtengo wokwera komanso kugwiritsa ntchito mpweya wambiri wachilengedwe m'madzi otayira. Njira ya 2-cumonaphthalene yopangidwa ndi American Cyanamid Company imagwiritsa ntchito naphthalene ndi propylene Chemicalbook ngati zopangira. Popanga 2-naphthol, acetone imapangidwa ngati chowonjezera. Njirayi ndi yofanana ndi njira ya cumene yopangira phenol. Chiwerengero cha kugwiritsa ntchito zinthu zopangira: naphthalene yoyengedwa 1170kg/t, sulfuric acid 1080kg/t, solid caustic soda 700kg/t
