Nzira yekugadzira

Ndiyo yekugadzira naphthalene kuburikidza ne sulfonation uye alkali melting. Nzira ye sulfonation alkali fusion inzira yekugadzira inoshandiswa zvakanyanya munyika nekune dzimwe nyika, asi ine dambudziko rekuora kwakanyanya, inodhura zvakanyanya uye kushandisa oxygen yakawanda mumvura yakasviba. Nzira ye 2-cumonaphthalene yakagadzirwa neAmerican Cyanamid Company inoshandisa naphthalene ne propylene Chemicalbook sezvinhu zvekugadzira. Pakugadzira 2-naphthol, acetone inogadzirwa sechinhu chinobva pairi. Nzira iyi yakafanana nenzira ye cumene yekugadzira phenol.
