I-beta naphthol

Izakhiwo Zamakhemikhali:

Ama-flakes amhlophe acwebezelayo noma impuphu emhlophe. Ayincibiliki emanzini, incibilika kalula ku-ethanol, i-ether, i-chloroform, i-glycerol kanye nezixazululo ze-alkali

Ukusetshenziswa

I-ethyl naphthol, eyaziwa nangokuthi i-β-naphthol kanye ne-2-naphthol, iyisithako esiphakathi kwe-naphthoxyacetic acid yokulawula ukukhula kwezitshalo. Iyinto ebalulekile eluhlaza ephilayo kanye ne-dye ephakathi. Isetshenziswa ekwenziweni kwe-tonic acid, i-butyric acid, i-β-naphthol-3-carboxylic acid, futhi isetshenziswa ekwenziweni kwama-antioxidants, i-DNP kanye namanye ama-antioxidants, imibala ephilayo kanye nokubulala amagciwane. Ama-ejenti, njll.

Indlela yokukhiqiza

Iwukulungiselela i-naphthalene ngokusebenzisa i-sulfonation kanye nokuncibilika kwe-alkali. Indlela ye-sulfonation alkali fusion iyindlela yokukhiqiza esetshenziswa kabanzi ekhaya nakwamanye amazwe, kodwa ihlushwa ukugqwala okukhulu, izindleko eziphezulu kanye nokusetshenziswa okuphezulu kwe-oxygen emanzini angcolile. Indlela ye-2-cumonaphthalene eyathuthukiswa yi-American Cyanamid Company isebenzisa i-naphthalene kanye ne-propylene Chemicalbook njengezinto zokusetshenziswa. Ngenkathi ikhiqiza i-2-naphthol, i-acetone ikhiqizwa njengomkhiqizo olandelanayo. Le ndlela ifana nendlela ye-cumene yokukhiqiza i-phenol. Isilinganiso sokusetshenziswa kwezinto zokusetshenziswa: i-naphthalene ehlanjululwe 1170kg/t, i-sulfuric acid 1080kg/t, i-solid caustic soda 700kg/t
