Beta naphthol

Meatotino Fa'akemikolo:

Pa'epa'e pupula pe pa'u pa'epa'e. E le solo i le vai, faigofie ona solo i le ethanol, ether, chloroform, glycerol ma vaila'au alkali.

Fa'aaogāga

O le Ethyl naphthol, e ta'ua fo'i o le β-naphthol ma le 2-naphthol, o se vaila'au fa'asolosolo o le naphthoxyacetic acid e fa'atonutonu ai le tuputupu a'e o la'au. O se mea mata taua fa'alenatura ma se vaila'au fa'asolosolo. E fa'aaogaina i le gaosiga o le tonic acid, butyric acid, β-naphthol-3-carboxylic acid, ma fa'aaogaina i le gaosiga o antioxidants, DNP ma isi antioxidants, pigments fa'alenatura ma le fa'amama. O vaila'au, ma isi.

O le auala e gaosia ai

O le saunia lea o le naphthalene e ala i le sulfonation ma le alkali melting. O le metotia o le sulfonation alkali fusion o se metotia gaosiga e faʻaaogaina lautele i totonu ma fafo atu o le atunuʻu, ae e aʻafia i le ele tele, tau maualuga ma le tele o le faʻaaogaina o le okesene faʻalenatura o otaota. O le metotia 2-cumonaphthalene na atiaʻe e le American Cyanamid Company e faʻaaogaina le naphthalene ma le propylene Chemicalbook o ni mea mata. Aʻo gaosia le 2-naphthol, e gaosia le acetone o se oloa faʻaopoopo. O lenei metotia e tutusa ma le metotia cumene mo le gaosia o le phenol. Faʻasologa o mea mata e faʻaaogaina: naphthalene faʻamamaina 1170kg/t, sulfuric acid 1080kg/t, solid caustic soda 700kg/t
