I-beta naphthol

Iipropati zeKhemikhali:

Iiflakes ezimhlophe ezikhazimlayo okanye umgubo omhlophe. Ayinyibiliki emanzini, inyibilika lula kwi-ethanol, i-ether, i-chloroform, i-glycerol kunye nezisombululo ze-alkali

Ukusetyenziswa

I-ethyl naphthol, ekwaziwa ngokuba yi-β-naphthol kunye ne-2-naphthol, sisixhobo esiphakathi kwe-naphthoxyacetic acid yokulawula ukukhula kwezityalo. Sisixhobo esibalulekileyo se-organic kunye ne-dye intermediate. Sisetyenziswa ekwenziweni kwe-tonic acid, i-butyric acid, i-β-naphthol-3-carboxylic acid, kwaye sisetyenziswa ekwenziweni kwe-antioxidants, i-DNP kunye nezinye ii-antioxidants, ii-pigment ze-organic kunye ne-sterilization. Iiarhente, njl.njl.

Indlela yemveliso

Yeyokulungiselela i-naphthalene ngokusebenzisa i-sulfonation kunye nokunyibilika kwe-alkali. Indlela ye-sulfonation alkali fusion yindlela yemveliso esetyenziswa kakhulu ekhaya nakwamanye amazwe, kodwa inengxaki yokubola okukhulu, iindleko eziphezulu kunye nokusetyenziswa kwe-oxygen ephezulu yebhayoloji emanzini amdaka. Indlela ye-2-cumonaphthalene eyenziwe yi-American Cyanamid Company isebenzisa i-naphthalene kunye ne-propylene Chemicalbook njengezinto eziluhlaza. Ngelixa ivelisa i-2-naphthol, i-acetone iveliswa njengemveliso engasemva. Le ndlela ifana nendlela ye-cumene yokwenza i-phenol. I-quota yokusetyenziswa kwezinto eziluhlaza: i-naphthalene ecociweyo eyi-1170kg/t, i-sulfuric acid eyi-1080kg/t, i-solid caustic soda eyi-700kg/t
