1, 4-catechol o loʻo faʻaaogaina lautele e avea o se mea mataʻutia taua, sui vavalo ma fesoasoani i vailaʻau, vailaau faʻasaina, vali ma paʻu, e masani ona faʻaaogaina i le atinaʻeina o sui, vali anthraquinone, vali azo, paʻu anti-matua sui ma monomer polymerization inhibitor, meaʻai. faʻamautu ma faʻapipiʻiina le antioxidant, anticoagulant suauʻu, faʻamalosi ammonia faʻapipiʻi ma isi.O le Hydroquinone e masani ona faʻaaogaina e avea o se atinaʻe i ata.Hydroquinone ma ona alkylates e masani ona faʻaaogaina e pei o polymer-blocking agents faʻaopoopo i le faagasologa o le teuina o le monomer ma felauaiga, ma o le faʻaogaina masani e tusa ma le 200ppm.O le hydroquinone monomethyl ether o le vaeluagalemu lea o le suauu taumafa antioxidant BHA.Benzene Chemicalbook dimethyl ether o le vaeluagalemu lea o vali, pigments faʻaletino ma mea manogi;O le Hydroquinone diethyl ether o le vaeluagalemu lea o le pa'u ma le vali.Hydroquinone e faʻaaogaina foi i le sauniuniga o le N, N'-diphenyl-p-phenylenediamine, e faʻaaogaina i le paʻu ma le penisini antioxidant ma deodorant.O le hydroquinone na gaosia i le auala aniline muamua, ma o le taimi nei o le gaosiga o fale gaosi oloa ua atiaʻe foi le catechol co-production, isopropylbenzene ma le bisphenol A metotia.O loʻo faʻaaogaina pea le auala Aniline i Saina.1. Aniline na oxidized i benzoquinone e manganese dioxide i sulfuric acid medium, ona faaitiitia i le hydroquinone e uʻamea pauta.A maeʻa le faʻatonuga, decolorization, crystallization, faʻamago oloa maeʻa.Industrial grade hydroquinone Chemicalbook content ≥99%, ata pue ≥99.5%.Fa'atauga o mea taumafa mata: aniline 1250kg/t, sulfuric acid (93%) 5500kg/t, pyrolusite pa'u (e aofia ai manganese dioxide 60-65%) 5950kg/t, pa'u u'amea (e iai Fe≥90%) 540kg/t.2. Nitrobenzene e pei o mea mata, ina ua uma le hydrogenation, faiga faʻavevela.
