Ubume kunye nokuzinza

hlela

1. I-Toxicology ifana ne-phenol, kwaye i-corrosive enamandla.Ukucaphukisa kakhulu ulusu.Ifunxwa lula ngesikhumba.Ityhefu kumjikelezo wegazi kunye nezintso.Ukongeza, kunokubangela umonakalo we-cornea.Nangona inani elibulalayo lingaziwa, kukho iimeko zokufa kwi-topical application ye-3 ukuya kwi-4g.Izixhobo zokuvelisa kufuneka zitywinwe kwaye zingavuzi, kwaye kufuneka zihlanjwe ngexesha elifanelekileyo ukuba zitshizwe esikhumbeni.Iindibano zocweyo kufuneka zifakwe umoya kwaye izixhobo kufuneka zingangeni moya.Abanini-zithuthi kufuneka banxibe izixhobo zokukhusela.

2. Ukutsha, umbala wogcino olude ngokuthe ngcembe uba mnyama, uzinzile emoyeni, kodwa xa ujongwe elangeni ngokuthe ngcembe ube mnyama.I-sublimation ngokufudumeza, kunye nephunga elimnandi le-phenol.

3. ekhoyo kwi-flue gas.4.

4. isisombululo samanzi sijika sibe luhlaza kunye ne-ferric chloride [1].

Indlela yokugcina

hlela

1. Kufakwe iingxowa zeplastiki, iingxowa okanye iingxowa ezilukiweyo, ubunzima be net 50kg okanye 60kg ingxowa nganye.

2. ukugcinwa kunye nokuthutha kufuneka kungabi nomlilo, umswakama-ubungqina, ukuchasana ne-exposure.Igcinwe kwindawo eyomileyo, nengena umoya.Gcina kwaye uhambise ngokwemigaqo yezinto ezinokutsha kunye netyhefu.

Indlela yokwenziwa

hlela

1. Yenziwe kwi-naphthalene nge-sulfonation kunye nokunyibilika kwe-alkali.Ukunyibilika kwe-alkali ye-sulfonation yindlela esetyenziswa ngokubanzi kwimveliso yasekhaya nakwamanye amazwe, kodwa umhlwa unzulu, ixabiso liphezulu kwaye ukusetyenziswa kwamanzi amdaka kuphezulu.Indlela ye-2-isopropylnaphthalene ephuhliswe yiNkampani yaseMelika yeCyanamid ithatha i-naphthalene kunye nepropylene njengezinto ezibonakalayo, kwaye ivelise i-2-naphthol kunye ne-acetone nge-acetone ngexesha elifanayo, elifana nemeko ye-phenol nge-isopropylbenzene indlela.I-quota yokusetyenziswa kwezinto ekrwada: 1170kg/t i-naphthalene entle, i-1080kg/t sulfuric acid, i-700kg/t eyomeleleyo ye-caustic soda.

2. Ukushisa i-naphthalene ecocekileyo etyhidiweyo kwi-140 ℃, kunye nomlinganiselo we-naphthalene: i-sulfuric acid = 1: 1.085 (i-molar ratio), i-asidi ye-sulfuric ye-98% kwi-20min, kunye ne-asidi ye-sulfuric ye-98% kwi-20min.

Ukusabela kuya kuphela xa umxholo we-2-naphthalenesulfonic acid ufikelela ngaphezu kwe-66% kwaye i-acidity iyonke yi-25% -27%, emva koko impendulo ye-hydrolysis iya kuqhutywa kwi-160 ℃ ye-1h, i-naphthalenes yamahhala iya kubethwa ngumphunga wamanzi. kwi-140-150 ℃, kwaye ke ukuxinana kwe-1.14 naphthalenes kuya kongezwa ngokucothayo nangokulinganayo kwi-80-90 ℃ kwangaphambili.Isisombululo se-sodium sulfite singathathi hlangothi de iphepha lokuvavanya elibomvu laseCongo lingatshintshi blue.Ukusabela kwegesi yesulfure dioxide eyenziwe ngexesha elifanelekileyo ngokususwa komphunga, iimveliso zokungathathi hlangothi zipholile ukuya kuma-35 ~ 40 ℃ iikristale zokupholisa, ukufunxa iikristale kwisihluzo kunye ne-10% yamanzi etyuwa, yomile, yongezwa kwimeko etyhidiweyo ye-98% yesodium. hydroxide kwi 300 ~ 310 ℃, ukuxhokonxa nokugcina 320 ~ 330 ℃, ukuze sodium 2-naphthalene sulfonate base idityaniswe 2-naphthol sodium, uze usebenzise amanzi ashushu ukunyibilika isiseko ukunyibilika, uze udlulele ngasentla Neutralize I-sulphur dioxide eveliswa yi-reaction, i-acidification reaction kwi-70 ~ 80 ℃ de i-phenolphthalein ingenambala.Iimveliso acidification ziya kuba layering static, umaleko ophezulu ulwelo ifudunyezwe ukuba abilayo, static, yahlulwe umaleko aqueous, imveliso ekrwada 2-naphthol kuqala dehydration eshushu, kwaye ke decompression distillation, inokuba yimveliso ecocekileyo.

3. Indlela yokukhupha kunye ne-crystallization yokususa i-1-naphthol kwi-2-naphthol.Xuba i-2-naphthol kunye namanzi kumlinganiselo othile kunye nobushushu ukuya kwi-95 ℃, xa i-2-naphthol inyibilika, xuba umxube ngamandla kwaye unciphise ubushushu ukuya kwi-85 ℃ okanye kunjalo, upholise imveliso ye-crystallized slurry kwiqondo lokushisa kunye nesihlungi.Umxholo we-1-naphthol unokulandeleka ngokuhlalutya ubunyulu.4.

Iveliswa kwi-2-naphthalenesulfonic acid ngokunyibilika kwe-alkali [2].

Sebenzisa

hlela

1. Izinto ezibalulekileyo ze-organic raw and dye intermediates, ezisetyenziselwa ukuveliswa kwe-tartaric acid, i-butyric acid, i-β-naphthol-3-carboxylic acid, kwaye isetyenziswe ekwenzeni i-antioxidant butyl, i-antioxidant DNP kunye nezinye i-antioxidants, i-pigments eziphilayo kunye nefungicides.

2. Isetyenziswe njenge-reagent yokuzimisela kwe-sulfonamide kunye ne-amines enevumba elimnandi nge-chromatography.Ikwasetyenziswa kwi-organic synthesis.

3. Isetyenziselwa ukuphucula i-cathodic polarization, ukucoca i-crystallization kunye nokunciphisa ubungakanani bepore kwi-acidic tin plating.Ngenxa yobume be-hydrophobic yale mveliso, umxholo ogqithisileyo uya kubangela i-gelatin condensation kunye nemvula, okubangelwa yimivimbo kwi-plating.

4. Ikakhulu isetyenziselwa ukuveliswa kwe-asidi e-orenji Z, i-acid e-orenji II, i-acid emnyama i-ATT, i-acid mordant emnyama T, i-acid mordant emnyama A, i-acid mordant emnyama R, i-acid complex pink B, i-acid complex ebomvu ebomvu BRRW, i-acid complex black WAN , umbala phenol AS, umbala phenol AS-D, umbala phenol AS-OL, umbala phenol AS-SW, iorenji esebenzayo eqaqambileyo X-GN, i-orenji esebenzayo ekhanyayo K-GN, ebomvu esebenzayo K-1613, ebomvu esebenzayo K-1613, esebenzayo i-orenji ekhanyayo i-X-GN, i-orenji esebenzayo ekhanyayo i-K-GN.I-Neutral Purple BL, i-Neutral Black BGL, i-Blue Copper yeTyuwa eNgqongileyo 2R, i-Sunlight Resistant Blue B2PL, iBlue RG eNgqongileyo, iRW eBlue kunye nezinye iidayi [2].
