1. Toxicology ndi yofanana ndi phenol, ndipo imawononga kwambiri. Zokwiyitsa kwambiri pakhungu. Imatengeka mosavuta kudzera pakhungu. Poizoni ku magazi ndi impso. Kuphatikiza apo, imatha kuyambitsa kuwonongeka kwa cornea. Ngakhale kuchuluka kwakupha sikudziwika, pakhala pali milandu yakufa chifukwa chogwiritsa ntchito pamutu pa 3 mpaka 4g. Zida zopangira ziyenera kusindikizidwa komanso kuti zisatayike, ndipo ziyenera kutsukidwa nthawi yake ngati zitawazidwa pakhungu. Malo ogwirira ntchito akuyenera kukhala ndi mpweya wabwino ndipo zida ziyenera kukhala zopumira. Oyendetsa ayenera kuvala zida zoteteza.

2. Choyaka, mtundu wa kusungirako kwautali pang'onopang'ono umakhala wakuda, wokhazikika mumlengalenga, koma ukakhala padzuwa pang'onopang'ono umakhala mdima. Sublimation ndi Kutentha, ndi fungo losasangalatsa la phenol.

3. alipo mu mpweya wa flue. 4.

1. Akutidwa ndi matumba apulasitiki, matumba kapena matumba oluka, kulemera kwa ukonde 50kg kapena 60kg pa thumba.

2. kusungirako ndi zoyendetsa ziyenera kukhala zosawotcha, zotetezedwa ndi chinyezi, zotsutsana ndi zowonongeka. Kusungidwa mu youma, mpweya wokwanira malo. Sungani ndi kunyamula motsatira malamulo a zinthu zoyaka ndi poizoni.

 

Njira yopangira

sinthani

1. Amapangidwa kuchokera ku naphthalene kupyolera mu sulfonani ndi kusungunuka kwa alkali. Kusungunuka kwa sulfonation alkali ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga kunyumba ndi kunja, koma dzimbiri ndizovuta, mtengo wake ndi wokwera komanso kugwiritsa ntchito kwa okosijeni wamadzi otayira ndikokwera kwambiri. Njira ya 2-isopropylnaphthalene yopangidwa ndi American Cyanamid Company imatenga naphthalene ndi propylene monga zopangira, ndipo imapanga 2-naphthol ndi acetone by-products nthawi yomweyo, zomwe zimafanana ndi nkhani ya phenol ndi isopropylbenzene njira. The zopangira mowa kuchuluka: 1170kg/t zabwino naphthalene, 1080kg/t sulfuric acid, 700kg/t olimba caustic soda.

2. Kutenthetsa naphthalene koyera wosungunuka mpaka 140 ℃, ndi chiŵerengero cha naphthalene: sulfuric acid = 1: 1.085 (molar ratio), sulfuric acid 98% mu 20min, ndi sulfuric acid 98% mu 20min.

Zomwezo zidzatha pamene 2-naphthalenesulfonic acid ifika pamwamba pa 66% ndipo acidity yonse ndi 25% -27%, ndiye kuti hydrolysis idzachitika pa 160 ℃ kwa 1h, naphthalenes yaulere idzawomberedwa ndi nthunzi yamadzi. pa 140-150 ℃, ndiyeno kachulukidwe wachibale wa 1.14 naphthalenes adzawonjezedwa pang'onopang'ono ndi wogawana pa 80-90 ℃ pasadakhale. Sodium sulfite solution imasinthidwa mpaka pepala lofiira la Congo silisintha buluu. Zochita za sulfure dioxide mpweya kwaiye m'nthawi yake ndi kuchotsa nthunzi, neutralization mankhwala utakhazikika kwa 35 ~ 40 ℃ kuzirala makhiristo, kuyamwa makhiristo fyuluta ndi 10% madzi amchere, youma, anawonjezera kusungunuka 98% sodium. hydroxide pa 300 ~ 310 ℃, oyambitsa ndi kusunga 320 ~ 330 ℃, kuti sodium 2-naphthalene sulfonate m'munsi anasakaniza kuti 2-naphthol sodium, ndiyeno ntchito madzi otentha kuchepetsa m'munsi Sungunulani, ndiyeno kudutsa pamwamba Neutralize sulfure woipa wopangidwa ndi anachita, acidification anachita pa 70 ~ 80 ℃ mpaka phenolphthalein anali colorless. The mankhwala acidification adzakhala malo amodzi layering, chapamwamba wosanjikiza wa madzi usavutike mtima kuti otentha, malo amodzi, ogaŵikana amadzimadzi wosanjikiza, yaiwisi mankhwala a 2-naphthol woyamba mkangano madzi m`thupi, ndiyeno decompression distillation, akhoza kukhala wangwiro mankhwala.

3. Njira yochotsera ndi crystallization kuchotsa 1-naphthol mu 2-naphthol. Sakanizani 2-naphthol ndi madzi mu gawo lina ndi kutentha kwa 95 ℃, pamene 2-naphthol imasungunuka, yambitsani kusakaniza mwamphamvu ndikuchepetsa kutentha kwa 85 ℃ kapena kotero, kuziziritsa mankhwala opangidwa ndi crystallized slurry kutentha ndi fyuluta. Zomwe zili mu 1-naphthol zimatsatiridwa ndi kusanthula koyera. 4.

Amapangidwa kuchokera ku 2-naphthalenesulfonic acid ndi kusungunuka kwa alkali [2].

 

Njira yosungira

1. Akutidwa ndi matumba apulasitiki, matumba kapena matumba oluka, kulemera kwa ukonde 50kg kapena 60kg pa thumba.

2. kusungirako ndi zoyendetsa ziyenera kukhala zosawotcha, zotetezedwa ndi chinyezi, zotsutsana ndi zowonongeka. Kusungidwa mu youma, mpweya wokwanira malo. Sungani ndi kunyamula motsatira malamulo a zinthu zoyaka ndi poizoni.

 

Gwiritsani ntchito

1. Zida zofunikira za organic ndi zopangira utoto, zomwe zimagwiritsidwa ntchito popanga tartaric acid, butyric acid, β-naphthol-3-carboxylic acid, ndipo zimagwiritsidwa ntchito popanga antioxidant butyl, antioxidant DNP ndi antioxidants ena, organic pigments ndi fungicides.

2. Ntchito ngati reagent kwa mtima wa sulfonamide ndi onunkhira amines ndi woonda wosanjikiza chromatography. Amagwiritsidwanso ntchito popanga organic synthesis.

3. Amagwiritsidwa ntchito kukonza polarization ya cathodic, kuyenga crystallization ndi kuchepetsa kukula kwa pore mu plating acidic malata. Chifukwa cha chikhalidwe cha hydrophobic cha mankhwalawa, kuchuluka kwambiri kumayambitsa gelatin condensation ndi mpweya, zomwe zimabweretsa mikwingwirima mu plating.

4. Makamaka ntchito kupanga asidi lalanje Z, asidi lalanje II, asidi wakuda ATT, asidi mordant wakuda T, asidi mordant wakuda A, asidi mordant wakuda R, asidi zovuta pinki B, asidi zovuta wofiira bulauni BRRW, asidi zovuta wakuda WAN , mtundu phenol AS, mtundu phenol AS-D, mtundu phenol AS-OL, mtundu phenol AS-SW, yogwira yowala lalanje X-GN, yogwira yowala lalanje K-GN, yogwira wofiira K-1613, yogwira wofiira K-1613, yogwira kuwala lalanje X-GN, yogwira yowala lalanje K-GN. Neutral Purple BL, Neutral Black BGL, Direct Copper Salt Blue 2R, Direct Sunlight Resistant Blue B2PL, Direct Blue RG, Direct Blue RW ndi mitundu ina [2].
