1. Kupha poizoni kumafanana ndi phenol, ndipo ndi chinthu chowononga kwambiri. Chimakwiyitsa kwambiri khungu. Chimalowa mosavuta kudzera pakhungu. Ndi poizoni ku magazi ndi impso. Kuphatikiza apo, chingayambitse kuwonongeka kwa cornea. Ngakhale kuti kuchuluka kwa imfa sikudziwika, pakhala pali milandu ya imfa chifukwa chogwiritsa ntchito 3 mpaka 4g pamwamba. Zipangizo zopangira ziyenera kutsekedwa komanso kusatulutsa madzi, ndipo ziyenera kutsukidwa nthawi yomweyo ngati zitathiridwa pakhungu. Malo ogwirira ntchito ayenera kukhala ndi mpweya wokwanira ndipo zida ziyenera kukhala zopanda mpweya. Ogwira ntchito ayenera kuvala zida zodzitetezera.

2. Yoyaka, mtundu wa kusungidwa kwa nthawi yayitali umakhala wakuda pang'onopang'ono, wokhazikika mlengalenga, koma ikawonekera padzuwa pang'onopang'ono imakhala yakuda. Kutenthedwa ndi kutentha, ndi fungo loyipa la phenol.

3. mpweya wotuluka m'chimbudzi umapezeka mu mpweya wotuluka m'chimbudzi.

4. yankho lamadzi limasanduka lobiriwira ndi ferric chloride [1].

Njira yosungira

1. Amapangidwa kuchokera ku naphthalene kudzera mu sulfonation ndi alkali melting. Sulfonation alkali melting ndi njira yogwiritsidwa ntchito kwambiri popanga zinthu kunyumba ndi kunja, koma dzimbiri lake ndi lalikulu, mtengo wake ndi wokwera ndipo madzi otayira amamwa okosijeni ambiri. Njira ya 2-isopropylnaphthalene yopangidwa ndi American Cyanamid Company imatenga naphthalene ndi propylene ngati zopangira, ndipo imapanga 2-naphthol ndi acetone by-products nthawi imodzi, zomwe zimafanana ndi njira ya phenol ndi isopropylbenzene. Chiwerengero cha kugwiritsa ntchito zinthu zopangira: 1170kg/t fine naphthalene, 1080kg/t sulfuric acid, 700kg/t solid caustic soda.

2. Tenthetsani naphthalene yosungunuka bwino mpaka 140℃, ndi chiŵerengero cha naphthalene:sulfuric acid = 1:1.085 (molar ratio), sulfuric acid ya 98% mu mphindi 20, ndi sulfuric acid ya 98% mu mphindi 20.

Kuchitapo kanthu kudzatha pamene kuchuluka kwa 2-naphthalenesulfonic acid kufika pamwamba pa 66% ndipo asidi yonse ndi 25%-27%, ndiye kuti hydrolysis reaction idzachitika pa 160℃ kwa ola limodzi, ma naphthalenes omasuka adzachotsedwa ndi nthunzi ya madzi pa 140-150℃, kenako kuchuluka kwa 1.14 naphthalenes kudzawonjezedwa pang'onopang'ono komanso mofanana pa 80-90℃ pasadakhale. Sodium sulfite solution imachotsedwa mpaka pepala loyesera lofiira la Congo lisasinthe buluu. Pamene mpweya wa sulfure dioxide umatulutsidwa nthawi yomweyo, zinthu zoletsa kuzizira zimazizira kufika pa 35 ~ 40 ℃, kuyamwa makhiristo kuchokera ku fyuluta ndi madzi amchere 10%, ouma, onjezedwa ku 98% sodium hydroxide pa 300 ~ 310 ℃, kusakaniza ndi kusunga 320 ~ 330 ℃, kotero kuti sodium 2-naphthalene sulfonate base isakanizidwe ndi sodium 2-naphthol, kenako kugwiritsa ntchito madzi otentha kuti achepetse kusungunuka kwa maziko, kenako kupitirira mu izi. Chotsani sulfure dioxide yopangidwa ndi zomwe zimachitika, acidification reaction pa 70 ~ 80 ℃ mpaka phenolphthalein itakhala yopanda utoto. Zinthu zoletsa kuzizira zidzakhala zokhazikika, gawo lapamwamba la madzi limatenthedwa mpaka kuwira, lokhazikika, logawidwa m'madzi oundana, mankhwala osaphika a 2-naphthol amatenthedwa poyamba, kenako decompression distillation, akhoza kukhala mankhwala oyera.

3. Njira yochotsera ndi kuyika makristalo kuti muchotse 1-naphthol mu 2-naphthol. Sakanizani 2-naphthol ndi madzi muyeso winawake ndikutentha mpaka 95℃, 2-naphthol ikasungunuka, sakanizani chisakanizocho mwamphamvu ndikuchepetsa kutentha kufika pa 85℃ kapena apo, ziziritsani slurry yopangidwa ndi makristalo kutentha kwa chipinda ndikusefa. Zomwe zili mu 1-naphthol zimatha kutsatiridwa ndi kusanthula kwa kuyera. 4.

Amapangidwa kuchokera ku 2-naphthalenesulfonic acid kudzera mu alkali melting [2].
