1. Toxicology yakafanana nephenol, uye inoparadza zvakanyanya. Kushungurudza zvakanyanya paganda. Inobatwa nyore nyore kuburikidza neganda. Toxic kutenderera kweropa uye itsvo. Mukuwedzera, inogona kukonzera kukanganisa kwekorneal. Kunyangwe huwandu hunouraya husingazivikanwe, kwave nezviitiko zvekufa kubva kune topical application ye3 kusvika 4g. Midziyo yekugadzira inofanirwa kunge yakavharwa uye isingabvire, uye inofanirwa kugezwa nenguva kana yakasaswa paganda. Maworkshops anofanirwa kupinzwa mhepo uye midziyo inofanira kunge isina mhepo. Vashandi vanofanira kupfeka giya rekudzivirira.

2. Inopisa, ruvara rwekuchengetedza kwenguva refu zvishoma nezvishoma rinova rakasviba, rakadzikama mumhepo, asi kana richinge rasangana nezuva zvishoma nezvishoma rinosviba. Sublimation nekudziya, nekushatisa phenol kunhuhwirira.

3. iripo mumhepo inoyerera. 4.

1. Yakaiswa mutsara nemasaga epurasitiki, masaga kana mabhegi akarukwa, net huremu 50kg kana 60kg pabhegi.

2. kuchengetedza uye kutakura kunofanira kunge kusina moto, unyoro-uchapupu, anti-exposure. Kuchengetwa munzvimbo yakaoma, ine mhepo. Chengetedza uye kutakura maererano nemirairo yezvinhu zvinopisa uye zvine chepfu.

Synthetic nzira

1. Inogadzirwa kubva naphthalene kuburikidza nesulfonation uye alkali kunyunguduka. Sulfonation alkali kunyunguduka inzira inoshandiswa nevakawanda kugadzirwa kumba nekune dzimwe nyika, asi ngura yakakomba, mutengo wakakwira uye mvura yetsvina biological oxygen yekushandisa yakakwira. Iyo 2-isopropylnaphthalene nzira yakagadzirwa neAmerican Cyanamid Company inotora naphthalene uye propylene seyakagadzirwa, uye inogadzira 2-naphthol uye acetone by-products panguva imwe chete, iyo yakafanana nenyaya ye phenol ne isopropylbenzene nzira. The raw material kushandiswa quota: 1170kg/t yakanaka naphthalene, 1080kg/t sulfuric acid, 700kg/t solid caustic soda.

2. Pisa iyo yakanyungudutswa yakachena naphthalene kusvika 140 ℃, ine chiyero chenaphthalene: sulfuric acid = 1: 1.085 (molar ratio), iyo sulfuric acid ye98% mu20min, uye sulfuric acid ye98% mu20min.

Mhedzisiro yacho ichapera kana zvirimo zve2-naphthalenesulfonic acid zvasvika pamusoro pe66% uye iyo acidity yese iri 25% -27%, ipapo iyo hydrolysis reaction ichaitwa pa160 ℃ kwe1h, naphthalenes yemahara ichapeperetswa nemhute yemvura. pa 140-150 ℃, uye ipapo hukama hwehukama hwe 1.14 naphthalenes huchawedzerwa zvishoma nezvishoma uye zvakaenzana pa80-90 ℃ mberi. Sodium sulfite mhinduro haina kucheneswa kudzamara iyo Congo red test bepa isingashanduke bhuruu. Kuita kwesarufa dioxide gasi inogadzirwa panguva yakakodzera nekubviswa kweutsi, zvigadzirwa zve neutralization zvakanyoroveswa kusvika ku35 ~ 40 ℃ makristasi ekutonhodza, achiyamwa makristasi kubva musefa ne10% mvura yemunyu, yakaoma, yakawedzerwa kune yakanyungudutswa ye98% sodium. hydroxide pa 300 ~ 310 ℃, ichikurudzira uye kuchengetedza 320 ~ 330 ℃, kuitira kuti sodium 2-naphthalene sulfonate base yakasanganiswa ne 2-naphthol sodium, uye wozoshandisa mvura inopisa kudzikisa chigadziko kunyunguduka, uye wozopfuura nepamusoro Neutralize the sulfur dioxide inogadzirwa nekuita, acidification reaction pa70 ~ 80 ℃ kusvika phenolphthalein isina ruvara. Zvigadzirwa zve acidification zvichange zvakamira zvakamira, iyo yekumusoro yemvura inopisa kusvika pakuvira, yakadzikama, yakakamurwa kuita aqueous layer, iyo isina kuchena chigadzirwa che2-naphthol yekutanga kupisa dehydration, uyezve decompression distillation, inogona kuve yakachena chigadzirwa.

3. Kubvisa uye crystallization nzira yekubvisa 1-naphthol mu 2-naphthol. Sanganisa 2-naphthol nemvura mune imwe chiyero uye kupisa kusvika 95 ℃, kana 2-naphthol yanyungudutswa, simbisa musanganiswa zvine simba uye udzikise tembiricha kusvika 85 ℃ kana zvakadaro, tonhodza chigadzirwa chekristalized slurry kusvika kukamuri tembiricha uye sefa. Izvo zviri mukati 1-naphthol inoteedzerwa nekuchena kuongororwa. 4.

Inogadzirwa kubva ku2-naphthalenesulfonic acid nealkali kunyunguduka [2].

Kuchengeta nzira
