Mawu Oyamba

Cresol, yomwe imadziwika kuti methylphenol (dzina lachingerezi Cresol), ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha p-toluenol:

Ubwino:

Maonekedwe: Cresol ndi madzi opanda mtundu kapena achikasu okhala ndi fungo lapadera la phenolic.

Kusungunuka: Kusungunuka mu mowa, ethers ndi ethers, komanso kusungunuka pang'ono m'madzi.

Chemical properties: Cresol ndi chinthu cha acidic chomwe chimagwirizana ndi alkali kupanga mchere wofanana.

Gwiritsani ntchito:

Kugwiritsa ntchito m'mafakitale: Cresol imagwiritsidwa ntchito ngati chosungira, mankhwala ophera tizilombo, komanso osungunulira popanga zoteteza. Imagwiranso ntchito ngati chothandizira komanso chosungunulira m'mafakitale a rabara ndi utomoni.

Ntchito zaulimi: Toluene atha kugwiritsidwa ntchito paulimi ngati mankhwala ophera tizilombo komanso fungicide.

Njira:

Pali njira zambiri zopangira toluenol, imodzi yomwe imagwiritsidwa ntchito kwambiri kuti ipezeke kudzera mu ma oxidation reaction ya toluene. Gawo lenileni ndiloti muyambe kuchitapo kanthu toluene ndi mpweya kuti mupange toluol pansi pa chothandizira.

Zambiri Zachitetezo:

Cresol ndi poizoni, ndipo kukhudzana mwachindunji kapena kupuma mpweya wambiri wa cresol kungakhale kovulaza thanzi. Njira zoyendetsera chitetezo ziyenera kutsatiridwa zikagwiritsidwa ntchito, ndipo zida zodzitetezera ziyenera kugwiritsidwa ntchito.

Pewani kukhudzana ndi khungu nthawi yayitali komanso kupewa kutulutsa nthunzi yake.

Posungira ndikugwira toluenol, iyenera kusindikizidwa bwino ndikusungidwa kutali ndi kuyatsa ndi kutentha kwakukulu.
