Nhanganyaya

Cresol, kemikari inozivikanwa se methylphenol (zita rechirungu rekuti Cresol), musanganiswa weorganic. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza p-toluenol:

Hunhu:

Chitarisiko: Cresol imvura isina ruvara kana yero ine yakakosha phenolic hwema.

Solubility: Inonyungudika mudoro, ethers uye ethers, uye inonyungudika zvishoma mumvura.

Chemical properties: Cresol chinhu chine acidic chinopindirana nealkali kugadzira munyu unoenderana.

Shandisa:

Mashandisirwo eindasitiri: Cresol inoshandiswa seyakachengetedza, inouraya utachiona, uye inonyungudutsa mukugadzira zvinochengetedza. Iyo inoshandawo sechinhu chinokonzeresa uye chinonyungudutsa mumaindasitiri erabha uye resin.

Kushandiswa kwekurima: Toluene inogona kushandiswa muchikamu chekurima semushonga wezvipembenene uye fungicide.

Nzira:

Kune nzira dzakawanda dzekugadzira toluenol, imwe yacho inowanzoshandiswa kuiwana kuburikidza nekuita oxidation ye toluene. Nhanho chaiyo ndeyekutanga kuita toluene neokisijeni kuti ibudise toluol pasi pechiito checatalyst.

Zvekuchengetedza

Cresol ine muchetura, uye kubata kwakananga kana kufemera pamusoro pehuwandu hwecresol kunogona kukanganisa hutano. Nzira dzekuchengetedza dzakakodzera dzinofanirwa kuteverwa kana dzichishandiswa, uye midziyo yekudzivirira yakakodzera inofanira kushandiswa.

Dzivisa kubata kwenguva refu neganda uye dzivisa kupinza mhute yaro.

Paunenge uchichengeta uye uchibata toluenol, inoda kuvharwa zvakanaka uye kuchengetwa kure nekupisa uye kupisa kwakanyanya.

Zvakapfuura: Phenol(CAS#108-95-2)

Zvinotevera: Ethyl maltol(CAS#4940-11-8)
