Nhanganyaya
Guaiacol is organic compound. Iyi inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza guaiacol luff:
Hunhu:
- Chitarisiko: Guaiac imvura inoonekera ine kunhuhwirira kwakakosha.
- Solubility: Inonyungudika mune zvakawanda organic zvinonyungudutsa, senge ethanol uye ether.
Shandisa:
- Mishonga yezvipembenene: Guaiacol dzimwe nguva inoshandiswa sechinhu chinoshandiswa mumishonga yezvipembenene.
Nzira:
Guaiacol inogona kutorwa kubva muhuni yeguaiac (chirimwa) kana kugadzirwa nemethylation ye cresol uye catechol. Synthesis nzira dzinosanganisira kuita kwep-cresol ine chloromethane yakagadziriswa nealkali kana p-cresol uye formic acid pasi peasidhi catalysis zvichingodaro.
Zvekuchengetedza
- Guaiacol vapor inotsamwisa uye inogona kuve nemhedzisiro inoshatirisa pameso, ganda, uye kufema system. Pfeka maziso ekudzivirira, magurovhosi uye mask kana zvichidikanwa.
- Inofanirwa kuchengetedzwa kure nemoto uye kupisa kwakanyanya, uye kuchengetwa mumudziyo usina mhepo kudzivirira kusangana neoxidants.
- Paunenge uchishandisa guaiacol munzvimbo ine mhepo inofefetera zvakanaka uye dzivirira kufemesa mhute yayo kwenguva yakareba.
- Bata mukomboni nemazvo zvinoenderana nematanho ekushanda akakodzera uye mirairo yekuchengetedza. Muchiitiko chekubata neganda kana kushandiswa, simbura pakarepo nemvura yakawanda uye tsvaga rubatsiro rwechiremba.
