-kunyungudika nzvimbo: 168-170 ℃
-Solubility: Inonyungudika zvishoma mumvura, iri nyore kunyungudika mune organic solvents senge ethanol uye acetone.
-asidhi uye alkaline: isina simba asidhi
Shandisa:
-inonyanya kushandiswa mune organic synthesis seyakakosha reagent uye yepakati.
-Inogona kushandiswa kugadzira makemikari akadai semishonga, dhayi uye polymer zvinhu.
Kugadzirira nzira:
Inogona kugadzirwa nematanho anotevera: br> 1. Kutanga, pasi pemamiriro ekuita akakodzera, methyl bromide uye p-nitrobenzene sulfonamide inobatwa kuita methyl ester.
2. Zvadaro, iyo methyl ester inobatwa neine alkaline solution kuti iwane munyu.
Zvekuchengetedza
-inofanirwa kuchengetwa munzvimbo yakaoma, ine mhepo yakanaka, uye kudzivirira zuva rakananga.
-Panguva yekushanda, dzivisa kusangana neganda nemaziso. Kana zvaonekwa, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa.
-Pfeka midziyo yekuzvidzivirira yakafanira senge magirovhosi, magirazi ekudzivirira uye zvipfeko zvekudzivirira paunenge uchibata komboni.
-Usasanganise iyi komputa ine yakasimba oxidants uye yakasimba acids, nekuti inogona kukonzera njodzi.
-Usati washandisa kana kubata musanganiswa, mirairo yehutano yekuchengeteka inopiwa nemutengesi inofanira kuverengwa zvakanyatsonaka.
