Nhanganyaya
Tetramethylguanidine, inozivikanwawo seN,N-dimethylformamide, ikristaro isina ruvara yakasimba. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza tetramethylguanidine:
Hunhu:
- Tetramethylguanidine yakasimba alkaline uye inogona kuumba yakasimba alkaline mhinduro mune aqueous solution.
- Icho chigadziko chisina kusimba chakaenzana neanhydrous mhinduro, uye inogona kushandiswa seanogamuchira hydrogen ions.
-Iyo yakasimba pakudziya kwekamuri, asi inogona kukurumidza kunyungudika kuita gasi risina ruvara kana yapiswa.
- Ikomboni ine yakasimba hygroscopicity.
Shandisa:
-Tetramethylguanidine inonyanya kushandiswa sealkali catalyst mune organic synthesis reactions.
- Inogona zvakare kushandiswa mumaindasitiri akadai sedhayi yepakati, electroplating, inochinjika polyurethane furo, nezvimwe.
Nzira:
-Tetramethylguanidine inogona kugadzirirwa nekuita kweN,N-dimethylformamide ine ammonia gasi pakumanikidzwa kukuru.
- Iyi nzira inowanzoda kupisa uye inoitwa pasi pekuchengetedzwa kwegasi inert.
Zvekuchengetedza
- Tetramethylguanidine mushonga une muchetura uye unofanirwa kudzivirirwa pakubata neganda nemaziso. Pfeka magirovhosi ekudzivirira uye magirazi paunenge uchishandisa.
- Inogona kukonzera kutsamwa kwemaziso neganda, uye kukonzera kunetseka kufema uye zviratidzo zvechepfu.
- Kuchengetedza kunofanira kutorwa kudzivirira kusangana neoxidants, acids uye zvinhu zvinopisa panguva yekushandiswa nekuchengetedza.
- Pakubata tetramethylguanidine, nzira dzekushandisa murabhoritari dzakakodzera uye maprotocol ekubata zvakachengeteka anofanirwa kuteverwa.
