Isingeniso

I-2,6-Diaminotoluene, eyaziwa nangokuthi i-2,6-diaminomethylbenzene, iyinhlanganisela yezinto eziphilayo.

 

Izakhiwo kanye nokusetshenziswa:

Iyingxenye ebalulekile ye-organic synthesis futhi ingasetshenziswa ukulungisa izinhlobo ezihlukahlukene ze-organic compounds. Isibonelo, ingasetshenziswa ekulungiseleleni udayi, izinto ze-polymer, izithasiselo zenjoloba, njll.

 

Indlela

Kunezindlela ezimbili eziyinhloko ezivame ukusetshenziswa. Enye itholakala ngokusabela kwe-benzoic acid nge-imine ngaphansi kwezimo ze-alkali, kanti enye itholakala ngokunciphisa i-hydrogenation ye-nitrotoluene. Lezi zindlela ngokuvamile zenziwa endaweni yaselabhorethri futhi zidinga izinyathelo zokuphepha ezifanele, njengokugqoka amagilavu ​​okuzivikela, izibuko, nezinto zokuphefumula.

 

Ulwazi Lokuphepha:

Kuyinhlanganisela yezinto eziphilayo ezingase zibe nemiphumela ecasulayo futhi elimazayo emzimbeni womuntu. Izinqubo zokusebenza zokuphepha ezifanele kufanele zilandelwe ngesikhathi sokusetshenziswa nokugcinwa ukuze kuqinisekiswe ukungena komoya okufanele kanye nezinyathelo zokuvikela.
