Indlela:
I-2,4-Dimethyl-5-aldehyde-pyrrole-3-carboxylic acid ingalungiswa ngokusabela i-aniline ne-malonic acid dianhydride. Izinyathelo zokusabela eziqondile zimi kanje:
I-aniline ne-malonic acid dianhydride iyaxutshwa futhi isabela ezingeni lokushisa elifanele ukuze yenze inhlanganisela ye-amil.
Khona-ke, ngaphansi kwezimo ezifanele, ukusabela kwe-redox kwenziwa ukunciphisa i-sulfil compound ku-2,4-dimethyl-5-aldehyde-pyrrole-3-carboxylic acid.
Ulwazi Lokuphepha:
Ulwazi oluqondile lokuphepha lwe-2,4-dimethyl-5-aldehyde-pyrrole-3-carboxylic acid: Sicela ubheke ishidi ledatha yokuphepha yale nhlanganisela. Lapho usetshenziswa, kufanele ulandele izinqubo eziphephile zokusebenza zaselabhorethri, ugqoke izinto zokuzivikela, uqinisekise ukuthi indawo yokuhlola inomoya omuhle, futhi ugweme ukuthintana nesikhumba namehlo. Kufanele futhi igcinwe endaweni epholile, eyomile, kude nomlilo nezinto ezivuthayo. Uma kuvuza, kufanele kuthathwe izinyathelo ezifanele ukubhekana nakho. Ukuze uqinisekise ukuphepha, funa isiqondiso sochwepheshe.
