Isingeniso
I-5-(Trifluoromethyl) i-pyridine-2-carboxylic acid iyinhlanganisela ye-organic enefomula yamakhemikhali C7H3F3NO2.
Imvelo:
-Ukubukeka: Ayinambala ikristalu ephuzi noma impushana ekhanyayo.
-Indawo yokuncibilika: 126-128°C
-Indawo yokubilisa: 240-245°C
-Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether nama-ketone.
Sebenzisa:
I-5-(i-Trifluoromethyl) i-pyridine-2-carboxylic acid iyingxenye ebalulekile emkhakheni we-synthesis nemithi. Ingasetshenziselwa ukuhlanganisa izinhlanganisela ezihlukahlukene eziphilayo, njengezidakamizwa, odayi nezibulala-zinambuzane. Ingasetshenziswa futhi njengama-catalysts, ama-ligands nama-reagents.
Indlela Yokulungiselela:
I-5-(Trifluoromethyl) pyridine-2-carboxylic acid ngokuvamile ilungiswa ngokusabela ku-2-picolinic acid chloride nge-trifluoromethyl amine. Inqubo ethize yokulungiselela ingase ihlanganise izindlela zamakhemikhali zokwenziwa kwe-organic kanye nama-reagents, okudingeka ukuba wenziwe ngaphansi kwezimo zaselabhorethri.
Ulwazi Lokuphepha:
I-5-(Trifluoromethyl)pyridine-2-carboxylic acid ingeyamakhemikhali futhi inezingozi ezithile zokuphepha. Izinqubo ezifanele zaselabhorethri kanye nezinyathelo zokuzivikela kufanele zilandelwe ngesikhathi sokusetshenziswa nokuphathwa. Gwema ukuthinta isikhumba, amehlo kanye nomgudu wokuphefumula, futhi ugweme amalangabi avulekile namazinga okushisa aphezulu. Kufanele igcinwe endaweni eyomile, enomoya omuhle, kude nezinto ezivuthayo kanye nama-oxidants. Sicela uthintane nezinto zokuphepha ezifanele kanye nezingcweti ukuze uthole ulwazi oluningiliziwe lokuphepha.
