2 6-Dimethylpyridine-4-carboxylic acid (CAS# 54221-93-1)

Isingeniso

2, uhlobo lwenhlanganisela yezinto eziphilayo, ifomula yamakhemikhali yi-C8H9NO2. Iphuma ku-nicotinic acid futhi ibonakala iqinile njengekristale engenambala.

I-compound inezinga eliphezulu lokuncibilika kanye nendawo yokubilisa ekamelweni lokushisa. Incibilika kuzincibilikisi zemvelo ezifana notshwala, i-chloroform ne-ether, kuyilapho ukunyibilika kwayo emanzini kuphansi.

2, i-asidi inezinhlobonhlobo zokusetshenziswa emikhakheni yamakhemikhali okwelapha kanye nokuhlanganiswa kwezinto eziphilayo. Ingasetshenziswa njengengxenye yemithi noma njenge-catalyst ye-organic synthesis. Njengoba ingakha ama-complexes ane-ion yensimbi, ingasetshenziswa futhi kumakhemikhali wokuxhumanisa.

Indlela yokulungiselela i-2, i-asidi ivame ukuhlanganiswa kusukela ezintweni zokuqala ze-toluene ngochungechunge lokusabela kwamakhemikhali. Izinyathelo eziqondile zifaka i-methylation, i-carbonylation, i-chlorination kanye ne-asidi.

Mayelana nokwaziswa kwayo kokuphepha, i-2, i-asidi kufanele iphathwe ngokuqapha kungakhathaliseki ukuthi iqinile noma isixazululo. Kungase kubangele ukucasuka esikhumbeni, amehlo kanye nendlela yokuphefumula, ngakho-ke izinto zokuzivikela kufanele zigqokwe ngesikhathi sokusebenza. Ngaphezu kwalokho, iphinde ibe yinto evuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye nama-oxidants aqinile. Ukunakekela kufanele kuthathwe ukuze kugwenywe ukusabela kwamanye amakhemikhali ngesikhathi sokugcinwa kanye nokusetshenziswa. Uma kwenzeka ingozi, izinyathelo ezifanele eziphuthumayo kufanele zithathwe ngokushesha futhi kufanele kufunwe nosizo lochwepheshe.
