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

Intshayelelo

I-2, uhlobo lwe-organic compound, i-chemical formula yi-C8H9NO2. Iphuma kwi-nicotinic acid kwaye ibonakala njengento eqinileyo yekristale engenambala.

Ikhompawundi inenqanaba eliphezulu lokunyibilika kunye nenqanaba lokubilisa kwindawo yobushushu begumbi. Iyanyibilika kwizinyibilikisi eziphilayo ezifana ne-alcohol, i-chloroform kunye ne-ether, ngelixa ukunyibilika kwayo emanzini kuphantsi.

I-2, i-asidi inoluhlu olubanzi lokusetyenziswa kwiinkalo zekhemikhali yamayeza kunye ne-organic synthesis. Ingasetyenziswa njenge-pharmaceutical intermediate okanye njenge-catalyst ye-organic synthesis. Ekubeni inokwenza ii-complexes ngee-ion zetsimbi, ingasetyenziselwa kwi-chemistry yokulungelelanisa.

Indlela yokulungiselela i-2, i-asidi idla ngokudityaniswa ukusuka kwizinto zokuqala ze-toluene ngokusebenzisa uchungechunge lwee-chemical reactions. Amanyathelo athile abandakanya i-methylation, i-carbonylation, i-chlorination kunye ne-acidification.

Ngokuphathelele ulwazi lwayo lokhuseleko, i-2, i-asidi kufuneka iphathwe ngokuqaphela ukuba iqinile okanye isisombululo. Inokubangela ukucaphuka eluswini, kwamehlo nakwindlela yokuphefumla, ngoko ke izixhobo zokuzikhusela kufuneka zinxitywe ngexesha lokusebenza. Ukongeza, ikwayinto enokutsha kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye nee-oxidants ezinamandla. Ukunyamekela kufuneka kuthathwe ukuphepha ukuphendula kunye nezinye iikhemikhali ngexesha lokugcinwa kunye nokusetyenziswa. Kwimeko yengozi, amanyathelo afanelekileyo angxamisekileyo kufuneka athathwe ngokukhawuleza kwaye uncedo lwengcali kufuneka lufunwe.
