Mawu Oyamba
Acid ndi organic pawiri ndi mankhwala chilinganizo C7H7NO2. Ndi mtundu wa crystalline wolimba, wosungunuka m'madzi ndi organic solvents.
Acid ali ndi ntchito zosiyanasiyana. Itha kugwiritsidwa ntchito ngati wapakatikati mu kaphatikizidwe ka organic pokonzekera mankhwala ena. Itha kukhalanso ngati ligand ya organometallic complexes ndikutenga nawo gawo pazothandizira. Kuphatikiza apo, itha kugwiritsidwanso ntchito popanga mankhwala enaake.
Pali njira zambiri zokonzekera ICT. Njira imodzi yodziwika ndi kaphatikizidwe ndi mankhwala ndi makutidwe ndi okosijeni wa toluene. Mwachindunji, toluene imayamba kuchitidwa ndi acetaldehyde pamaso pa oxidizing agent kuti ipange 3-methyl-4-picolinic acid ester, yomwe imayikidwa ndi acid hydrolysis kuti ipeze mankhwala omwe akutsata.
Chitetezo cha asidi ndichokwera, koma zinthu zina zachitetezo ziyenera kutsatiridwabe. Valani zida zodzitetezera zoyenera monga magalasi ndi magolovesi mukamagwira ntchito. Pewani kutulutsa fumbi ndi mpweya zomwe zimatuluka ndikupewa kukhudzana ndi khungu. Pakusungirako ndi kunyamula, chidwi chiyenera kuperekedwa ku njira zoteteza chinyezi, zosawotcha ndi kuphulika. Mukamwedwa mwangozi kapena kukhudzana, funsani upangiri wachipatala mwachangu ndikubweretsa zidziwitso zachitetezo cha mankhwalawa kuchipatala.
