Abstract

POSTUPAK ZA PREČIŠĆAVANJE KARBOKSILNIH KISELINA. Karboksilne kiseline koje su proizvedene karbonilovanjem i koje imaju jodidne i oksidujuće nečistoće prečišćavaju se kontaktiranjem sa vodonik-peroksidom i regenerisanjem prečišćene kiseline destilacijom ili isparavanjem. Poželjno se kao katalizator koristi neka takva jaka kiselina kao što je sumporna kiselina. Kontaminacija proizvoda sa sumporom iz sumporne kiseline i sa viškom vodonik-peroksida može se smanjiti korišćenjem metalnih soli u fazi regenerisanja.
