Abstract

Forbedret fremgangsmåte ved fremstilling av høyrent, halogenfritt o-ftalaldehyd, ved hvilken a) tetrahalo-o-xylen ved en temperatur på 155-160oC og e t trykk på 2 til 5 bar, eventuelt i nærvær av en faseoverføringskatalysator, hydrolyseres til o-ftalaldehyd, som b) i en sur, alkoholisk oppløsning ved en temperatur på 0 til tilbakeløpstemperatur overføres til det korresponderende dialkoksyftalanet og derpå c) skjer en acetalspaltning ved sur hydrolyse ved en pH >1,5 til pH 7, hvorved det oppnås et høyrent halogenfritt o-ftalaldehyd.
