Abstract
Det kreves en fremgangsmåte ved rensing av en inert gass-strøm fra en tranesterifikasjonsreaksjon hvori en lavere alkylalkohol frigis under reaksjonen. En annen anvendelse av prosessen er å lage lavere al- kyl- , f.eks. metyl, estere av fettsyrer gjennom en transesterifikasjonsreaksjon ved anvendelse av gassformige alkoholer som en kilde for de lavere alkylalkoholer. Alkoholen fortynnes med nitrogen eller annen inert gassbærer og reageres med fett- syreester, fortrinnsvis et triglyserid, for å danne den korresponderende metyl- eller lavere alkylfett- syreester.
