Metil propionatoa edo metil propanoatoa konposatu organikoa da CH3CH2COOCH3 formula duena, esterren familiakoa. Hain zuzen ere azido propionikoaren metil esterra da. Likido kolorgea da erronaren antzeko fruta-usaina duena.
Sintesia
Metil propionatoa presta daiteke azido propionikoa metanolez esterifikatzen. Industrian etilenoa, karbono monoxidoa eta metanola erreakzionaraziz katalizatzaile baten laguntzaz prestatzen da. Katalizatzailea normalean nikel eta paladio konplexu bat izaten da[1].
C2H4 + CO + MeOH → MeO2CCH2CH3
Erabilera
Metil metakrilatoa sintetizatzeko usa daiteke. Lehenik formaldehidoz erreakzionarazten da eta, segidan, deshidratatzen da.
- MeO2CCH2CH3 + CH2O → MeO2CCH(CH2OH)CH3
- MeO2CCH(CH2OH)CH3 → MeO2CC(=CH2)CH3
Metil propionatoa disolbatzaile gisa baliatzen da laka eta nitrozelulosen kasuan.
Fruta-usaina duenez aromatizatzaile gisa ere erabiltzen da[2].
