Abstract: A process to produce a mono vinylether of formula (I) R-O-CH=CH 2 wherein R represents an organic group with at least three carbon atoms comprising a) reacting a mono hydroxy compound of formula (II) R-OH wherein R has the above meaning with acetylene in presence of a catalyst to get a product mixture comprising the mono vinyl ether, unconverted mono hydroxy compound and the catalyst b) adding an ester comprising at least one ester group of formula (III) X-O 2 C- wherein X is a hydrocarbon group comprising less carbon atoms than R to the product mixture obtained in process step a) and reacting the remaining mono hydroxy compound R-OH with the ester in the presence of the catalyst to get a transesterification product comprising at least one ester group of formula (IV) R-O 2 C- and an alcohol of formula (V) X-OH wherein R and X have the above meaning and c) isolating the mono vinyl ether from the product mixture obtained after process step b), optionally followed by purification of the mono vinyl ether by distillation.
