The invention relates to a continuous method for producing esters, in which at least one polyol ester of formula (I) (R
1
—COO)
m
R
2
(I), where R
1
represents hydrogen or an optionally substituted hydrocarbon group containing 1 to 50 carbon atoms, R
2
represents an optionally substituted hydrocarbon group containing 2 to 10 carbon atoms, and m represents a number from 2 to 10 and is smaller than or equal to the number of carbon atoms in R
2
, is reacted with at least one monohydric alcohol of formula (II) R
3
—OH (II), where R
3
represents an optionally substituted hydrocarbon group containing 1 to 30 C atoms, using microwave radiation in a reaction tube, the longitudinal axis of which extends in the direction of propagation of the microwaves of a single-mode microwave applicator, so as to obtain at least one ester of formula (III) R
1
—COO—R
3
(III), where R
1
and R
3
have the meanings indicated above.
