Abstract

Przedmiotem wynalazku jest sposób otrzymywania estrów kwasu mlekowego i mleczanomlekowego w reakcji alkoholizy poliestru alifatycznego. Rozwiązanie dotyczy w szczególności metody otrzymywania mleczanu etylu z jednoczesnym wytworzeniem mleczanomleczanu. Opracowana technologia wykorzystywana będzie w procesie syntezy mleczanu etylu oraz innych estrów kwasu mlekowego w wielu sektorach przemysłu.
