FIELD: industrial organic synthesis. ^ SUBSTANCE: invention relates to industrial production of esters using recirculation circuit. Invention proposes introducing component into fluid reaction medium and/or fluid process medium comprising stages: (a) providing recirculation circuit including incoming stream and outgoing stream, wherein incoming stream is in fluid communication with fluid reaction mixture; (b) recirculation of at least part of reaction medium from stage (a) through recirculation circuit, wherein fluid reaction mixture flowing through recirculation circuit represents recirculation fluid medium; (c) depressing recirculation fluid medium from stage (b) with the aid of at least one depression device in at least one recirculation circuit point; and (d) supplying component into recirculation circuit in the vicinity of location of device serving to reduce pressure from stage (c) of in its location place in order to thereby introduce component into fluid reaction medium. ^ EFFECT: simplified process and increased economical efficiency thereof. ^ 25 cl, 4 dwg |
