The present invention concerns an isothermal reactor (1) comprising a substantially cylindrical shell (2), at least one catalytic bed (10) supported in the shell (2) and at least one heat exchange unit (13) supported in the bed (10), the heat exchange unit (13) comprising a plurality of exchangers (14) substantially box shaped, of essentially elongated rectangular and flattened structure, each of the exchangers (14) having opposite long sides (14a) parallel to the cylindrical shell (2) axis and opposite short sides (14b, 14c) extended perpendicularly with respect to the shell axis and comprising furthermore an inner chamber (18) through which a heat exchange operating fluid in intended to flow, wherein at least one exchanger (14) of such at least one heat exchange unit (13) is internally equipped with a plurality of separation baffles (19) extended from a short side (14b or 14c) of the exchanger to the opposite short side (14c or 14b) and in a predetermined spaced relationship with respect to the latter, defining in the inner chamber (18) a substantially zigzag fluid path having alternating ascending and descending portions.
