Apparatus for and process of making pseudoionone and hydroxy pseudoionone

An apparatus (1) for producing pseudoionone and hydroxy pseudoionone, comprising

• a first vertically oriented reactor chamber (13) arranged such that components flow through the first reactor chamber in a first flow direction,
• a second vertically oriented reactor chamber (23) in fluid communication with the first reactor chamber (13), and the second reactor chamber (23) being oriented such that components flow through the second reactor chamber (23) in a second flow direction different from the first flow direction,
• wherein
• the first reactor chamber (13) is configured to receive a first component feed (C1) containing a first aqueous mixture through an inlet (15), and to produce a second aqueous mixture by allowing to react for a reaction time the components of the first aqueous mixture and wherein
• the apparatus (1) comprises a mixing device (17) positioned downstream of the first component feed inlet (15) and configured to add a second component feed (C2) to the first component feed (C1) when the second aqueous mixture has formed thereof, and
• the second reactor chamber (23) is configured to receive the first and second component feeds unified in the mixing device (17) from the first reactor chamber (13) and to produce a third aqueous mixture from the first and second aqueous mixtures.
