Abstract: Described is a process of making pseudoionone and hydroxy pseudoionone comprising the steps of (i) preparing a first aqueous mixture comprising first concentrations of acetone, citral and hydroxide, (ii) producing a second aqueous mixture by allowing to react for a reaction time the components of the first aqueous mixture and (iii) producing a third aqueous mixture by adding to the second aqueous mixture a second amount of hydroxide so that an additional amount of pseudoionone is formed in the third aqueous mixture. The invention further suggests an apparatus for making pseudoionone and hydroxy pseudoionone as well as to a respective process and use of said apparatus in making pseudoionone and hydroxy pseudoionone.

Abstract: A process for recovering isoprenol essentially free of formaldehyde from a stream of crude isoprenol containing isoprenol, water and formaldehyde, the process comprising subjecting the stream of crude isoprenol or an isoprenol containing fraction thereof to distillation in a low-boiler separation tower operated at a pressure of 2.5 bara or higher to obtain a distillate stream containing aqueous formaldehyde and a bottoms stream containing isoprenol. The process of the invention allows for obtaining isoprenol essentially free of formaldehyde. Further provided is a plant for recovering isoprenol essentially free of formaldehyde from a stream of crude isoprenol containing isoprenol, water and formaldehyde, the plant comprising a first low-boiler separation tower, a second low-boiler separation tower, and a finishing tower.

Abstract: The invention relates to an apparatus (1) for producing pseudoionone and hydroxy pseudoionone. It suggests an apparatus (1) comprising first and second substantially vertically oriented reactor chambers oriented such that components flow through the first and second reactor chambers in different directions, 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, 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, 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. The invention further suggests a method and a use for producing pseudoionone and hydroxy pseudoionone.
