Inventor(s) include Backes, Adrian; and Williams, Michael.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "The present invention provides a method for the production of a C2n unsaturated aldehyde, wherein n is in the range of and including 3 to 6, the method comprising: (iv) passing a crude aldol stream from an aldolisation reaction to a crude aldol distillation column operated under distillation conditions to form a bottom stream having an increased concentration of the C2n unsaturated aldehyde, water and heavies as compared to the crude aldol stream, and an overhead stream comprising unreacted Cn aldehyde, Cn-1 alkane(s), Cn-1 alkene(s) and a reduced concentration of the C2n unsaturated aldehyde, water and heavies as compared to the crude aldol stream; (v) passing the overhead stream from the crude aldol distillation column to a first condenser zone, the first condenser zone being configured to provide a first condensed stream comprising an increased concentration of unreacted Cn aldehyde and water as compared to the overhead stream from the crude aldol distillation column and an overhead stream comprising Cn- 1 alkane(s), Cn-1 alkene(s) and a reduced concentration of unreacted Cn aldehyde and water as compared to the overhead stream from the crude aldol distillation column; (vi) passing the overhead stream from the first condenser zone to a second condenser zone, the second condenser zone being configured to condense at least a portion of the overhead stream from the first condenser zone to provide Cn/Cn-1 condensate; and wherein at least a portion of the Cn/Cn-1 condensate is recovered and returned to upstream of the crude aldehyde distillation column or to the crude aldehyde distillation column."
