Also, - are added to the catalyst. Thus, aldehyde is produced.

carbon monoxide and hydrogen gas

To obtain the oxo alcohol specifically the 2- ethylhexanol, it will undergo several processes such as-

hydroformylation, aldolisation, hydrogenation and finally, the refining.

For the hydrogenation process, there are two ways that can be used namely -

the liquid-phase and vapour-phase hydrogenation schemes

First method is made by the - wherein the propylene will be subjected to hydroformylation. Then, the resulting product which is the - is added with an aldol.

Hydroformylation

Question	Answer
is a process of producing aldehyde from an olefin or alkene. The said reaction together with other process like hydrogenation is used in the industrial setting to produce several products like alcohol, detergent and plasticizers.	Hydroformylation reaction
In hydroformylation, it uses a catalyst such as - for the reaction to occur	Rhodium and Cobalt
Also, - are added to the catalyst. Thus, aldehyde is produced.	carbon monoxide and hydrogen gas
Hydroformylation or also known as the Oxo-reaction is a process which produces aldehydes or alcohol from -.	α- olefins
In addition,- is known as the most active catalyst of hydroformylation	rhodium catalyst
First, the alkene undergoes a hydroformylation reaction thus forming an aldehyde. Then, the aldehyde is subjected to - and will result to alcohol.	hydrogenation process
According to -, a major manufacturer of oxo alcohols	LP Oxo Technology
To obtain the oxo alcohol specifically the 2- ethylhexanol, it will undergo several processes such as-	hydroformylation, aldolisation, hydrogenation and finally, the refining.
For the hydroformylation reaction, the feed used will be the - which will then be reacted with carbon monoxide and hydrogen to generate butyraldehyde.	propylene
A homogeneous rhodium based catalyst was also added to give a 10:1 isomer ratio of -.	n- butyraldehyde
Aldolisation is the next reaction wherein the n- butyraldehyde is converted into - by two steps.	2‐ ethylhexanol (2‐EH)
In addition, - is usually present for the aldolisation and dehydration reaction to occur.	caustic soda
For the hydrogenation process, there are two ways that can be used namely -	the liquid-phase and vapour-phase hydrogenation schemes
homogenous - is used in the hydroformylation of the alkene and as a catalyst it speeds up the reaction. Then, the catalyst used in the hydroformylation will be decomposed by the gases which contains oxygen	cobalt catalyst
Next, there will be a separation between the Co catalyst and the organic phase. After, the non-converted olefins will be isolated from the aldehyde with the use of the -	distillation operation
The conditions for this process to occur are at pressure of -and a temperature between-.	27 to 30mPa ; 150 to 170°C
First method is made by the - wherein the propylene will be subjected to hydroformylation. Then, the resulting product which is the - is added with an aldol.	Johnson Matthey Process Technologies; butyraldehyde
