EC number: 271-363-2 | CAS number: 68551-11-1 A complex combination of products produced by the distillation of products from the hydrogenation of butanal from the hydroformylation of propene. It consists predominantly of organic compounds such as aldehydes, alcohols, esters, ethers and carboxylic acids having carbon numbers in the range of C4-C32 and boiling in the range of approximately 143°C to 282°C (289°F to 540°F).
