Manufacture of neopentyl glycol (IV) |
摘要 |
<p>Neopentyl glycol is made from isobutyraldehyde and formaldehyde. The formaldehyde may be in the form of paraformaldehyde or aqueous formaldehyde. The aldol reaction product is mixed with a lower alcohol prior to hydrogenation to promote hydrogenolysis and allow recovery of high purity product by simple distillation. In a less preferred mode, the alcohol may be added after hydrogenation, resulting in a smaller improvement over previous processes.</p> |
