PROCESS FOR PRODUCING BENZYL ALCOHOLS

Title:

PROCESS FOR PRODUCING BENZYL ALCOHOLS

Document Type and Number:

Japanese Patent JP2011121929

Kind Code:

A

Abstract:

To provide a process which reduces the amount of unreacted benzaldehydes remaining and impurities formed and can industrially advantageously produce high-purity benzyl alcohols than in the past in a high yield.

By dropping both a benzaldehyde (B) and 1-5 moles formaldehyde (A) per mole benzaldehyde in a solvent (D) in the presence of a base (C), the amount of unreacted benzaldehyde remaining and impurities formed is reduced to industrially more advantageously obtain a high-purity benzyl alcohol in a better yield than in the past.
