摘要：This invention relates to a process for condensing aldehydes to alpha-hydroxyketones in a liquid system containing an aldehyde and an active condensationcatalyst formed by the abstraction of HX from a thiazolium salt in which X is the anion.The reaction is carried out in the absence of a base (other than the active catalyst) andthe anion X. The catalyst is rendered free of the undesirable base and the anion Xbecause these are the cause of premature deactivation of the catalyst.
