The liquid-phase epoxidation reaction of an olefin with hydrogen and oxygen in the presence of a catalyst mixture containing a titanium zeolite and a supported catalyst surprisingly produces less ring-opened products such as glycols when performed in the presence of a buffer. This is particularly surprising because a typical palladium on titanium zeolite catalyst is little effected by the presence of a buffer. Surprisingly, the use of a buffer also typically improves the activity of the process.

On a mis en évidence qu'en présence d'un tampon, la réaction d'époxydation de la phase liquide d'une oléfine avec l'hydrogène et l'oxygène en présence d'un mélange catalytique contenant une zéolite au titane et un catalyseur supporté donne, ce qui est remarquable, moins de produits à cycles ouverts tels que les glycols. Cela est d'autant plus remarquable que les catalyseurs standards de type palladium sur zéolite au titane sont peu affectés par la présence d'un tampon. Ce qui est remarquable, c'est que l'utilisation d'un tampon améliore également de façon caractéristique l'activité du processus.
