A process for selectively preparing dihydroxyethyl piperazine by reacting hydroxyethyloxazolidinone with an acid catalyst wherein the selectivity of hydroxyethyloxazolidinone to dihydroxyethyl piperazine is at least 55%.

Preparation of dihydroxyethyl piperazine

A process of contacting an alkylene oxide with 2-methoxy-1-propanol (PM1) in the presence of an oligomeric Schiff base metal complex catalyst is disclosed. Further, a process involving contacting an alkylene oxide with an alkyl alcohol using an oligomeric Schiff base metal complex as a catalyst is also disclosed. Additionally, novel compositions which can be used as catalysts in processes involving the contacting of an alkyl alcohol with an alkylene oxide are also disclosed.

Alkoxylation processes and catalysts therefor

A process comprising contacting a polyhydric phenol or a polyaliphatic alcohol with an epihalohydrin in the presence of a catalyst comprising a Schiff base metal complex is disclosed.
