Abstract
Clean and environmentally friendly processes for preparing epoxide compounds in one-step and in two-step using safe and inexpensive starting materials are provided. The catalysts used in the reaction are low-cost and can be recycled and reused. Processes for using epoxide compounds and their industrial applications are also provided.
Claims26
A process for preparing an epoxide, comprising:
- heating a mixture of a plurality of alkenes and a fatty acid at about 25° C. to about 100° C.;
- wherein a plurality of alkenes having following formula (I):
- wherein R and R′ are H or alkyl chains having 8 to 20 carbon atoms,
- adding an aluminum oxide catalyst to the reaction mixture;
- injecting hydrogen peroxide solution over a period of about 1 hour to about 48 hours into the reaction mixture;
- decanting the water from the reaction mixture;
- and
- collecting the epoxide.
