Abstract: Propylene is an important industrial intermediate for the production of propylene oxide and polypropylene, while isobutylene is similarly widely used for the production of a variety of industrially important products, such as butyl rubber. Both of propylene and isobutylene are obtained through the catalytic or steam cracking of fossil feedstocks, and the development of a commercially viable process for the direct conversion of alcohol to either material would accordingly be of great interest as fossil resources are depleted and/or become more costly to use, especially in consideration of increased demand for both of propylene and isobutylene. The present invention relates to the process for preparing lower olefins from primary alcohols. More particularly the present invention relates to the process of conversion of primary alcohols to lower olefins wherein the primary alcohols are obtained from renewable sources.

Abstract: A process for making a substantially nitrosamine-free, substantially peroxide-free, substantially colorless amine oxide solution comprises reacting a tertiary amine capable of forming an amine oxide with a less than stoichiometric amount of aqueous hydrogen peroxide in an aqueous medium while imposing on the aqueous medium a vapor space having a carbon dioxide partial pressure p(CO2) of less than 0.75 bar absolute. The process allows for obtaining amine oxides which are substantially nitrosamine-free, substantially peroxide-free, and substantially colorless. This unique combination of desirable features has not been achieved so far in a process only comprising oxidation and distillation.
