A method for preparation of an olefin from an alcohol

Abstract

The presently claimed invention is directed to a method for preparing at least one olefin of formula (I), wherein, R1, R2, R3 and R4 are independently selected from hydrogen, C1-C20 alkyl, substituted C1-C20 alkyl, C2-C20 alkenyl, substituted C2-C20 alkenyl, C2-C20 alkynyl, substituted C2-C20 alkynyl, C6-C20 aryl, substituted C6-C20 aryl, C5-C20 cycloalkyl, substituted C5-C20 cycloalkyl, C7-C20 arylalkyl, or substituted C7-C20 arylalkyl; or R1 and R2, together with the carbon to which they are attached, form a C5-C15 cycle, the method comprising: a step of contacting at least one alcohol of formula (II), wherein, R1, R2, R3 and R4 are as defined above; with at least one catalyst comprising at least one catalytically active metal selected from Platinum (Pt), Palladium (Pd), Nickel (Ni), Chromium (Cr), Molybdenum (Mo), Ruthenium (Ru), or combinations thereof, at a partial pressure in the range of 0.02 to 4 bar, and at a temperature in the range of 200° C. to 450° C.
