Abstract A peaking process is disclosed for preparing aldehydes or carboxylic acids from a mixture of alpha olefins. The alpha olefins are separated into at least two fractions consisting of a low molecular weight fraction and a high molecular weight fraction. The high molecular weight fraction is isomerized and the two fractions oxidized. The low molecular weight fraction will oxidize to Cn 1 product and C1 product. The high molecular weight fraction will cleave at the double bond giving products containing the number of carbon atoms of the groups on either side of the double bond. The procedure has great versatility by varying the number of fractions and isomerizations. With alpha olefins prepared from metal alkyl growth product, M-values also have an influence on the final product.
The process of claim 1 wherein the alpha olefins are obtained by displacement of aluminum trialkyls.
Claim 2
Dependent Claim
20 words
The process of claim 2 wherein the alpha olefins contain even carbon atom olefins of two to 30 carbon atoms.
Claim 3
Dependent Claim
55 words
The process of claim 3 wherein the olefins are fractionated into at least three fractions and the lowest molecular weight fraction is recycled to the aluminum trialkyl zone for regrowing, a low molecular weight fraction but higher than the lowest molecular weight fraction is oxidized and a higher molecular weigh fraction is isomerized and oxidized.
Claim 4
Dependent Claim
16 words
The process of claim 4 wherein the lowest molecular weight fraction consists of ethylene and butene-1.
Claim 5
Dependent Claim
34 words
The process of claim 5 wherein the low molecular weight fraction to be oxidized consists of C6 to C12 alpha olefins and the higher molecular eight fraction consists of C14 to C30 alpha olefins.
