Synthetic cooking oils containing dicarboxylic acid esters

Abstract

Diesters of the formula ##STR1## wherein R 1 and R 2 are hydrogen or alkyl of from 1 to about 20 carbon atoms, and X and Y are alkyl, alkenyl or .[.dienyl.]. .Iadd.alkadienyl .Iaddend.of from about 12 to about 18 carbon atoms, useful as low calorie synthetic oils suitable for consumption by mammals.

What is claimed is: .[.1. A diester of the formula ##STR4## wherein R 1  and R 2 , which may be the same or different, are hydrogen or alkyl from 1 to 20 carbon atoms, with the proviso that at least one of the R groups, R 1  or R 2 , is an alkyl of from 1 to 20 carbon atoms; X is an alkyl, alkenyl or dienyl radical from 12 to 18 carbon atoms, and Y is an alkenyl or dienyl radical of from 12 to 18 
     
        carbon atoms..]. .[.2.  A diester as claimed in claim 1, wherein one of R 1  and R 2  is hydrogen and the other is an alkyl of 16 carbon atoms..]. .[.3. A diester as claimed in claim 1, wherein both R 1  and 
     
     
        R 2  are alkyl of 16 carbon atoms..]. 4. A diester .[.as claimed in claim 1,.]. .Iadd.of the formula ##STR5##.Iaddend. wherein R 1  and R 2 , which may be the same or different, are hydrogen or alkyl of from 1 to 20 carbon atoms, with the proviso that at least one of the R groups, R 1  or R 2 , is an alkyl of from 1 to 20 carbon atoms, wherein X and Y are both .[.alkenyl or dienyl radicals having from 12 to 18 carbon atoms.]. .Iadd.oleyl or linoleyl 
     
     
        radicals.Iaddend.. 5. The diester of claim 4 wherein one of the groups R 1  and R 2  is hydrogen and the other is an alkyl of 16 carbon atoms and both X and Y are .[.alkenyls of 18 carbon atoms.]. .Iadd.oleyl 
     
     
        radicals.Iaddend.. 6. A diester as claimed in claim .[.1.]..Iadd.4.Iaddend., wherein both R 1  and R 2  are alkyl of 16 carbon atoms and X and Y are both .[.alkenyl or dienyl radicals having from 12 to 18 carbon atoms.]..Iadd.oleyl or linoleyl radicals.Iaddend.. 
     
     
           The diester of claim 6 wherein X and Y are .[.alkenyls of 18 carbon 
     
     
        atoms.]..Iadd.oleyl radicals.Iaddend.. 8. The compound .[.hexadecyldioleylmalonate.]. .Iadd.dioleylhexadecylmalonate.Iaddend.. 
     
     
           The compound .[.dihexadecyl dioleylmalonate.]. .Iadd.dioleyl dihexadecylmalonate.Iaddend.. .[.10. A synthetic edible oil comprising one or more compounds of the formula ##STR6## wherein R 1  and R 2 , which may be the same or different, are hydrogen or alkyl of from 1 to 20 carbon atoms, X is an alkyl, alkenyl or dienyl radical of from 12 to 20 carbon atoms, and Y is an alkenyl or 
     
     
        dienyl radical from 12 to 20 carbon atoms..]. 11. A synthetic edible oil comprising a mixture of .[.hexadecyl dioleylmalonate.]. .Iadd.dioleylhexadecylmalonate .Iaddend.and .[.dihexadecyl dioleylmalonate.]. .Iadd.dioleyldihexadecylmalonate.Iaddend.. .Iadd.12. A synthetic edible oil comprising one or more compounds of the formula: ##STR7##.Iaddend. wherein R 1  and R 2 , which may be the same or different are hydrogen or alkyl of from 1 to 20 carbon atoms, and X and Y independently each are an alkenyl or alkadienyl radical having from 12 to 
     
     
        18 carbon atoms.  .Iadd.13.  A synthetic edible oil as claimed in claim 12, wherein one of R 1  and R 2  is a hydrogen and the other is an alkyl of 16 carbon atoms. .Iaddend. .Iadd.14. A synthetic edible oil as claimed in claim 12, wherein both R 1  and R 2  are alkyl of 16 carbon atoms. .Iaddend. .Iadd.15. A synthetic edible oil as claimed in claim 12, wherein both X and Y are oleyl or linoleyl radicals. .Iaddend.
