Claims
- 1. A process for preparing an ester of the formula: ##STR4## which comprises dehydrogenating and esterifying at least two moles of a primary 2-substituted alcohol of the formula: ##STR5## wherein R.sub.1 is straight chain or branched chain alkyl having 3 to 20 carbon atoms and R.sub.2 is a straight chain or branched chain alkyl having 2 to 18 carbon atoms, or a mixture of such alcohols at about 170.degree. C.-240.degree. C. in the presence of a two-component catalyst system consisting essentially of (a) at least about 0.0024 wt. % platinum in the form of a dispersion of 1-10 wt. % platinum on a high surface area activated carbon support and (b) at least about 0.2 wt. % NaOH, KOH or LiOH, said percentages of said catalyst components being based on the amount of alcohol in the reaction mixture.
- 2. The process of claim 1 wherein the second component of the catalyst is NaOH present in an amount of about 4 wt. % to about 10 wt. %.
- 3. The process of claim 1 wherein there is present 0.005 to 0.008 wt. % platinum.
- 4. The process of claims 1 or 3 wherein the platinum on activated carbon catalyst has a surface area of about 1000 to 1200 M.sup.2 /g. and a mean particle size of less than 100 microns.
- 5. The process of claim 1 wherein the temperature is 185.degree. C. to about 200.degree. C.
