ABSTRACT:
The present invention provides a catalyst composition suitable for the production of high boiling esters comprising a source of stannous tin and an alkali metal aluminate. In one preferred embodiment the catalyst comprises about 92 parts sand, about 5 parts stannous oxalate, and about 3 parts of a sodium aluminate, by weight, dry basis. This catalyst is particularly useful in making phthalates, adipates, sebacates and azelates which esters are chiefly used plasticizers.
