The present invention is directed to polyamines represented by the following general structure: ##STR1## where R is an organic group, R' is H or CH.sub.3, and

Polyamines and their preparation

Dihydroxy and polyhydroxy compounds are obtained from polymerized fatty acids by a liquid phase reaction at a temperature at about 500.degree. F. to about 650.degree. F., pressures up to about 1000 psi in the presence of a catalytic amount of a hydrogenation catalyst, along with removal of water by-product during the reaction.

Dihydroxy or polyhydroxy compounds and process for producing same

Esters are obtained from organic carboxylic acids and/or lower molecular weight esters thereof by a liquid phase reaction at temperatures of about 200.degree. C. to about 350.degree. C., pressures of about 50 psi to about 1800 psi, whereby water and/or alcohol by-product is removed during the reaction of the acid and/or lower molecular weight ester to the ester to thereby obtain the desired ester.
