Abstract
A variety of betaine esters, including dialkylaminoalkyl cocoate betaines and dialkylaminoalkyl hydrogenated cocoate betaines are disclosed. These betaines can be advantageously prepared in high yield and purity by a three-step transiterification chemoenzymatic process or a two-step direct esterficiation chemoenzymatic process. These betaine esters have excellent surfactant properties.
