TransesterificationAbout Banner


The process in which an ester (typically a lower boiling ester), is converted into a higher boiling ester.
The high temperatures coupled with the fractional distillation makes this an ideal fit for Chemoxy, and we currently run processes for some of our customers using this chemistry.

The fractionation capabilities mean that we can separate and recover, or otherwise using valorisation of the alcohol that is being removed, thereby increasing cost effectiveness.

Chemoxy’s skill set, allows the products to be produced in high purity with low water content, often required as part of the anhydride specification, whether used in pharma, agrochemicals, F&F, electronics or other performance applications.

Products are isolated by intensive distillation fractionation, and thus there are benefits in the ability for us to achieve high purity and low water content, and to recycle acids and alcohols. Separation of products with boiling point differences of 5-10°C is achieved on our columns.

Our preference is for liquids, or products that melt below 50°C.
