Red Copper Pot Still Distillation
Copper-The Best Material For Distiller
Besides the physical features of thermal conductivity and malleability, there are three chemical features of copper make it important to distillation.
Copper catalyzes esterification reactions
Copper is an active chemical
Copper can act as a filtering medium
Copper is the catalyst for esterification reactions
In the case of esterification reactions, esters are produced. which contribute to pleasant floral and fruity aromas. For example, the acetic acid and ethanol react in a copper-catalyzed reaction to produce ethyl acetate, which has fruity and floral aromas. Butyric acid and alcohol, with the catalysis of copper, result in ethyl butyrate, a compound with a pineapple-like aroma.
Copper plays the role of a reactive chemical
It reacts with sulfides, which has unpleasant and stink odor, and forms copper sulfate. It effectively eliminates toxic hydrocyanic acid by combining with it to form copper soap.
Copper can act as a filtration medium
Copper can attracting and binding certain compounds, onto its surface. It can adsorb compounds like aldehydes, which contribute to harsh or pungent flavors, resulting in a more refined and mellow spirit.
