The synthesis is usually conducted at 200300 C and 3510 MPaIn this temperature range the maximum theoretical once-through conversion which is limited by the reaction equilibrium is 5575 36Because of heat management the once-through conversion is. A column still can achieve a vapor alcohol content of 95 ABV.

Methanol is usually produced with high selectivity although minor amounts of side products are found.

. In this a series of cups or bowls were set upon a stepped support with a wick of cotton or felt-like material which had been wetted with water or a clear liquid with each step dripping down. A column still also called a continuous still patent still or Coffey still is a variety of still consisting of two columns. A spiral still is a type of column still with a simple slow air-cooled distillation apparatus commonly used for bootlegging.

Column and cooler consist of a 5-foot-long 15 m copper tube wound in. In early alchemy and chemistry otherwise known as natural philosophy a form of distillation by capillary filtration was known as a form of distillation at the time.
