Production of wood extracts via superheated liquids consists of application of ultra pure water and ethanol via an oven, with static and dynamic extraction

摘要

The production of wood extracts via superheated liquids comprises application of ultra-pure water and ethanol (100:0 to 40:60 by volume) at 80-300 degrees C for 10-120 minutes. Also claimed is apparatus implementing the process. An independent claim is also included for the apparatus which has a high-pressure pump (1), an adjustable-temperature oven (2) and an extraction chamber (3). A closing valve (4) and a selector valve (5) supplement a restrictor (6) for static and dynamic operation.
