FIELD: chemistry.
SUBSTANCE: invention relates to ether oil production. The method involves grinding softwood, extraction with liquid carbon dioxide at 20-22°C and 6-7 MPa to obtain a carbon dioxide extract, its concentration at 70±5 °C for 8-10 minutes with removal of the extraction agent, stripping with jet steam for 20-25 minutes to obtain extraction ether oil containing 72-80% monoterpene hydrocarbons and 0.8-1.0% semi-volatile compounds.
EFFECT: invention enables to obtain ether oil from softwood similar to native oil, characterised by a pleasant smell and colour, and also endowed with bactericidal properties.
