< Topic > Solutions This invention being the manner which selects volatile odor chemical compound from the organicity raw materials which contain odor chemical compound, regards the manner which includes the following process: a) the aforementioned organicity raw materials, at least at temperature of the 10 - the 70, are made to contact with the carbonic acid dimethyl which is used with aforementioned bath as the composition during one bathing, the volatile odor chemical compound of the aforementioned organicity material is loaded in the aforementioned carbonic acid dimethyl composition, the process which liquid organicity phase is obtained b) the process which recovers aforementioned liquid organicity phase from aforementioned bath c) the liquid organicity phase which is recovered, when the carbonic acid dimethyl non- miscibile water phase which it occurs from the organicity material is included, decantation doing liquid organicity phase, the process which separates the carbonic acid dimethyl which loads volatile odor chemical compound from aforementioned non- miscibile water phase, removes water phase The process which removes carbonic acid dimethyl partly d) with evaporation, recovers the preliminary concentrated extract of volatile odor chemical compound After removing carbonic acid dimethyl partly e) with evaporation, when the preliminary concentrated extract of volatile odor chemical compound contains the water, decantation doing the preliminary concentrated extract, the process which removes the water The process which and f) concentrates the preliminary concentrated extract of volatile odor chemical compound with evaporation, obtains the extract of volatile odor chemical compound. This invention, the extract and the perfume and the perfume manufacturing industry component of the volatile odor chemical compound which is prepared by the manner of this invention, the food flavor or furthermore regards also the use to the cosmetics constituent. < Choice figure >
