Solvent extraction
| Oil glossary |
- A refining process used to separate components (unsaturated hydrocarbons) from lube distillates in order to improve the oil’s oxidation stability, viscosity index, and response to additives. the oil and the solvent extraction media are mixed in an extraction tower, resulting in the formation of two phases: a heavy phase consisting of the undesirable unsaturates dissolved in the solvent. and a lighter phase consisting of a high quality oil with some solvent dissolved in it. the phases are separated and the solvent recovered from each by distillation.
- The most common method for extracting fragrance from natural materials, solvent extraction consists of submerging/macerating the raw material in a chemical solvent (such as hexane) and then vacuum-separating the now extracted fragrant material from the solvent. this produces a solid known as a concrete, which can then be dissolved and distilled again with alcohol to produce an absolute.
- A refinery process that utilizes oil and a polar solvent like phenol, n-methyl pyrolidone, furfural, etc., to selectively separate unsaturates from lubricant distillates, in order to improve properties such as oxidation stability, viscosity index and additive response.

Extract, английский
- This is everything in a wine besides water, sugar, alcohol, and acidity.
- An extract is a perfume that has 15-45% compound in an alcohol base.

- Извлекать; выделять
- An alcoholic solution of fragrance oil. the traditional concentration of the fragrance oil in an extract is between 15 and 50% of oil in the finished extract. the layman refers to the extract as “perfume.”
- To build a dac package file that contains the definitions of all the objects in an existing database, as well as instance objects that are associated with the database. extract
- To decompress, or pull out, files from a compressed form. when you extract a file, an uncompressed copy of the file is placed in the folder you specify. the original file remains in the compressed folder. compressed files frequently have a .zip file name extension.
- To remove or duplicate items from a larger group in a systematic manner.

Extraction, английский
- Extraction is the process of removing essential oils from plant material using solvents, which are then evaporated, leaving just the oil.
- 1. the removal of part of the body, especially a tooth 2. in obstetrics, delivery, usually a breech presentation, which needs medical assistance
- Извлечение
- Выделение (сигнала); извлечение; добывание; экстрагирование
- A process for obtaining natural oils by means of tanks and solvents and is used with certain flowers and plants where the heat of steam distillation might damage or destroy the odorous substances or in such cases where the yield of oils is rather small. in one process, the tank is stationary and the solvent flows over the flowers or other natural matter. the other involves the use of a revolving unit inside of which the flowers move through the solvent. after removal of the solvent, alcohol is agitated through the remaining mixture of waxes and oils and the former is removed by chilling and filtering. the alcohol and oil mixture is then brought to the boiling point, the alcohol filtered off, and the concentrate allowed to remain for recovery. the concrete, as previously defined, is the pure essence in solid form from which an absolute is derived.
- Removal of one substance from another, often accomplished by a solvent.

Distillation, английский
- Перегонка
- A water purification process in which water is converted to a vapor by boiling it, and then reconverted to purified water by cooling the vapor. disc tumbler lock 316 the process of distillation distribution box
- The action of distilling a liquid
- One of the oldest methods of separating oils from flowers and still widely used. it is a heat-dependent process for separation and purification of a liquid mixture based on differences in vapor pressure of components of the mixture. in each case, the flowers or other sources of oil are changed into a still and heat is applied to separate the oil. one type involves direct contact between the plant material and boiling water. in another type, the heat source is steam that is blown through the flowers. the process involves vaporization of the more volatile component(s) and then condensation of the vapor back to a liquid. the water and oil are collected and as they separate, the oil is removed from the top.
