An extensive study applying 4 parameters was carried out: Time 5, 10,15,20,30 and 60 minutes , Stirring rate , , and r. The best Condition was found to be 30 min — r. Diluents were used such as benzene, kerosene and xylene. Rania Farouq , Yehia Selim. Published June 16,

Embed Size px x x x x The partition of a solute between two immiscible solvents is a major tech-nique in separation, both in the laboratory and in industry. This technique hasbeen designated liquidliquid distribution by the International Union of Pureand Applied Chemistry IUPAC , but it is more commonly called solventextraction, the term we use. Solvent extraction has been developed in a broadfieldof applications: 1 for studying inorganic andorganic complex equilibria,either for fundamental understanding of solution equilibria and kinetics orfor developing selective separation schemes; 2 for separations in analyticalchemistry; 3 for large-scale industrial separation processes in the inorganic,organic, pharmaceutical, and biochemical industries; and 4 for industrialwaste treatment. It also serves as a base for other analytical techniques, suchas liquid partition chromatography and ion-selective electrodes. The many uses of solvent extraction make the subject important foruniversity students of chemistry and chemical technology. Some universitiesoffer special courses in solvent extraction, whereas others include it as aminor topic in more comprehensive courses.

We present a systematic approach for predicting the best solvents for selective extraction of components with unknown structure from complex mixtures e. Its key advantage is that identification of the component s is unnecessary—prediction is based on a small set of experimental distribution coefficients obtained using a combination of shake-flask extraction and chromatographic analysis rather than structure-based descriptors. The methodology is suitable for the very common situations in practice where the desired compound needs to be separated from unknown impurities i. The proof-of-concept methodology was developed and evaluated using an extensive set of experimental distribution data of lignin-related compounds obtained in this work. Liquid—liquid extraction is a separation method widely used both on laboratory scale and in industrial processes due to its simplicity, low cost, suitability for thermally labile and high-boiling compounds, and easy scalability. However, systematic improvement of the process by predicting the effects of various parameter modifications is a challenging task.

4 Solvent Extraction Equilibria

И вот эти два интеллектуала, казалось бы, неспособные на вспышки иррациональной влюбленности, обсуждая проблемы лингвистической морфологии и числовые генераторы, внезапно почувствовали себя подростками, и все вокруг окрасилось в радужные тона. Сьюзан ни слова не сказала об истинной причине своей беседы с Дэвидом Беккером - о том, что она собиралась предложить ему место в Отделе азиатской криптографии.

На лицах тех застыло недоумение. - Давайте же, ребята. -сказал Джабба.  - Вы же учились в колледжах. Ну, кто-нибудь.

 - У него был врожденный порок сердца. - Никогда об этом не слышала. - Так записано в его медицинской карточке. Он не очень-то об этом распространялся. Сьюзан трудно было поверить в такое удачное совпадение.
