of the fruit of the orange tree‚ and tomato juice is the liquid that results from pressing the fruit of the tomato plant. Common methods for preservation and processing of fruit juices include canning‚pasteurization‚ concentrating[1]‚ freezing‚ evaporation and spray drying. A concentrate is a form of substance which has had the majority of its base component (in the case of a liquid: the solvent) removed. Typically this will be the removal of water from a solution or suspension such as the removal

Solid-liquid extraction and liquid-liquid extraction of caffeine from tea leaves Andrew Jensen Lab partners: Jamie Pawluk‚ Joe Luong 230105559 Chem 250 L2 Oct‚4‚2012 Introduction: Extraction is the experimental procedure of obtaining a desired compound with the use of a solvent from either a liquid or solid mixture. Solid-liquid extraction involves the removal of organic compounds from solid material. This method of extraction may be achieved through extraction of the organic compound

water were disposed. Extraction of Eugenol A mixture of 25 ml distillate and 10 ml CH2Cl2 was placed into a separatory funnel. This mixture was extracted and 15 ml of extract was collected. In the same separatory funnel 10 ml of CH2Cl2 was added‚ extracted and collected. Another third extraction with 10 ml of CH2Cl2 was performed and collected. These 3 extracts were combined to give the total crude product. Drying & Purification of

and then the clear water is poured into another container. Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance. The other type of vaporization is boiling‚ which‚ instead‚ occurs within the entire mass of the liquid and can also take place when the vapor phase is saturated‚ such as when steam is produced in a boiler. Evaporation that occurs directly from the solid phase‚ as commonly observed

g). Females are larger than males. The blue-gray to brown-gray coat is extremely soft and dense; the fur is about an inch (2.5 cm) long. The coat protects the chinchilla from the extremely cold weather of the high Andes and helps prevent water evaporation. Keen sight and acute hearing warn the chinchilla of predators.I chose this animal because its so cute and it doesn’t harm anyone or thing. Few Chinchillas remain in the wild‚ but chinchillas are common in captivity. A few chinchillas were brought

After the reaction was deemed completed‚ the product was isolated and purified by ether extraction‚ aqueous extraction and evaporation. To determine how sodium hypochlorite acts as an oxidizing agent‚ the starting diol and final product were characterized through IR spectrum. Characterization of the peaks can be used to identify what functional groups are present

University of Santo Tomas‚ Manila‚ Philippines Abstract In this experiment we performed parallel chemical test method to identify an unknown. The reflux setup was used to prevent evaporation in mixing the reactants in an inert solvent with its boiling point. Another highlight of this experiment is the liquid-liquid extraction wherein a solution containing a mixture of compounds is shaken with a second solvent that is immiscible with it. The percent yield calculated was 59.23%. The characteristics of

Which layer will be the aqueous layer when using dichloromethane (methylene chloride) as the solvent (i.e.‚ top or bottom)? Which layer will be the aqueous layer when using ether as the solvent? 2. When everything has been separated in Part D‚ which compounds will be in test tubes 1‚ 2‚ and 3?
