was added to the round bottom flask drop-wise with additional washing of ~2.0 mL of diethyl ether. Iodine (catalyst) was added to facilitate the reaction. Phenylmagnesium bromide was obtained upon cooling of the solution to room temperature. Benzophenone (1.09 g) and diethyl ether (2.0 mL) mixture was then reacted with the Grignard product for 15 minutes. Red solidified adduct was observed. Next HCl (6.0 mL) was added drop-wise to the adduct; bilayer of triphenylmethanol and inorganic impurities

Extraction and analysis of two compounds from unknown solution C ABSTRACT Liquid C and solid C were both extracted from unknown solution by first using chemically active liquid-liquid extract‚ followed by vacuum filtration. Liquid C and solid C were then purified with the use of simple distillation and recrystallization respectively. Through the process of recrystallization‚ the percentage purity of solid C was found to be 6.01%. The melting point range of purified solid C was 117.0 – 119

brown and cloudy. The conical vial was then rinsed with 2 ml of anhydrous ether to get any remaining solution into the reaction vessel. Simultaneously‚ 1.09 g of benzophenone and 2ml of anhydrous ether were added to a 3ml conical vial and gently stirred. The reaction vessel was taken off of the hot plate and allowed to cool. The benzophenone was then added to the reaction mixture while stirring vigorously. The conical vial was washed with anhydrous ether and transferred to the mixture. The reaction

Lab II March 19‚ 2012 Abstract The purpose of this experiment was to synthesize the Grignard reagent‚ phenyl magnesium bromide‚ and then use the manufactured Grignard reagent to synthesize the alcohol‚ triphenylmethanol‚ by reacting with benzophenone and protonation by H3O+. The triphenylmethanol was purified by recrystallization. The melting point‚ Infrared Spectroscopy‚ 13C NMR‚ and 1H NMR were used to characterize and confirm the recrystallized substance was triphenylmethanol. Introduction

The Grignard Reaction Abstract Through the use of the Grignard reaction‚ a carbon-carbon bond was formed‚ thereby resulting in the formation of triphenylmethanol from phenyl magnesium bromide and benzophenone. A recrystallization was performed to purify the Grignard product by dissolving the product in methanol. From here‚ a melting point range of 147.0 °C to 150.8 °C was obtained. The purified product yielded an IR spectrum with major peaks of 3471.82 cm-1‚ 3060.90 cm-1‚ 1597.38 cm-1‚ and 1489

The identity of unknown liquid D was 2‚6 dimethyl pyridine‚ and the identity of unknown solid D was benzophenone. Introduction Chemically active extraction can be used to separate compounds of similar polarities by changing the polarity of one of the compounds in a mixture in order to extract and identify them. The polarities of molecules play an important

CHAPTER II RELATED LITERATURE Blumea balsamifera(sambong) A Phytochemical and Pharmacological Review Sambong (Blumea balsamifera) is a native flowering or weed that is endemic in the Philippines and other tropical countries. It is a popular herb especially for its healing properties including antidiarrhetic‚ antigastralgic‚ expectorant‚ stomachic‚ and antispasmodic‚ among others. Aside from these‚ sambong is also popular for being emmenagogues‚ or for stimulating menstruation or the blood flow

The mixture turned back to a brown color with the addition of the remaining bromobenzene and ether added at a dropwise rate. The reaction vessel became warm at this point. The mixture then turned a reddish‚ pink color with the addition of 9.1g benzophenone in 100mL anhydrous ethyl ether. During the reflux the reaction mixture first turned a “pepto bismal” pink color then became a thick white liquid/solid. When the sulfuric acid was added the solution turned a yellow
