With the promising results in hand‚ we next examine the catalytic efficiency of complex 2 for a wide range of aromatic‚ heterocyclic‚ cyclic and aliphatic ketones. To compare the results‚ all the reactions were carried out under identical conditions. The alcoholic products were analysed by GC-MS and 1H-NMR (entries 2‚ 15 and 16) after doing the required workup (Figs

Experiment 3 Preparation of 2‚ 4-Dinitrodiphenylamine Courtney Elahee Claim: The evidence will show that the red solid collected after recrystallization from the nucleophilic aromatic substitution of 2‚ 4-dinitrobromobenzene and aniline has the characteristics of 2‚ 4-dinitrodiphenylamine. Evidence: The procedure was carried out as described by Ault1 and the lab manual2. 2‚4-dinitrobromobenzene (0.92g‚ 3.75mmol‚ pale yellow solid) and aniline (0.7mL‚ 0.7g‚ 7.5 mmol) were boiled in ethanol (10mL)

Abstract Perfumes are being produced not only through the use of essential oils; fixatives and solvents; plant‚ animal and synthetic sources but also through the use of the fragrant oils in the natural essences of flower blossoms. This research study aims to unveil ways on how to produce perfumes through the use of lilac and lavender extracts. Among of the processes involved in the manufacture of perfumes- Collection‚ Blending and Aging‚ these ways are the methods in the process of Collection:

The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

Polymers are everywhere in our life. Many industries extremely rely on polymers‚ for example‚ food court‚ tons o ’toys and dollar dungeon. Those all are stuff made out of polymers. In addition there are lots kind of polymers ‚ such as aramid‚ Carbon fiber‚ Rayon and so on. Now‚ this Essay will investigate Tons

hypothesis is that exposure to fumes‚ at higher environmental temperatures‚ will result in quicker death. Gasoline is obtained from petroleum in oil refineries‚ and used as fuel in combustion engines. It is made of over 250 types of hydrocarbons. Aromatic hydrocarbons like toluene and benzene are used to increase the octane rating of gasoline. Other additives are also added to improve engine performance and reduce the emission of harmful gasses formed as byproducts of the combustion process. Some

(Author’s name) (Professor’s name) (Course details) (Date Abstract The aim of the lab was to separate and analyse analgesic drugs in a drug tablet. The method used to separate the components was Thin Layer Chromatography (TLC) with silica adsorbent as the stationary phase and 0.5% glacial acetic as the mobile phase. In one plate‚ five known samples were used as the reference‚ that is: Aspirin; Caffeine; Ibuprofen; and Salicylamide. Aspirin and Salicylamide were the only samples that fluoresced
