CHM1002 Synthesis of Benzanilide and Methyl 3-Nitrobenzoate and the Identification of ‘Unknowns’ from Spectroscopic and Physical Properties James Lucas 10394308 23/11/12 Introduction In this series of practicals it was the aim to synthesise both Benzanilide and Methyl 3-Nitrobenzoate. Benzanilide was synthesised using The Schotten Baumann reaction which takes a hydrogen atom from an amino group and substitutes it for an acyl group. For Methyl 3-Nitrobenzoate

using the resulting aldehyde‚ along with 2‚4-dimethylpyrole‚ a BODIPY dye was obtained [36]. To facilitate intersystem crossing‚ the 2- and 6- positions of the boradiazaindacene ring system were iodinated with an iodic acid-iodine mixture [37]. Bromination at the same positions was performed via N-bromosuccinamide (NBS) [38]. 8-Palmitoyl-1‚ 3‚ 5‚ 7-tetramethyl-2‚ 6 diiodo-4-bora‚ 3a‚ 4a-diaza-s-indacene was obtained by the iodination of 8-palmitoyl-1‚ 3‚ 5‚

Next‚ Cyclohexane and Toluene were distilled. The boiling points of cyclohexane and toluene had a difference of 35°C. Cyclohexane had a percent recovery of 10%. Toluene had a percent recovery of 17%.

and observed two peaks in my results. Therefore I concluded that cyclohexane was the low boiling point liquid. However‚ for the second liquid I guessed heptane first‚ and my results showed three peaks. Knowing that I had guessed wrong‚ I tested toluene mixed with my fraction C and only got two peaks. The high boiling point liquid proved to be

! Isolation of the Components of BC Powder Introduction Aspirin‚ Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this‚ the three components were forced into conjugate acid (or base) forms‚ causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel

Global toluene prices also rose on the back of high benzene prices and continued strength in the xylene markets.” The 7% increase in benzene‚ a petrochemical used in packaging‚ various plastics‚ nylon and other textiles‚ was the largest of the seven components that make up the PGPI. The December average price of benzene was $1‚495/mt‚ up from a November average of $1‚398/mt. Toluene‚
