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

acidiphilum‚ sulfolobus solfataricus. Factor causing low permeability of acidophile membranes. Monolayer composed of unique “tetraether lipids” in which two hydrophilic heads attached to the same hydrophobic tail through ether bonds – more stable‚ less fluid Bulky isoprenoid core. Ether linkage characteristic of these membranes less sensative to acid hydrolysis than ester linkage. 2. Membrane channel have a reduced pore size. Control size of the entrance to the pore and the ion selectivity at

REVIEW SHEET EXERCISE 3 Neurophysiology of Nerve Impulses NAME: 1. Match each of the definitions in Column A with the appropriate term in Column B. Column A Column B __D__ term that refers to a membrane potential of about -70 mv __F__ reversal of membrane potential due to influx of sodium ions __B__ major cation found outside of a cell __A__ minimal stimulus needed to elicit an action potential __E__ period when cell membrane is totally insensitive to additional stimuli‚ regardless

Na ions outside the cell. The driving force of the action potential is the increase in the concentration gradient because of the increase of Na ions outside the cell. 4. General anesthetics such as ether and chloroform open K+ gated-channels in the brain. What would be the effect of inhaled ether on the generation of action potentials in neurons in the brain of a rat exposed to this anesthetic? Provide a good and brief physiological explanation. In activity 7 you tested the effect of lidocaine

blood’s ability to clot. Blood loss occurs‚ and it happens at a rapid rate. But in 1846‚ a dentist named William Morton had an idea that would help with surgery for decades to come. He used a cloth with pure sulfuric ether on it and had his patients take a deep breath from the cloth. Ether was a prevalent anesthesia‚ but it emitted a foul odor and ignited easily. So in 1847‚ Dr. James Simpson used a different anesthetic‚ chloroform. It had a much more pleasant smell and quickly gained popularity. Almost

to keep light from being absorbed and prevent the discoloration. Since bis-GMA is capable of polymerizing spontaneously under normal storage conditions‚ polymerization inhibitors are added to the matrix. The most common inhibitor is the monomethyl ether of hydroquinone. Another inhibitor that prevents the dimethylcrylate groups on the bis-GMA from polymerizing spontaneously is the use of butylated hydroxytoluene. In order for the matrix to be condensed‚ inorganic filler molecules are added to improve

The test for solubility tagged along the aphorism “like dissolves like” since coconut oil was dissolved in chloroform‚ ether‚ and carbon tetrachloride. The emulsification of fats in coconut oil was also conducted and the only the dilute albumin solution showed a positive effect. The saponification reaction was also conducted which is the focal procedure in the production
