acid has a melting point of 121-125C. The melting point of recovered benzoic acid was 109-115C. There is a noticeable broaden and depression of the melting point which points to impurities. For the benzoic acid in particular the impurity could have been the ice cold water. To combat this next time, essential time should be allotted for the suction filtration to the component to dry and also a heating lamp could have been used to rid the benzoic acid of water. Next, benzocaine has a melting point of

dibromide The measured melting point of experimental dibromostilbene was 228.0-231.0°C, a slightly depressed value from the theoretical

Introduction Acid-base extraction is a very useful technique in organic chemistry. It is used to separate organic compounds from each other. The idea is that most of organic compounds will be more soluble in organic solvents than they are in water (1). The extraction, in its most basic form, will result in unequal distribution of solute between two immiscible (not forming one mixture when added together) solvents (2). Since both of the solvents are immiscible, two separate layers will be formed

Substance 1 – Copper sulfate REFERENCE substance 1 had a melting point below 100oc due to the weak intermolecular forces between the molecules, these forces were able to separate when heat below 100oc was added to them (ref). The substance did not conduct electricity in any form, however it was noted during the experiment that both probes could not reach the substance, so the conductivity results were disregarded for substance 1. From the low melting point, it was presumed that

acid were provided in the laboratory experiment text. Erythro-2,3-dibromo-phenylpropanoic acid held a melting point of 204°C, while threo-2,3-dibromo-3-phenylpropanoic acid held a melting point of 95°C. These two products had vastly different melting point values, which made it clear to observe the product created at the end of the experiment. Once the product was determined due to comparison of melting points, the stereochemistry could be

benzoic acid through base extraction then purify these substances via recrystallization. In addition, we were able to analyze and deduce how efficient we were in purifying the substance through IR Spectroscopy, NMR spectroscopy, and by comparing melting points. This experiment proved to be partially successful. Through base extraction, we were successful in separating benzoic acid from Acetanilide. The strong base help in separating the two layers in the separatory funnel. Sodium benzoate was found

Introduction Extraction is a technique that is commonly used to separate mixtures, despite whether the components are solids or liquids. One of the most well-known examples of extraction is the brewing of tea or the making of coffee. Every pot of coffee or cup of tea involves solid-liquid extraction. The soluble flavor and caffeine are extracted from the solid tea leaves or ground coffee beans into hot water (the solvent). Insoluble plant material is left behind in the tea bag or coffee filter

benzoate illustrates this type of reaction. The objective of this experiment is to synthesize methyl m-nitrobenzoate from methyl benzoate and will be purified by recrystallization with methanol. To make sure that the correct product is formed, the melting point and tlc profile are obtained. For the results, the mass of the conical flask was 89.222g, adding
