The Objective The purpose of this experiment was to learn and preform an acid-base extraction technique to separate organic compounds successfully and obtaining amounts of each component in the mixture. In this experiment, the separation will be done by separatory funnel preforming on two liquids that are immiscible from two layers when added together. The individual components of Phensuprin (Acetylsalicylic acid, Acetanilide, and Sucrose as a filler) was separated based upon their solubility and reactivity, and the amount of each component in the mixture was obtained. Also, the purity of each component will be determined by the melting point of the component. Structures/Reactions/Properties Substance Structure M. F. M.W. m.p.

  • Explains that the experiment was to learn and preform an acid-base extraction technique to separate organic compounds successfully and obtaining amounts of each component in the mixture.
  • Explains how they mixed phensuprin and dichloromethane in a 125 ml erlenmeyer flask until the solid dissolved. sucrose was washed with 5 ml of dichlormethan.
  • Describes the process of removing the acetylsalicylic acid from the solution.
  • Describes the process of extracting the phensuprin from the acetylsalicylic acid, methylene chloride, and sucrose.
  • Explains that extraction was used to separate a mixture of three solids to their individual components based on their acid-base properties.
  • Explains that acetanilide remained in the organic layer and acetylsalicylic acid transferred to the aqueous layer.

The mixture was poured through a weight filter paper and Sucrose washed with a 5ml of dichloromethane. The resulting solid was left in a breaker to dry for one week, to be measured. Left it in the drawer to dry out for a week and weighted it to find the sucrose amount recovered amount. - Fluted paper weight: 0.98 - Fluted paper weight + Sucrose weight: 1.416 - Sucrose weight: 1.416 - 0.98 = 0.436 g - Melting point range of Sucrose: 190 C – 169 C = 21 C Isolating the Acetylsalicylic …show more content…

Extraction is a separation method that is often used in the laboratory to separate one or more components from a mixture. Sucrose was separated at the beginning because it is the most immiscible and it’s strongly insoluble. Next Acetylsalicylic Acid was separated which left Acetanilide alone. Variety steps could have led to errors occurring. For example the step of separation, when dichloromethane layer was supposed to be drained out, it could be possible some aqueous layer was drained with it. Which could make the end result not as accurate. Also errors could have occurred if possibly some dichloromethane was not drained out. Both way could interfere with end result of figuring the amount of each component in the mixture. The solids percentage were 22.1% more than the original. That suggests that solids weren’t separated completely which clarifies the reason the melting points that were recorded were a slightly lower than the actual component’s melting point. The melting point for Acetylsalicylic Acid is 136 C but that range that was recorded during the experiment was around 105 C to 118 C. The melting points were slightly lower than the literature value. Sucrose was the purest among all component due to its higher melting point which follows the chemical rule that the higher the melting point the more pure the component
