Separation of Amines and Carboxylic Acids Using Extraction
Initially have a sample of a water-insoluble, neutral organic compound dissolved in 50 mL methylene chloride that may be contaminated with:
-Organic carboxylic acid and/or
-Organic amine base
The organic neutral compound will be a solid while the acid/base impurities can either be solids or liquids.
Devise a laboratory procedure to separate the organic neutral compound from the potential acid/base impurities and obtain a maximum yield of purified material. The sample must be in crystalline form.
All of the organic compounds can be recrystallized from 95% ethanol
At a certain temperature and pressure 2.8 L of N2 reacts with 4.2 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure, will be produced?
what is the molarity of an aqueous solution containing 360g of glucose in 2.0L of solution.
Determine how many grams of solute would separate if the quantity of the solvent is 129 grams if a saturated solution of ammonium nitrate at 75 °C is cooled to fifteen degree Celsius?
