Ammonium hydroxide (0.5 mol/L) is added to the pectin concentrate to adjust pH to 10.5 and kept at room temperature for 3 h. After allowing to stand for 3 h, 95% ethanol at the identical volume (identical to the volume of industrial pectin extract) is added, and an appropriate amount of hydrochloric acid is added to adjust pH to 5. Reacts extremely violently with dimethyl sulfate [NFPA 491M 1991]. At 15.6 °C (60.1 °F), the density of a saturated solution is 0.88 g/ml and contains 35.6% ammonia by mass, 308 grams of ammonia per litre of solution, and has a molarity of approximately 18 mol/L.
