Start with 250mL of ammonia and add to it 100mL of methyl ethyl ketone. Stir and then slowly add 1/4 mole equivalent of sodium hypochlorite based
bleach. if using 10% bleach then about 186g is needed. If using 6% household bleach about 310g is needed. As the bleach is added the reaction will
heat up and bubble vigorously, slow down the addition if it’s bubbling too much. After all the bleach is added, keep stirring until the mixture
stops bubbling. Then stop stirring and allow it to stand for a few hours until so until it separates into two clear layers. The top layer is methyl
ethyl ketazine. Separate it using a seperatory funnel or by careful decantation. In a separate container, add 20mL of concentrated sulfuric acid to
100mL of water and stir. Then add the hot solution directly to the ketazine and keep stirring. The hydrolysis will generate crystals of hydrazine
sulfate.
