No, in opposite case reaction flask can explode with very upset consequences.

You can pure HCl 37% acid and stir it until ph 6.5-7, if you can't count.
G.PattonMaster, Why do we need this ph๐Ÿ™๐Ÿป?

After adding the hydrocloric acid instead of yellow I got a bluish color what could this be attributed to?

Reagents:
  • 1-Phenyl-2-nitropropene (P2NP; cas 705-60-2) 1000 g;
  • Methanol (MeOH) 10 L;
  • Sodium borohydride (NaBH4) 470 g;
  • Hydrogen peroxide (H2O2) 30% 6 L;
  • Potassium carbonate (K2CO3) 1800 g;
  • Hydrochloric acid (HCl) 37% aq;
  • Dichloromethane (CH2CI2) 5 L;
  • Sodium hydroxide (NaOH) 5 L 25% aq;
  • Distilled water (H2O) 5 L;
Equipment and glassware:

Reaction scheme:
Synthesis:
1. 1-Phenyl-2-nitropropene 1000 g is dissolved by methanol (MeOH) 10 L in 20 L flask.
2. The reaction mixture is cooled to 0 ยฐC by an ice/salt bath with good stirring.
3. Sodium borohydride (NaBH4) 470 g is added to reaction mixture in small portions with a constant stirring in order to control reaction temperature below 15 ยฐC.
4. The ice/salt bath is removed after an exothermic reaction end.
5. The solution is stirred at room temperature for 2 h.
6. Then, the solution is cooled to 0 ยฐC in ice/salt bath again.
7. Hydrogen peroxide (H2O2) 30% 6 L and potassium carbonate (K2CO3) 1800 g are added into the reaction flask.
8. The solution is stirred for 24 h at room temperature.
9. Next, hydrochloric acid (HCl) 37% aq is poured into the mixture dropwise to reach pH 6.5-7. The reaction is exothermic, CO2 is released (caution!).
10. The mixture is
extracted with dichloromethane (CH2CI2) 5 L, extract is washed with sodium hydroxide (NaOH) 5 L 25% aq. and distilled water (H2O) 5 L.
11. Dichloromethane (CH2CI2) is
distilled off under vacuum to give a clear phenylacetone (P2P, cas 103-79-7) yellow oil. The yield is 70%.

Can I use chloroform for extraction?

Borehydride is not available in my country currently
I now have tin chloride and ethyl acetate. How do I arrange the steps? I need advice from someone who tried reducing p2np using tin chloride.
