Making NITRO for my CAR

Link for my Patreon account:   / hexazine   In this video I show you how nitromethane is made in the lab from chloroacetic acid. Fist I prepared 100 ml 40% NaOH solution. I also dissolved 59 grams of NaNO2 in 80 ml of distilled water. In 1 liter 3 necked round bottom flask I placed 100 grams of chloroacetic acid and mixed it with 150 grams of crushed ice. To this mixture I added about 70 ml of the NaOH solution until the pH became basic. The temperature should not exceed 20 degrees during this step to prevent chlorine replacement with hydroxyl group. After the solution was neutralized, I added the NaNO2 solution to the mixture. The flask was heated slowly on an oil bath. When the temperature reaches 60 degrees CO2 starts to come off. Care should be taken so the solution will not bubble over. The nitromethane distills alongside with some water and separates in the receiver. The distillation was continued until no more CO2 and nitromethane came off. The nitromethane layer was separated, and the aqueous layer was saturated with NaCl and distilled. This yielded a few more ml of nitromethane. The combined amounts were washed with saturated NaCl solution and dried with some anhydrous Na2SO4. The salt was filtered, and the liquid distilled. The fraction between 96 and 99 ℃ was collected. Yield 25 grams, 31%. Boiling point 96-99 °C Check out my other videos: Brady’s reagent -    • Making the BRADY'S reagent and TESTING car...   Bromobenzene -    • How to make BROMOBENZENE   Bromine -    • How to make BROMINE   Acetanilide -    • This was once used instead of PARACETAMOL ...   Adipic acid-    • This FOOD ADDITIVE is actually a NYLON pre...   Chlorobenzene -    • How to make CHLOROBENZENE
