Answer to Question #25106 in Organic Chemistry for Viktorija

Question

What volume of air is needed to oxidize methanol if I need to get 1 ton solution which includes 40 % formaldehyde.

Answer 1

1 ton of solution = 1 000 kg of solution
1 000 kg of solution includes 40 % of formaldehyde and it is:

m = 1 000 * 40/100 % = 400 kg = 400 000 g

Reaction for this process is :

2CH₃OH + O₂ ---> 2CH₂O + 2H₂O

Now it is possible to calculate volume of O₂

v 400 000
2CH₃OH + O₂ ---> 2CH₂O + 2H₂O

22.4 2 * 30

v = 400 000*22.4 /(2 * 30) = 149333.3 L
