C₃H₈O₂ => 4 C₂H₆O₂ + 3 CO₂

What is C₃H₈O₂ and C₂H₆O₂? Propandiol and ethandiol?

mono propylene glycol

[ChenBeier]

Ok, where should the carbondioxide comes from?
What is your question

[islam_haswa]

i need to get c3h8o2 from c2h6o2

[ChenBeier]

Which one
1,2-Propylene glycol or 1,3 Propylene glycol

But above you write in opposit direction
Propylen glycole down to ethylen glycole

Ethylenglycole to Glycolaldehyd HOCH₂CHO
Glycolaldehyd + Methylgrignard => 1,2- Propylenglycol
