HelloIf currently doing a research job concerning a process for the preparation of propionic acid from calcium carbide, and it turns out that one of the steps involved is the preparation of acetylene from calcium carbide. Wikipedia says, and pretty much every book seems to agree, that the main way to manufacture acetylene is to make the calcium carbide react with water; which is why I find it so odd that I have been unable to find an article on the subject. WIPO has something about the preparation of acetylene, but they use a completely different method. I know is supposed to be a very old and well known reaction, but I can't find any articles describing it in detail. żDoes anyone knows where can I find a modern study of this process?? Before someone suggest it, I know there is a nice article about it in "how products are made". However, I don't like it for two reasons: (1) I'm looking for a much more technical approach, and (2) "How products are" web page as a reference fails to look serious in a scientific paper  Anyway, if anyone has some info about it or knows where I can find it, it would be really appreciated.
CaC2 + H2O > C2H2 + CaOH
Hmmm... I can't believe I didn't even know thw formula for calcium hydroxide. My mistake so it should be CaC2 + 2H20 > C2H2 + Ca(OH)2Cheers lightarrow
