I have always been puzzled by the way that acetylene produces a higher flame temperature than propane or natural gas, even though it's total heat output is lower. Also, I have never been able to understand the nature of the explosive reaction that can occur when acetylene exceeds
15 psi. This reaction is evidently able to occur without oxygen. I know a little bit about about chemistry, and from what I understand, it seems to me that the triple carbon bond in the acetylene molecule would make it more stable, rather than less, as it seems to be. Does anyone out there have a good explanation of why acetylene behaves the way it does? Thanks much!- posted
