mbeychok, Thanks for the reference, I was looking for a formula for an evaporation rate of a surface spill. This should work out fine for me. Thanks! Why do today what you can put off till tomorrow? Unless, today is your yesterday's tomorrow.

I'm having a problem trying to locate a solid reference for the heat of reaction for ethyl methacrylate and methyl methacrylate. I am trying to calculate my heat of reaction for polymerization of EMA and MMA in my reactor vessels as part of my Risk Managment Plan determination. I have found...

I'm looking to see if anyone has a good reference for Heat of Reaction numbers for ethyl methacrylate and methyl methacrylate, or tables that would include them. I need to calculate my Heat of Reaction for my reactor vessels as part of our determination for the states Risk Management Plan. I...

Yeah, I just saw a similar issue when I was reading up on the CERCLA/SARA regs under the innocent landowner clause. But I didn't know that EPA addressed it again in the FR. That's interesting. I goes to show that EPA is aware of the issue. Did they propose any recommended symmetry between...

Thanks everyone. Katmar & beychok, I figured that is what was going on with the calculations that I have. Thanks for your help. I currently use a program called CONVERT ver 4.08. It's a little older now, but it always gave me good numbers from it. I'll have to check out the other one...

We use ethyl acetate to clean our machines that are used for MMA and EMA filling (methyl methacrylate and ethyl methacrylate). It is very effective. Acetone works really well too, and the fail safe, but with other environmental concerns is Methl ethyl ketone. I hope that helps.

Yeah, I agree with Hotgas, you make the Phase II anything you want from the findings in your Phase I. Obviously you want to catch every type of contaminate that could be on the site, however, budget and time play a role in that determination. The problem I've seen is that if you clean up a...

So the absolute is already taken into account and thus cancel each other out?

Hopefully I am not missing the boat here, but I would love it if someone could help me out. I'm doing some emission factor calculations using API-42. I'm in the middle of converting the Vapor Pressure of toluene and heptane from mm Hg to psia for one of my calculations. Am I correct in...

Considering that the project is almost two years old now, I hope jwolfschlag has an answer by now! :-)
