horza, cool , thanx for the insight. I attached the the paper on" Palladium Chloride Catalyzed Decomposition of Vinyl Acetate in Acetic Acid" in full. I'm interested to see if this answers your question on PdCl2 roll in the reaction. Palladium chloride catalyzed decomposition of vinyl acetate in acetic acid 1-1.pdf

ok , its taken some time for me to get back to this. i attached a file for you horza so hopefully you can let me know what you think. that is if AA in necessary. I came across another post in a different forum that stated . "55% of vinyl acetate is catalytically hydrolyzed to equal amounts of acetaldehyde and acetic anhydride under mild conditions and rapidly. The experimental conditions employed 2% molar ratio of PdCl2 (0.005 mol) for vinyl acetate (0.1 mol) in 60 ml glacial acetic acid stirred 1 hr at 40-80 C. producing 0.048 mol acetaldehyde and 0.05 mol acetic anhydride. " i was wandering if you could verify this, it seems much safer and all that would be left to do after the reaction would be to filter out the PdCl2 then distill off the vinyl acetate and the acetic acid. What do you think?

horza, thank you for taking the time to assist me and explain this in greater detail i really appreciate the help. I'll get the detail of wich groups im trying to acetyllate to you as soon as possible , some time tomorrow most likely. As for the glass I'm guessing you use Durex rather than Pirex in applications involving that much pressure. I can order durex though through my distributor, once the GAA has reached 800 c does it need to remain at that temp for a specific amount of time ? Or is the process complete once the temp. is achieved evenly throughout the solution? Thank you again for the info and for the link!!!

i'm aware of that, but at least i understand the process and feel comfortable with it. i'm not stupid just "slow" , i have a hard time with picturing something I've never seen before.

i mistakenly used the term acetate where acetyl should have been. would this result from using GAA as well, it was my understanding that i need AA .Thanx for the info on AA but im afraid i dont quite understand.what would be added as a dessicant while heating to 800 c? how would you suggest heating it in a sealed invirament? and would using a ketene lamp be easier? I'm a experienced borosilicate glass blower and can fabricate almost any glass equipment that would be needed. I'm "slow" at initially grasping things and usally need them spelled out, hence the name. Thanx again

Yes there are many reasons for monitoring AA and i have no intention of playing around with any pretty red flowers that stand on a very thin leg. However I am very fond of certain other herbs and the legalization of medical uses for them. That being said i have no need for copious sums of AA simply enough to satisfy my curiosity of forming acetates out of certain c****binoids. I hope this answers your question and you'll help me understand this process a little better.

i can purchase the acetic acid with relative ease but purchasing acetic anhydride , well i would rather avoid the unwanted attention from big brother. I've been told that running acetone through a ketene lamp produces acetic anhydride. so Guitar are you saying that the production is minimal and is better done with acetic acid? I've also read that it can be acheived by dehydrating acetic acid at a molecular level by means of heating to a temp of 800 c. If this is correct it would be much easier for me to do. I could do so in an annealing oven to reduce the fire hazard. My question with this method besides the obvious ":does it work?" is what to rehydrate with. Everything Ive read refers to it as a liquid and H2O would put me back at the beginning again and it reacts in alcohol as well.

suppose heating to 800 c is not a problem. the applications that call for AA suggest that it is in a liquid form. how do you then return the dehydrated AA to a liquid when it reacts with H2O converting itself back into acetic acid. What liquid should be used for re hydration?

I'm looking for suggestions on acetic anhydride productions at home. Maybe a way of making a home made ketene lamp? I don't have an extensive knowledge of chemistry and this makes the most sense to me.
