Analysis of Products.
« on: July 01, 2005, 10:51:56 AM »
Dear All,
I am in the middle of nowhere. I have had a reaction to synthesize
tributyl phosphate. The reactants were phosphorus oxychloride,pyridine
and n-butanol. Now that the reaction is complete. I want to get the
organic layer separated in the separating funnel analysed. I want to
know how much quantities of tributyl phosphate, dibutyl phosphate,
monobutyl phosphate, water and butanol are present in the separated
organic layer. I have searched for all th available conventional methods of analysis
but they are qualitative. I want to know if there is any method that
gives us the percentage of the above mentioned entities. Any sort of
help will be appreciated.
Regards.

GC-MS should do iit without to much of a problem. MAkes sure you dilute it enough though. P=O compounds can sometimes stick to the column and then it takes a thorough baking to get them off..

1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.

Sorry to message again. OK all I want is to know the concentrations of all the products and byproducts in the organic layer. Will GC/MS give me the percentage of all these components?

It won't tell you the percentage but you can calculate it from the data.
