Reduction of moisture content form propylene glycol

[Balaji]

Is it possible to reduce moisture content in Polyethylene glycol or propylene glycol by applying vacuum to around 15000 mTorr for 24 hours. If anyone has any idea please let me know

Thank U very much Mr.Douq Huffman. I'm working on a process where 4-6% of moisture is introduced through the ingredients what we add into PEG and propylene glycol but this % of water is detrimental to the product. So by applyin vacuum can I reduce the moisture in PEG and PG solutions
