Hello, fellow chemists

I am seeking a practical method of oxidizing primary alcohols in the
presence of ether functionality, applicable to bulk production.

The chemistry, generally, is

HOCH2CH2O[CH2CH2O]nCH2CH2OH ==> HOOCCH2O[CH2CH2O]nCH2COOH

To be applicable it has to be:

1) inexpensive reagents/catalysts
2) practical solvents (carbon tet, methylene chloride, and chloroform are
out, as are HMPA or CS2)
3) reasonable conditions: -10 to 200 'C, vacuum to 100 psig.
4) no oxygen in the presence of flammable solvents.

I would appreciate any leads, even if the references do not satisfy all of
the above conditions.

Thanks in advance. Respond to jchubb$##$qci.com
