Standard Test Method for Purity of Propylene Glycol Monomethyl Ether, Dipropylene Glycol Monomethyl Ether, and Propylene Glycol Monomethyl Ether AcetateMore info
1.1 This test method covers the determination by gas chromatography of propylene glycol monomethyl ether (PM), dipropylene glycol monomethyl ether (DPM), and propylene glycol monomethyl ether acetate (PMA).
Note 1—Propylene glycol monomethyl ether (PM) is a mixture of two isomers: 1-methoxy-2-propanol and 2-methoxy-1-propanol.
Dipropylene glycol monomethyl ether (DPM) is a mixture of four isomers: 1-(2-methoxy-1-methylethoxy)-2-propanol is one of the major isomers.
Propylene glycol monomethyl ether acetate (PMA) is a mixture of two isomers: 1-methoxy-2-acetoxypropane and 2-methoxy-1-acetoxypropane.
Dipropylene glycol monomethyl ether (DPM) is a mixture of four isomers: 1-(2-methoxy-1-methylethoxy)-2-propanol is one of the major isomers.
Propylene glycol monomethyl ether acetate (PMA) is a mixture of two isomers: 1-methoxy-2-acetoxypropane and 2-methoxy-1-acetoxypropane.
