Standard Specification for Dipropylene Glycol Monomethyl Ether

ABSTRACT
This specification covers dipropylene glycol monomethyl ether (DPM). Dipropylene glycol monomethyl ether shall conform to the requirements specified for the following: (1) assay content, (2) distillation range defined by the initial boiling point and dry point, (3) apparent specific gravity, (4) platinum-cobalt scale color, (5) water content, and (6) acidity (free acid as acetic acid). The sampling and test methods to determine conformance to the specified properties are given.
SCOPE
1.1 This specification covers dipropylene glycol monomethyl ether (DPM). Note 1 Dipropylene glycol monomethyl ether (DPM) is a mixture of isomers, the predominant isomer being 1-(2-methoxy-1-methylethoxy)-2-propanol.
1.2 The following applies to all specified limits in this standard; for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 For specific hazard information and guidance, consult the supplier's Material Safety Data Sheet for materials listed in this standard.
