Standard Test Method for
Water Solubility of Auxiliary Solvent for Wood Preserving
Solutions1

This standard is issued under the fixed designation D 3224; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This test method covers the determination of the water
solubility of an organic solvent used as an auxiliary or
cosolvent for pentachlorophenol or other biocides in wood
preserving solutions. Conversely, the solvent solubility in the
water may also be determined. Auxiliary solvents are used to
either formulate high concentrations of penta or other biocides
for shipment of liquid concentrate for subsequent dilution with
an oil, or to boast the biocide solvency of the petroleum
solution when mixed for treating.

1.2 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents

2.1 ASTM Standards:
D 1193 Specification for Reagent Water2
D 3225 Specification for Low-Boiling Hydrocarbon Solvent for Oil-Borne Preservatives3

3. Summary of Test Method

3.1 Fill the 100 mL graduated cylinder with 50 mL of water
and 50 mL of the solvent. After 10 inversions, allow to stand
for 30 min. Then, record the volume at the interface.

4. Significance and Use

4.1 Water solubility of auxiliary solvents is important in
preventing emulsions at the treating plant, and to prevent
precipitation of the biocide from solution due to loss of
solvency (see Specification D 3225).
