Glass Ball as Bullet Solubility System: 1,5-Dimethylnaphthalene with Water

   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) 1,5-Dimethylnaphthalene; C12H12; [571-61-9]  NIST Chemistry WebBook for detail

Original Measurements:
   Mackay, D.; Shiu, W.Y., J. Chem. Eng. Data. 1977, 22, 399-402.

   Temperature = 25 °C

Prepared By:
   M.C. Haulait-Pirson

Experimental Remarks:

   The solubility of 1.5-dimethylnaphthalene in water at 25°C was reported to be 3.38 mg(1) dm–3 sln and x1 = 3.77 × 10–7.

The corresponding mass percent calculated by the compiler is 3.38 × 10–4 g(1)/100 g sln.

Experimental Data:   (Notes on the Nomenclature)
   A saturated solution of (1) in (2) was vigorously stirred in a 250 mL flask for 24 hrs. and subsequently settled at 25°C for at least 48 hrs. Then the saturated solution was decanted and filtered and 50-100 mL extracted with approximately 5 mL of cyclohexane in a separatory funnel. After shaking for 2 hrs. the cyclohexane extract was removed for analysis. An Aminco-Browman spectrophotofluorometer (American Instruments Ltd.) was used for analysis. Many details are given in the paper.

Source and Purity of Materials:
   (1) Aldrich Chemicals, Eastman Kodak, or K and K Laboratories, commercial highest grade; used as received.
   (2) doubly distilled.

Estimated Errors:
   Solubility: ± 0.04 mg(1) dm-3 sln (maximum deviation from several determinations).
