Technical Details & Test Data
- Foam Height Data
The foaming properties of DeTROPE SA-45 were determined via modified Ross-Miles, graduated cylinder shake test. The foam heights are presented in the following charts compared to sodium xylene sulfonate (SXS-40) and are reported as millimeters of foam present initially, at 30 seconds, at 60 seconds and after 2 minutes.
- Hydrotrope Foam Heights (1% surfactant 'as-is' in DI water)
- Hydrotrope Foam Heights (2% surfactant 'as-is' in 5% active NaOH)
- Cloud Point and Foam Height Data
To determine hydrotroping capabilities, a series of cloud point tests were performed. The hydrotrope was solubilized in caustic or alkaline electrolyte solution to which a 9.5 mole nonyl phenol was added. Each sample was heated to the temperature at which the non- ionic clouds out of solution. The cloud point temperatures are reported in the following charts. The higher the cloud point temperature, the more efficient the hydrotrope. The control is a 9.5 nonyl phenol in each caustic and alkaline electrolyte solution with no hydrotrope added. The hydrotroping capabilities of DeTROPE SA - 45 at higher levels of NP-9.5 show similar trends.
- Hydrotrope Cloud Points (1% NP-9, 1.5% hydrotrope as-is)
Key:
- NaOH = Sodium Hydroxide
- SMP = Sodium Metasilicate Pentahydrate
- TKPP = Tetrapotassium Pyrophosphate
- SXS-40 = Sodium Xylene Sulfonate 40% active
- Hydrotrope Cloud Points (1% NP-9, 1.5% hydrotrope)
- Hydrotrope Cloud Points (3% NP-9, 2.5% hydrotrope)
SMP = Sodium Metasilicate Pentahydrate / TKPP = Tetrapotassium Pyrophosphate / SXS-40 = Sodium Xylene Sulfonate 40%
- Hydrotrope Cloud Points (5% NP-9, 3.75% hydrotrope)
- Hydrotrope Foam Heights (1% hydrotrope in DI water)
- Hydrotrope Foam Heights (2% hydrotrope in 5% active NaOH)
- Hydrotrope Foam Heights (2% hydrotrope in 5% active phosphoric acid)
Hydrotrope Cloud Point Comparison (5% NP-9 w/ 3.75% hydrotrope (as-is))
Cloud Points of Test Solutions: 5% NPE-9, 3.75% Hydrotrope (by wt.), 91.25% Electrolyte
- Cloud Points of Test Solutions: 1% NPE-9 + 1.5% Hydrotrope (as-is), 97.5% Electrolyte
- Dynamic Surface Tension
Dynamic surface tension for DeTROPE SA - 45 was conducted at 1.0% and 2.0% by weight in deionized water at ambient temperature. Compared to SXS-40 at 2.0% by weight, DeTROPE SA - 45 provides considerably lower surface tension.
- Dynamic Surface Tension at Ambient Temperature
- Corrosion Inhibition Properties
Metal coupons were partially submerged in a solution containing from 0.25% - 1.0% by weight of DeTROPE SA - 45 in hard water (100ppm as CaCO₃ and 71ppm as CaCl₂) and stored in sealed glass jars at room temperature. The top halves of the panels were exposed to the vapor phase.
