Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- other: predicted as per ACD/labs-ChemSpider
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Predicted using ACD/Labs phys-chem module in ChemSpider
- Reason / purpose for cross-reference:
- reference to same study
- Principles of method if other than guideline:
- Initially, using SMILES as the input parameter in the ChemSpider database, the values of the surface tension was predicted for the individual components using ACD/Labs phys-chem module. Finally, the overall surface tension value was calculated on a weighted-average basis using the mole fractions of the individual components.
- Type of method:
- other: Predicted using ACD/Labs physchem module-ChemSpider
- Surface tension:
- 38.89 mN/m
- Remarks on result:
- other: weighted average surface tension value predicted using ACD/Labs phys-chem module in ChemSpider
- Conclusions:
- The weighted average estimated surface tension value for amides, C18 (unsatd.), N,N-bis(hydroxyethyl) using ACD/Labs phys-chem module was determined to be 38.89 mN/m or dyne/cm.
- Executive summary:
The surface tension of amides, C18 (unsatd.), N,N-bis(hydroxyethyl) was predicted using ACD/Labs phys-chem module in ChemSpider. Initially, using SMILES as the input parameter in the ChemSpider database, the values of the surface tension was predicted for the individual components. Finally, the overall surface tension value was calculated on a weighted-average basis using the mole fractions of the individual components.
The weighted average estimated surface tension for amides, C18 (unsatd.), N,N-bis(hydroxyethyl) using ACD/Labs phys-chem module was determined to be 38.89 mN/m.
