Methyl 1,2,3,4-tetrahydro-6-naphthyl ether
Cas Number:
1730-48-9
Molecular formula:
C11H14O
IUPAC Name:
6-methoxy-1,2,3,4-tetrahydronaphthalene
Test material form:
other: liquid
Details on test material:
Test item: Methoxy-tetraline
CAS number: 1730-48-9
Batch number: S41214K
Physical state: Liquid

Storage: At a temperature of 15 to 30 °C

Results and discussion

pH value
pH value:
5.5
Temp.:
27.2 °C
Concentration:
10 g/L
Remarks on result:
other: emulsion

Any other information on results incl. tables

As the water solubility of test item is less than 1 w/v % (10 g/L) so an emulsion was resulted.

After stirring for an hour the two phases were allowed to divide for 5 minutes. The pH was measured from the water phase of the emulsion.

Applicant's summary and conclusion

Conclusions:
The measured pH of 1 w/v % (10 g/L) Methoxy-tetraline (CAS No. 1730-48-9) emulsion was 5.50 at 27.2 °C.
