Refractive index of Vanillin and p-bromobenzophenone

Click For Summary
SUMMARY

The refractive index of Vanillin is established at 1.555, although it is temperature-dependent. The discussion highlights the challenge of finding specific temperature data for this measurement. Participants suggest consulting the CRC Handbook for further information, although one user reports difficulty in locating the desired data within the handbook. A common assumption for the temperature is 25°C, which is typically used in refractive index measurements.

PREREQUISITES
  • Understanding of refractive index concepts in organic chemistry
  • Familiarity with temperature effects on physical properties
  • Knowledge of chemical databases and handbooks, specifically the CRC Handbook
  • Basic research skills for locating scientific literature and resources
NEXT STEPS
  • Research the temperature dependence of refractive indices in organic compounds
  • Explore the CRC Handbook for comprehensive data on organic compounds
  • Investigate alternative chemistry textbooks that cover refractive indices
  • Learn about the methodology for measuring refractive index in laboratory settings
USEFUL FOR

Chemistry students, organic chemists, and researchers involved in material characterization and property analysis will benefit from this discussion.

Hi,

I have an organic chemistry assignment identifying an unknown sample. My tutor has asked for the properties (I can find all but refractive index) for vanillin and p-bromobenzophenone.

I found that for Vanillin it is 1.555 but I know that it changes with temperature and I cannot find a temperature for this reading.

I was just wondering if anyone knows a good website or has a good chemistry textbook lying around with this information (I couldn't find it in the VOGEL text...)

Kind regards,

Try the CRC Handbook

I downloaded the handbook and only found dibromobenzophenone.

Any other ideas please?

Where do you download the CRC handbook?

Probably safe to assume 25C.
