Refractive index of Vanillin and p-bromobenzophenone

  1. Jun 5, 2010 #1

    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.
