Hello,
Regarding the odor, may I suggest DOI: 10.1021/ed064p726, Figure 2 (note, a
two-hole stopper is used). Sorry, I cannot help with your actual question.

Subject: [DCHAS-L] Experience with 4-methylcyclohexene Lab
Hi everyone,
I am reaching out to see if anyone has experience with the dehydration of
4-methylcyclohexanol to 4-methylcyclohexene lab in the Pavia et al lab
textbook. The reaction seems to call for an awful lot of H2SO4 in addition
to H3PO4 and is giving off several noxious odors. I would like to recommend
getting rid of the H2SO4 but am concerned about whether this may cause
unwanted organophosphates to be produced. I am concerned as I cannot figure
out what kind of byproduct or decomp products we may be getting.
Does anyone have any thoughts on this? I am not an organic chemist, so
maybe I am just overthinking this one too much.
Monique
