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.
