    $\begingroup$ This is a simple reaction that should work easily at much lower pressures. Have you tried using a different batch of catalyst? Have other researchers used this batch successfully recently? $\endgroup$

  • $\begingroup$ I agree, the few hydrogenations I have done were at low pressure and ambient T. The reaction was smooth and fast, monitored by the lowering of H2 pressure. Research some methods in the library not the internet $\endgroup$

  • $\begingroup$ You started with a nitrogen atmosphere. Did you purge with hydrogen? Parr apparatus should be in a hood. $\endgroup$
