I’m in the U.K. and as such struggle to get clean solvents , I’ve just got some 99.5%heptane but it’s showing as having sulphur <2ppm(didn’t show on website) …. I’ve done a search on here and seen you can use copper to remove this …
Could I just add copper scrubbies to the heptane before I use it ?
Will <2ppm sulphur matter once distilled and used for carts??
What copper is Best to use if needed?
If not able to put in heptane how best to use it??
Thanks in advance
Yep that’s the general plan…but … I’ve no rotovap ,hoping to get most heptane out either in a table top distiller(not sure if this will work) or hot plate with stirrer then distill to remove any remaining volatiles / heptane(it boils @98deg c at atmospheric pressure).
from what i’ve read people use alkanes for their CRC … so i guess your answer lies in what your willing to set up equipment wise and what you can get away with safely. i can’t get ALL the heptane out when i do LLE and then rotovap so i throw my vac as hard as i can. get my water bath up to 80c and then when i redistill it pulls out the residual heptane with my terp/volatiles before i get into heads fraction. good luck my friend.
