It was rather hilarious. But now we have some sodium iodide heating with an organochlorine compound in acetone in a pressure tube. <br />We're feeling lucky! <a href=\"https://mastodon.social/tags/chemistry\" class=\"mention hashtag\" rel=\"tag\">#<span>chemistry</span></a> <a href=\"https://mastodon.social/tags/academiclife\" class=\"mention hashtag\" rel=\"tag\">#<span>academiclife</span></a></p>",
