Saturated NaCl solution\nwas added to the distillate to \u201cpull\u201d the aqueous layer out as a diluent for\nthe NaCl (aq). To further separate the aqueous and organic layers, the\ndistillate was washed with a small amount of dichloromethane and then shaken\nvigorously (venting frequently). Upon settling, the denser organic layer was\ndrained from the separatory funnel into an Erlenmeyer flask. This process was\nrepeated 3 times. This crude extraction was based on the principle: \u201clike\ndissolves like\u201d or \u201clike is miscible in like\u201d.<\/p>\n\n\n\n<p><em>Oil purification<\/em>.\nAnhydrous Na<sub>2<\/sub>SO<sub>4<\/sub> was added to the crude oil (repeated if\nnecessary) to absorb any remaining water. When the mixture looked \u201cgranular\u201d or\nturbid, the dried dichloromethane\/organic solution was transferred to a\npre-weighed boiling flask (boiling chip inside). A rotary evaporator removed\nthe rest of the dichloromethane leaving a purified clove oil product.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"847\"
