3. To close the system and thus activate the vacuum, turn the stopcock knob at the far end of the rotovap to align it with the vacuum (ie. turn until the arrow on the knob points straight down towards the attached tubing ie. knob is pointing to the “ON” position). The system is now under reduced pressure. 4.

Heptane - an overview ScienceDirect Topics

Heptane is a seven-carbon aliphatic compound that is a natural constituent in the major paraffin fraction of crude oil and also found in natural gas. Pure n -heptane is a colorless liquid that is highly flammable and lighter than water. It has a gasoline-like odor with an olfactory threshold around 200 mg m −3 (low) and 1280 mg m −3 (high).

Heptane is metabolized to its parent alcohols (mainly 2-heptanol and 3 heptanol, and to a minor extent 1-heptanol and 4- heptanol).The heptanol metabolites are conjugated by glucuronates or sulfates, and subsequently excreted in urine. Heptane is further metabolized at relatively high rates by hydroxylation before being converted to the corresponding keto forms.
