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.

Abstract. Acetonitrile is a high-polarity organic solvent widely used in various chemical industries and laboratories. It was once used in consumer goods such as cosmetics. Acetonitrile is readily absorbed through the skin, by inhalation and by ingestion, and acute poisoning and even fatal effects are possible via these routes.

Solvent Recycling and Azeotropes

Another common binary azeotrope found in solvent recycling is acetonitrile and water. This is a common mixture used for HPLC analysis. Acetonitrile boils at 81.6 C and water boils at 100 C. The mixture forms an azeotrope which boils at 76.1 C and which is composed of 86% acetonitrile and 14% water. There are also azeotropes between three ...

Apr 11, 2010 Acetonitrile (CH 3 CN, ACN) is described as a relatively nontoxic, highly volatile and aprotic polar organic solvent. ACN is one of the most stable nitriles and its hydrolysis in water is extremely slow. However, under environmental conditions, this substance is readily biodegraded by several strains of bacteria common in sewage sludge, natural waters and soil.
