Scaled Up Microdroplet Organic Synthesis with Solvent for Beginners

D in chemistry, started an acetone recycling program in the chemistry building in June 2013. She wrote a Sustainable CU Grant to obtain funding for the first fractional distillation system on school, and matching funding was provided by the Chemistry Department and Facilities Managment. This acetone recycling accomplishes an overall efficiency of 76% and has actually saved CU Stone labs over $10,000 since 2013, not to mention the savings on disposal costs for contaminated materials.

Methanol, ethanol, and other solvents can likewise be distilled in fractional distillation systems. In 2016 a second fractional distillation unit was acquired for school with funds supplied by Facilities Management, and it is now in location in the Environmental Health And Wellness Building (EHS). This Site at the Institute for Alpine and Artic Research (INSTAAR) uses ethanol cold traps during its analysis of ice core samples and at the end of the process, they are entrusted a 85-90% watered down ethanol and water solution.

Ethanol reuse has been in effect at CU Stone for a number of years with 120 gallons of ethanol/year being diverted from contaminated materials and being re-used in Biochemistry cell culture, conserving the cell culture facility $1500/yr in avoided ethanol acquiring costs. The ethanol is transferred between the two INSTAAR & Biochemistry Cell Culture labs by Environmental Health & Safety.

The high cost of solvents and the resulting waste cause unneeded costs that can be quickly conserved with an efficient solvent recycling system. For a normal printer, one drum of virgin blanket wash utilized on journalism leads to about two drums of waste that can cost in excess of $300 to get rid of.
