PLEASE LET BONNIE KNOW IF YOU BRING A PEROXIDE FORMING OR REACTIVE CHEMICAL INTO THE LAB

From: "Angela Larsen" <angela_larsen@ccmail.uoregon.edu>

Bonnie,

There are two lists here-one of peroxide formers and one of general reactives. Happy hunting. Angela

Peroxide Forming Chemicals

The following chemicals are prone to the formation of peroxides in storage. This list only gives the names of the more common chemicals.

         2-butanol 
         butyl ethyl ether 
         chloroethylene 
         cinnamaldehyde 
         crotonaldehyde 
         dibenzyl ether 
         dibutyl ether 
         1,1-dichoroethylene 
         1,1-diethoxyethane 
         1,2-diethoxyethane

         1,3-dioxane 
         1,4-dioxane 
         dipropyl ether 
         divinyl ether 
         2-ethoxyetbanol 
         ethyl isopropyl ether 
         furan 
         isobutyraldehyde 
         limonene 
         2-methoxyethanol 
         methyl vinyl ether 
         propionaldehyde 
         tetrahydrofuran 
         vinyl acetate 

A single opening of a container will introduce sufficient air to initiate autoxidation - the process of peroxide formation from the reaction of the compound with molecular oxygen. The resulting bivalent O-O group is a strong oxidizing agent. In solution at low concentrations, peroxides can be safely treated and disposed. However, if crystals form, the container is sensitive to thermal and shock hazards. Heating the solution or moving the container can cause an EXPLOSION.

To prevent accidents from peroxidizable compounds, laboratories should assure for their recognition and safe handling. This should include:

1. Identification of all chemicals in storage that may form peroxides.

2. Use of warning labels on these chemicals that record date opened.

3. Ordering of the smallest practicable container size.
