WebDimethyl acetylenedicarboxylate (DMAD) is an organic compound with the formula CH 3 O 2 CC 2 CO 2 CH 3. It is a di- ester in which the ester groups are conjugated with a C-C triple bond. As such, the molecule is highly electrophilic, and is widely employed as a dienophile in cycloaddition reactions, such as the Diels-Alder reaction. WebThe Flammable Range (also called Explosive Range) is the concentration range of a gas or vapor that will burn (or explode) if an ignition source is introduced.. Three basic requirements must be met for explosion to take place: flammable substance - fuel; oxidizer - oxygen or air; source of ignition - spark or high heat
