B Reaction of 1,3-Cyclopentadiene and Maleic Anhydride

3-Cyclopentadiene is a mildly toxic, foul-smelling, and volatile substance. Prepare and use it in a hood if possible avoid inhaling its vapors. Keep the diene cold at all times to minimize vaporization and dimerization. 

Be certain that all joints in the apparatus are tight before heating dicyclopen-tadiene to produce the monomer. 

3-cyclopentadiene and organic solvents used are highly flammable, so use flameless heating.
