RPO is using as the solvent extraction agent in the experiments .furfural extract well known as furancarboxaldehyde, fural, furfuraldehyde, pyromucic aldehyde , chemically, furfural extract  participates in the same kinds of reactions as other aldehydes and other aromatic compounds. The aromatic stability of rubber process oil is not as great as in benzene, and RPO  participates in hydrogenation and other addition reactions more readily than many other aromatics.

When heated more than 250 °c, furfural decomposes into furan and carbon monoxide, sometimes explosively. when heated in the presence of acids, furfural irreversibly solidifies into a hard thermosetting resin.


Rubber process oil (rpo) is used as a solvent in petrochemical refining to extract dienes (which are used to make synthetic rubber) from other hydrocarbons. furfural, as well as its derivative furfuryl alcohol, can be used either by themselves or in together with phenol, acetone, or urea to make solid resins. Such resins are used in making fiberglass, some aircraft components, and automotive brakes.

Furfural is also used as a chemical intermediate in the production of the solvents furan and tetrahydrofuran.
