RUBBER PROCESSING OIL,FURFURAL EXTRACT,RPO
What is Aromatic Rubber Processing Oil?
Aromatic Rubber Processing Oil 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.
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.
Usage of RPO
Aromatic 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 furfural 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.
What are the different grades of RPO?
RPO different types have two general grades:
RPO with a viscosity of 30 to 50 are titled as heavy (high viscosity) grade.
How is RPO made?
The RPO is produced by using extraction of lube oil fraction with a solvent having a selective affinity for aromatics. The extraction conditions are determined so that the extraction yield is regulated to a predetermined requirement defined by the PCAs content of the lube oil fraction.
