Process for preparing an aromatic oil and non-discoloring rubber composition containing said oil
Abstract
Abstract A NOVEL LIGHT-STABLE RUBBER PROCESS OIL CONTAINING 4585 PERCENT OF AROMATIC HYDROCARBONS IS OBTAINED IN HIGH YIELD FROM A 40-10,000 SUS (AT 100*F.) NAPHTHENIC DISTILLATE BY A TWO-STEP AROMATIZATION PROCESS. IN THE FIRST STEP, WITH A SULFACTIVE CATALYST THE SULFUR AND NITROGEN IN THE OIL ARE GREATLY REDUCED AND THE AROMATIC CONTENT INCREASES. IN THE SECOND STEP, WITH NI OR NOBLE METAL CATALYST, THE AROMATIC CONTENT IS FURTHER INCREASED AND THE PRODUCT OIL HAS GOOD COLOR STABILITY WHEN AGED IN THE PRESENCE OF ULTRAVIOLET LIGHT. OILS PRODUCED BY THE PROCESS ARE ESPECIALLY USEFUL WHEN COMPOUNDED WITH NATURAL RUBBERS AND SYNTHETIC ELASTOMERIC POLYMERS (E.G., NEOPRENE, GRS) WHICH EXHIBIT IMPROVED PROCESSABILITY AND PHYSICAL PROPERTIES WHEN COMPOUNDED WITH OILS OF HIGH AROMATICITY.
