AROMATIC OIL AND PROCESS FOR MANUFACTURE |
摘要 |
An aromatic oil having an aniline point less than 120.degree.F, a mutagenicity index based on The Modified Ames Test of less than 2.0, a benzene, naphthalene and methyl substituted benzenes and naphthalene individual component concentrations less than 100 wppm, and a clay gel aromatics fraction content of at least 50 weight % based on aromatic oil, said aromatics fraction characterized in that it has a naphthenebenzenes and dinaphthenebenzenes content of at least 50 volume % based on aromatics fraction. The invention also relates to a process for preparing the aromatic oil which comprises the steps of selective solvent extraction, selective distillation and two-stage hydrotreating with removal of hydrogen sulfide and/or ammonia. The aromatic oils are useful in agricultural formulations due to their low environmental impacts.
