    • A process for the purification of spent process oil, which process comprises mixing the process oil with an additive comprising a liquid mixture of a) at least one alkanola-mine, and b) at least one member selected from the group consisting of alkanoic acids, and alkenoic acids having from 6 to 18 carbon atoms and the melting point/points such that the mixture of a) and b) is liquid at the tem-perature at which the process is carried out, with a pH-value of said mixture of a) and b) in the range of 5 to 8, preferably 6 to 7, and most preferably 6.3, and said mix-ture being substantially insoluble in the process oil, forming a two phase mixture upon mixing, and subsequent separation of the phase with process oil from the phase with said mixture of a) and b) with absorbed contaminants. The invention further provides use of alkanoic acids and alkenoic acids having from 6 to 18 carbon atoms in the preparation of a mixture for the purification of spent process oil as well as the use of alkanolamines. ® KIPO & WIPO 2007
    • 一种用于净化过程油的方法,该方法包括将加工油与包含a)至少一种烷醇矿的液体混合物的添加剂混合,和b)至少一种选自链烷酸, 和具有6至18个碳原子的链烯酸和熔点/点,使得a)和b)的混合物在进行该方法的温度下为液体,所述混合物的pH值为 a)和b)在5至8,优选6至7,最优选6.3的范围内,并且所述混合物基本上不溶于工艺油,在混合时形成两相混合物,随后分离相 使用与所述混合物a)和b)的相的工艺油与吸收的污染物。 本发明还提供了使用具有6至18个碳原子的链烷酸和链烯酸来制备用于净化废加工油的混合物以及使用链烷醇胺。 ®KIPO&WIPO 2007
