    • Synthetic oil that contains wholly or partly of dialkylbenzenes and/or partially or totally hydrogenated dialkylbenzenes. The synthetic oil according to the invention can also be used as an oil base or oil base additive and comprises at least one dialkylbenzene and/or at least one partially or totally hydrogenated dialkylbenzene and meets the general chemical formula: R1—A—R2 in which R1 and R2 represent alkyl groups and A is a benzene core and/or a cyclohexane core and/or a cyclohexene core and/or a cyclohexadiene core and is characterized in that it contains between 1 and 20% by weight or ortho isomers and in that at least one of the alkyl groups is attached for the most part to group A by carbon 2 of the aliphatic chain. The two alkyl groups are preferably attached for the most part to group A by carbon 2 of the aliphatic chain.

    • A process for oligomerising olefins in an organic feed containing at least one olefin comprises two steps with different types of catalysis. The cut to be treated containing at least one olefin (Cn) is introduced via line 1 into a reaction zone R1 where in a first step it undergoes catalytic oligomerisation, either of a liquid phase homogeneous type, or heterogeneous with a solid support. The effluent produced is sent via line 2 to a heat exchanger E1 traversed by a cold liquid. The effluent is thus cooled before being sent via line 3 to a second reaction zone R2 where it undergoes catalytic oligomerisation in a liquid-liquid two-phase medium. After reaction, the effluent is fed via line 4 to a zone L1 where it is washed. After washing, the hydrocarbon fraction is sent via line 5 to separator S1. The fraction containing the unreacted olefins (Cn) is separated from the oligomer product fraction produced, this fraction Cn is evacuated from the apparatus via line 6, and the fraction containing the oligomer products is evacuated via line 7.
    • 在含有至少一种烯烃的有机进料中使烯烃低聚的方法包括具有不同催化类型的两个步骤。 待处理的包含至少一种烯烃(Cn)的切割物通过管线1引入到反应区域R1中,其中在第一步骤中,它经历液相均相型的催化低聚反应,或与固体支持物异相。 产生的流出物通过管线2输送到由冷液体穿过的热交换器E1。 因此,流出物在通过管线3送入第二反应区R2之前被冷却,在第二反应区R2中,其在液 - 液两相介质中经历催化低聚。 反应后,流出物通过管线4进料至其中洗涤的区域L1。 洗涤后,烃馏分通过管线5送至分离器S1。 将含有未反应的烯烃(Cn)的馏分与所生产的低聚物产物馏分分离,将馏分Cn通过管线6从装置排出,含有低聚物产物的馏分通过管线7排出。
