摘要：
The invention is directed to a medicinal white oil composition comprising a base oil obtainable by a process wherein the following steps are performed,
(a) hydrocracking/hydroisomerisating a Fischer-Tropsch product, wherein weight ratio of compounds having at least 60 or more carbon atoms and compounds having at least 30 carbon atoms in the Fischer-Tropsch product is at least 0.2 and wherein at least 30 wt% of compounds in the Fischer-Tropsch product have at least 30 carbon atoms,
(b) separating the product of step (a) into one or more gas oil fractions and a base oil precursor fraction,
(c) performing a pour point reducing step to the base oil precursor fraction obtained in step (b), and
(d) separating the effluent of step (c) in two or more base oil grades.
