摘要：
A heat transfer oil, comprising a base oil made from a waxy feed, wherein the base oil has a low pour point, low aromatics, and defined cycloparaffin composition. The heat transfer oil has high AIT and VI, and is an ISO viscosity grade. A process to prepare heat transfer oil, comprising: hydroisomerization of wax feed to make fraction(s) of base oil having low pour point, defined cycloparaffin composition, and high ratio of monocycloparaffins to multicycloparaffins; and blending the fractions with
