Plasticized sulfur compositions suitable for use as road-marking material are comprised of elemental sulfur, plasticized sulfur, a viscosity control agent and solid filler material. The plasticized sulfur is deodorized by distilling a solvent stripping agent having an initial boiling point greater than 350. degree. F. and a boiling range less than 100. degree. F. The solid filler material preferably includes substantially equal quantities of silica and calcium carbonate. Titanium dioxide is also included in the solid filler. Both white and yellow-colored paints can be manufactured according to the present invention. The yellow paint includes a yellow pigment in addition to the titanium dioxide, silica and calcium carbonate filler material. In one embodiment, lead chromate is used as the yellow pigment. In another embodiment, an organic yellow pigment, such as an arylide yellow, is used as the pigment.

In a process for hydrogenating an olefinically unsaturated dinitrile in which the reactants in a solvent are passed through a ruthenium on alumina catalyst, the improvement which comprises operating at a reduced pressure during the early contact with the catalyst and slowly increasing the pressure over an extended interval of time to normal operating pressure. This startup procedure greatly increases the run length (life) of the catalyst bed.
