Description

The invention relates to the paint industry and can be used to produce a drying oil used in the manufacture of oil paints.

The purpose of the invention is to improve the color of the varnish and utilize secondary raw materials. .

As an oxidized vegetable oil, linseed oil contains sunflower or soybean oil. As a desiccant, lead-manganese desiccant.

As the aliphatic sirnyk alcohol, the drying oil contains oleic alcohol, dodecyl alcohol, primary alcohols C, o-C, e, C 2-C, 6, secondary alcohols C, (, - C, g, alcohols of the Cg-Cjo fraction isolated from neomyp All of them are secondary raw materials in the production of surfactants. Primary alcohols are obtained by catalytic hydrogenation of fatty acids or ethers. Secondary alcohols are obtained by oxidizing paraffinic: hydrocarbons in the presence of boron-containing compounds. Alcohols from neatly produced are obtained by fractionating unwashed "; - .

Table 1 presents the characteristics of the aliphatic fatty alcohols used.

Drying oil is prepared as follows.

Fatty alcohols are introduced into the oxidized oil with stirring, the desiccant, for example, lead-manganese, white spirit, is stirred for 10 minutes.

Table 2 presents the composition of the drying oil and its properties.
