SU95204A1 - A method of making synthetic linseeds for printing inks by treating shale oils - Google Patents

Description

For the manufacture of printing inks, linseed polymerized liners, alkyd (tin) synthetic linseed oils, solutions of various resins (for example, rosin esters, phenol-aldehyde) in vegetable dyes1 to petroleum non-drying oils, as well as solutions of bitumen and non-drying, as well as bitumen and non-drying oils, are commonly used as binders. oil non-drying oils

Only flax polymerized drying oils, synthetic drying oils, and solutions of various emulsified flax, etc., vegetable oils are suitable for making illustrative printing inks that require fast and durable drying on glazed, dense, slightly absorbable paints.

In the paint and varnish technique, a method of making synthetic drying is known, and their drying oil by treating shale oil with formalin in the presence of an acid catalyst. The resulting phenol-pharmaldehyde resin resulting from this treatment

dehydrated and dissolved in volatile solvents.

Unlike the limestone method, a new method is proposed for the manufacture of synthetic drying oil from shale oil and gasoline shale residue cracking to dehydrate them by evaporation and to introduce a mixture of formalin and ammonia or hexamine in the form of an aqueous solution. The reaction temperature is set depending on the viscosity required of the linseed oil and on the composition of the original shale oils and shale gas cracking residues, but not higher than 105 if not higher than the temperature at which the light oil shale boils begin to boil. The formation during the reaction of the vapor and gases is removed from the reaction sphere by an exhaust device, for example, a vacuum pump.

Synthetic linseed oil from dry oils and gasoline cracking residues, which was obtained in this way, is a valuable substitute for natural drying oil and other drying drying oils for the manufacture of printed inks of black and dark colors.

Subject invention

A method for making synthetic linseeds for printing inks by treating shale oils (for example, the shale cracking residuals is lifeless) with formalin or urotronin nrn heated, so that the resulting formaldehyde and resin obtained as a result of such processing imparting the desired printing properties to the solvents, dissolve in the original shale oils to the desired viscosity and without the introduction of any volatile solvents.
