Výohozí dikarboxylové kyselina má v molekule 3^ atomů vodíku a vzniká dimerizaoí kyseliny linolová nebo kyseliny linolěnová. Ková sloučenina podle vynálezu je připravitelná dispergaaí melaminu v příslušné dimerní mastné kyselině při teplotě 2V až 200 °C, přičemž je vhodná používat dispergátorů s vysokým střižným efektem. **inou oestou je působení vodného roztoku melaminu na dimerní mastnou kyselinu za zvýěených teplot, obvykle blízkých teplotě bodu varu směsi.Nejvýhodnějším postupem přípravy je dispergace, neboť se získáPreferably, the dicarboxylic acid has 3 hydrogen atoms in the molecule and results in dimerization of linoleic acid or linolenic acid. The metal compound of the present invention is obtainable by dispersing melamine in the appropriate dimer fatty acid at a temperature of 2 ° C to 200 ° C, and it is suitable to use high shear dispersants. ** Another oesthetic treatment is the action of an aqueous melamine solution on a dimeric fatty acid at elevated temperatures, usually near the boiling point of the mixture.

200 2BS produkt použitelný bez dalších náročnějších úprav. V některých případech může být melanin znečištěn melamem nebo vyššími kondenzačními produkty, které se z reakční směsi odstraní nejlépe filtrací při teplotě 80 až 150 °G.200 2BS product usable without further demanding modifications. In some cases, melanin may be contaminated with melam or higher condensation products, which are preferably removed from the reaction mixture by filtration at 80 to 150 ° C.
PříkladExample
Pro přípravu sloučenin podle vynálezu se použije nožový dispergátor objemu 1,5 1 s 4 000 ot/min. Předloží se 1 mol dikarboxylové mastné kyseliny a*za míchání se vsype 126,1 g melaminu. Směs se intenzivně disperguje a současně vyhřívá na teplotu 80 až 85 °0. Dispergace se nechá probíhat 15 až 20 minut do vymizení částic melaminu. Směs se filtruje s přetlakem 0,2 až 0,4 MPa při 80 °C.For preparing the compounds of the present invention, a 1.5 L blade disperser at 4000 rpm was used. 1 mol of dicarboxylic fatty acid is introduced and 126.1 g of melamine are added under stirring. The mixture was vigorously dispersed while heating to 80-85 ° C. The dispersion is allowed to proceed for 15 to 20 minutes until the melamine particles disappear. The mixture is filtered at a pressure of 0.2 to 0.4 MPa at 80 ° C.
