Kromě Lo+rou jsou také známy přísady do paliv, které obsahují oxidy železa a jsou s palivem dokonale promíšeny. Optimální obsah oxidů železa v palivu je 0,01 až 0,1 vztaženo na hmotnost paliva; umožňuje se tím snížení vytváření sazí o 21 Protikouřové působení takové přísady je však malé a nedostatkem je rovněž, že taková přísada vykazuje nedostatek protismykových vlastností, což omezuje její široké použití.Fuel additives are also known which prevent smoking and reduce the level of harmful substances in exhaust gases, especially diesel engines. In addition to Lo +, fuel additives which contain iron oxides and are intimately mixed with the fuel are also known. The optimum iron oxide content of the fuel is 0.01 to 0.1 based on the weight of the fuel; This makes it possible to reduce soot formation by 21 However, the anti-smoke action of such an additive is small and it is also a drawback that such an additive exhibits a lack of anti-skid properties, which limits its widespread use.

Získaná směs se dekantuje tak dlouho, až se již neoodělují síranové ionty, to znamená, až se již voda nezakaluje v dalších dvou hodinách po přidání chloridu barnatého- Přidá se kapalné prostředí do získané úsady oxidu měďnatého. nejlépe olej o nízké viskozitě, v množství 1,5 hmotnostních dílů kapalného prostředí na dva hmotnostní díly oxidu měďnatého- Složky se důkladně promísí, do směsi se přidá povrchově aktivní činidlo, nejlépe kyselina olejová, k dosažení dvou hmotnostních dílů oxidu měďnatého, 1,5 hmotnostních dílů kapalného prostředí a 0,9 hmotnostních dílů povrchově aktivního Činidla. Do této směsi se přidává kapalné prostředí za nepřerušovaného míchání až do dosažení dvou hmotnostních dílů oxidu měďnatého. 20 hmotnostních dílů kapalného prostředí a 0,9 hmotnostních dílů povrchově aktivního Či4 n idla.A solution of 34.5 g of sodium hydroxide in 600 ml of water is prepared and filtered. A solution of 100 g of blue vitriol in 400 ml of water is prepared and also filtered. Heat to 70 ° C, add the solution of blue vitriol to sodium hydroxide solution and stir for 15 minutes and pour into water and make up to volume. two liters to four liters. The mixture obtained is decanted until the sulphate ions are no longer separated, i.e., the water no longer becomes cloudy within the next two hours after the addition of barium chloride. The liquid medium is added to the copper oxide deposit obtained. preferably low viscosity oil, in an amount of 1.5 parts by weight of liquid medium per two parts by weight of cuprous oxide. The ingredients are mixed intimately, a surfactant, preferably oleic acid, is added to the mixture to achieve two parts by weight of cuprous oxide, 1.5 parts by weight. parts by weight of liquid medium and 0.9 parts by weight of surfactant. To this mixture is added a liquid medium with continuous stirring until two parts by weight of copper oxide are reached. 20 parts by weight of a liquid medium and 0.9 parts by weight of a C14 surfactant.
Při dosažení dfikladného pronísení se přidá kapalné prostředí, nejlépe aminobenzoové kyselina až do dosažení dvou'hmotnostních dílů koloidních částic Čistého kovu, 2 až 47 hmotnostních dílů kapalného prostředí a 2,5 x 10~2 až 5,0 x 10-2 hmotnostních^ dílů aminobenzoové kyseliny.To achieve a thorough mixing, a liquid medium, preferably aminobenzoic acid, is added until two parts by weight of the pure metal colloidal particles, 2 to 47 parts by weight of the liquid medium and 2.5 x 10 -2 to 5.0 x 10 -2 parts by weight are obtained. aminobenzoic acids.
Takto získaná směs částic koloidní disperze mědi se přidává do mazadel, do chladicích kapalin pro třískovém obrábění a do paliv.The mixture of particles of colloidal copper dispersion thus obtained is added to lubricants, to coolants for machining and to fuels.
