DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a process for producing an additive for lubricants, as well as for aqueous fuel mixtures and heating media, in which an alkaline aqueous solution of an inverted cane sugar as the main component with a content of a hydrocarbon and an alcohol is heated and then cooled, the aforementioned use possibilities and the use as an impregnating material for air filters of motor vehicles and random combustion systems.
PRIOR ART
The process of the aforementioned type is known from DE-OS No. 3,205,594. According to the specific details of the latter a mixture of 50% caustic soda solution, petroleum, acetic acid, glycerol, an ethanol/propanol mixture and a main mass constituted by an inverted liquid sugar, particularly based on cane sugar, is kept for 10 minutes at a temperature of approximately 60.degree. to 65.degree. C. Following cooling, an agent is formed which, added to mixtures of water, alcohol and gasoline (e.g. in a volume ratio of 1:5:4) in a quantity of a few parts per thousand, yields a liquid, which can be used in random combustion systems, as well as in internal combustion engines of motor vehicles. Although this known process leads to extremely advantageous results, it requires a careful matching of the aforementioned components. Thus, particularly favourable results are obtained with an additive prepared in the following way. Firstly a mixture of 20 to 45% by weight of 50% caustic soda solution, 3 to 15% by weight of petroleum, 3 to 15% by weight of 5% acetic acid, 25 to 80% by weight of glycerol and 20 to 45% by weight of a mixture of ethanol and propanol is prepared. This mixture is subsequently mixed with 10 times the quantity of a 75% aqueous inverted liquid sugar (cane sugar). This is heated to the effective additive of aqueous fuels, etc. in the described manner. It is considered possible to increase the effectiveness of such an additive by adding traces of calcium sulphate hemihydrate (CaSO.sub.4 1/2H.sub.2 O).
DISCLOSURE OF THE INVENTION
The problem of the invention was to so improve the aforementioned process that a simple and more flexible production of the sought process product is made possible.
According to the invention this problem is solved in that use is made of cane sugar with a degree of inversion of approximately 50 to 80%, particularly approximately 55 to 75% and is heated to approximately 75.degree. to 100.degree. C. until a red shade forms.
Thus, the essence of the invention is that use is not made of completely inverted cane sugar. Use is in fact made of a degree of inversion of approximately 50 to 80%, particularly approximately 55 to 75% and in preferred manner approximately 60 to 70%, whilst a level of approximately 66% in especially preferred manner leads to the desired results. With respect to the choice of the special inverted cane sugar, the invention constitutes a selection invention.
It is vital in conjunction with this selection to continue the heating of the starting mixture until a red shade has formed. This important fact can also not be gathered from prior art. It is advantageous that this red shade is obtained as quickly as possible, which can be achieved by heating the starting mixture to a temperature of more than approximately 75.degree. C., preferably more than approximately 80.degree. C. and especially more than 90.degree. C. Particularly favourable characteristics are obtained with respect to the process product if it is kept for some time roughly at boiling temperature and in particular approximately 100.degree. C., in order to bring about the indicated red shade. A temperature of 100.degree. C. should not be exceeded. Following heating, cooling takes place to ambient temperature.
The starting material for the inventively sought product is always a concentrated aqueous solution of cane sugar with the indicated degree of conversion. The concentration of this cane sugar is advantageously at least 50% by weight and in particular close to the degree of saturation. Particularly favourable results are obtained if the
