Description
United METHOD FUR PRODUCING DRYING OILS AND THE OIL S PRQDUCED Josef Weiss, Vallingby, Sweden, assignor to Richard Nilsgon Aktiebolag, Stockholm, Sweden, a corporation of weden No Drawing. Application August 6, 1956 Serial No. 602,439
Claims priority, application Sweden November 7, 1955 6 Claims. (Cl. 106-252) This invention has for its objects a method for producing drying oils and the oil so made.
Many methods are known for producing drying oils and for the improvement of such drying oils.
Apart from the use of metallic driers which only act as catalysts during the drying process the object of all known methods is not only to accelerate the drying, but also to improve the film properties of the oil. In all known processes this effect is attained by encroaching on the chemical structure of the glyceride molecule. A few examples of these methods are.
(l) Producing of standoils by boiling drying oils with or without the use of vacuum,
(2) Conjugation of the isolated double bonds according to different methods,
(3) Accumulation of glycerides with more unsaturated fatty acids by selective extraction or by other methods,
(4) Transformation of non-drying castor oil into a drying oil with conjugated double bonds,
(5) Removal of saturated glycerides by a splitting process, removing the saturated acids and re-esterfying the unsaturated acids by means of polyalcohols, etc.
The object of these processes is to achieve one or several of the following improvements:
(a) Acceleration of the drying process,
(b) Avoiding after-stickiness of the films,
(c) Improving the water-and weather resistance, etc.
The methods mentioned require expensive equipments, a great consumption of energy and chemicals, and they involve very complicated and expensive processes.
It is also known to improve drying oils by mixing them with organic Al-compounds, for instance aluminiumalcoholates but these compounds cause a poor stability of the mixture.
The inventor has found, that additional improvements can be attained by mixing a natural drying or natural nondrying oil of vegetabilic or animalic origin with a synthetic oil, produced by condensation of one or more fatty acids with an organicaluminium compound in enolic form, i. e. a compound in which Al is partly linked to oxygen of an enolic group, for instance according to the U. S. patent application of Kurt Hans Reisinger, Serial No. 258,539 filed November 27, 1951, which became abandoned on or about January 10, 1957, or its continuation-in-part-application Ser. No. 600,729 that was filed June 30, 1956. The last named patent application corresponds to British Patent No. 761,536, complete specification published November 14, 1956. As
2,871,135 Patented Jan. 27, was
found in the patent one mole of the aluminum-alcoholate reacts with one mole of the enalic compound according to the equation:
The enolized aluminum-alcoholate then reacts with 2 moles of a fatty acid thus forming a drying oil the constitution of which is explained by the replacement of the 2 moles alcohol by 2 moles fatty acids while the enolic compound remains in its place bonded to the aluminum via the O-bridge.
The mixture of the natural and the synthetic oils is carried out either at room temperature or at an elevated temperature. Mixing may be elfected by agitating or stirring until the components are intimately mixed and from a homogenous composition. Driers such as lead-, cobaltand/or manganese salts, and/or pigments, may be added in known manner.
The action of the addition of the synthetic oils, for instance on linseed oil and other drying natural oils consists in a considerable acceleration of the drying process of the oils so that the duration of this process may be reduced to about /5-% of the drying time of the original drying oils used in the mixture. Thus the non drying oils will be converted into drying oils having shorter drying times than boiled linseed oil. In addition to this advantage, there are also obtained important improvements of the film properties. The water and weather resistance of the oil is considerably improved by the addition of said synthetic oil. The films obtained from linseed oil and other drying oils swell in water and are spoiled after a few days. The films of expensive isomerized linseed oils are dim already after having'been exposed to the influence of water for one day. The films produced by oils according to the pres ent invention remain clear even after having been exposed to water for months and they do not swell in water. The pigmentation properties, the adhesion, the flexibility etc. are excellent.
The oil composition according to the invention is compatible with all other raw materials conventionally used in producing lacquers and varnishes.
Certain valuable properties of the oils and their films can be attained by changing the ratio between the quantities of the natural oil and the synthetic oil. Among these properties which are attained the range of viscosity of the oils which are produced may vary from a low viscosity oil like the known natural oils to the viscosity of standoils. As an entirely new property for drying oils of this kind can be mentioned, that all films of oils produced according to the present invention are repellent to fungi.
The following table gives a survey on the possibilities and the most important properties of different oils within the scope of the invention.
