Patented Sept. 24, 1957 2,807,553 STABILIZED Marat soar coMPosirioNs Alfred Fischer, Bronx, N. Y., assignor, by mesne assignments, to Heyden Newport Chemical Corporation, a corporation of Delaware No Drawing. Application .Iuly 1a, 1955, Serial No. 522,865
lltl Claims. (Cl. ice-24s) This invention relates to oil-soluble metal salt or soap compositions useful in several arts for various purposes, such as, for example, paint and varnish driers, vinyl resin stabilizers, fungicides, catalysts, lubricant additives, bodying agents, etc.
The metal soaps useful alone or in combination as paint and varnish driers are principally the cobalt, manganese, lead, calcium, zinc, iron and vanadium soaps of certain organic acids. The fungicidal metal soaps include among others the soaps of copper, zinc, cadmium and mercury. Metal soaps useful alone or in combination as vinyl resin stabilizers are principally the soaps of barium, strontium, calcium, cadmium, zinc, tin and lead. Similar examples of metal soaps may be shown as being useful as catalysts, lubricant additives, etc. It also becomes apparent that a single metal in the form of its soap is useful in several applications. For example, zinc soaps are not only useful as driers, fungicides and vinyl resin stabilizers as previously stated, but also as pigment wetting agents, etc.
The metal soaps referred to are generally waterinsoluble solids. They are used commercially as solutions in non-polar, organic solvents, such as mineral spirits, Stoddards solvent, naphtha, kerosene, benzene, toluene, xylene and other solvents boiling at a temperature below 500 F. These solutions are added to the vehicle or organic medium for which they are intended. For example, cobalt, manganese and lead soaps are usually employed as driers in compositions containing drying oils and vehicles, such as linseed oil, oil-modified alkyd vehicles, etc. Barium, cadmium and zinc soaps may be employed as stabilizers for vinyl resin compositions containing plasticizers, such as dioctyl phthalate, dioctyl sebacate, tricresyl phosphate, etc. To be commercially useful, these metal soap solutions should dissolve easily, rapidly and with a simple mixing operation in the ultimate composition. Some of the other desirable physical characteristics of metal soap solutions upon which their commercial utility depends, are as follows:
1. They should be stable indefinitely in storage. Metal soap solutions usually are somewhat unstable and tend to precipitate during storage.
2. They should have a relatively low viscosity at high metal soap concentration so as to permit ready admixture with the vehicle or organic medium for which they are ultimately intended. In many cases, soap solutions at high metal concentration have an objectionably high viscosity and must be diluted to reduce viscosity. This means added cost as well as the incorporation of a larger proportion of extraneous material. In other cases, metal soap solutions which have an initially low viscosity tend to increase in viscosity on aging.
3. They should mix freely, quickly and easily at room temperature with the vehicles for which they are intended. Further, after they are incorporated into the ultimate compositions, they should notprecipitate during storage. Many soap solutions, even those of low viscosity, are incompletely soluble, or dissolve after a long period of time, or require vigorous and prolonged agitation to effect solution in the vehicle for which they are intended. Other soap solutions, after having dissolved in the ultimate vehicle or composition, sludge out during storage, that is, a portion of the active metal soap constituent precipitates and thereby becomes inactive.
Various attempts have been made in the past to obtain these desirable or ideal characteristics of metal soap solutions.v For example, the incorporation of free organic acid and certain alcohols have been suggested. However, their use is attcnded by many disadvantages such as volatility, relatively low degree of efficiency, adverse affects on the rate of drying in the case of the drying metal soaps, etc.
' The principal objects of this invention are to provide metal soap solutions which are of low viscosity, both initially and after aging,which are stable indefinitely, and which dissolve readily in the vehicles for which they are intended. Other objects and advantages of this invention will become evident as the description proceeds.
I have found as a result of protracted experimentation that the foregoing objects may be accomplished and that stabilized metal soap solutions may be provided by the incorporation in said solutions of polyoxyalkylene glycols of the formula H(OCHR1CHR2)OH, wherein R1 and R2 are either hydrogen atoms or alkyl groups and x equals at least 2. The polyoxyalkylene glycols of, this invention, when used to the extent of /2 part to 18 parts per parts of the metal soap solution, produce metal soap solutions of indefinite storage stability, of low viscosity, both initially and after aging, and of excellent solubility in vehicles, such as drying oils, e. g., linseed oil, plasticizers, e. g., dioctyl phthalate, etc. Some of the polyoxyalkylene glycols that I have successfully employed as stabilizing agents are diethylene, triethylene, tetraethylene, dipropylene, tripropylene and tetrapropylene glycols. I have found that, when x==3 in the foregoing formula, the glycols so described, namely, triethylene glycol and tripropylene glycol, are particularly effective in accomplishing the objects of this invention.
In addition, these triglycols improve the drying properties of cobalt, manganese, lead and calcium soaps and improve the stability of solutions of these drier soaps in linseed oil and other vehicles. While the mechanism by which these glycols operate is not as yet known, the particular efiectiveness of the triglycols suggest that the symmetrical structure of the latter, which may be written as follows is responsible, perhaps by forming complex compounds with the metal soaps.
The metals which may beemployed in the preparation of the metal soap solutions of this invention are the alkaline earth metals, e. g., barium, strontium, calcium, and the heavy metals, e. g., cobalt, manganese, lead, cadmium, iron, vanadium, zinc, nickel, tin, copper and mercury.
The organic acids which may be used with any of the foregoing metals to form the metal soap solutions of this invention include naphthenic acid, tall oil acids, rosin and rosin oil acids, unsaturated acids, such as oleic, linoleic and linolenic acids, and branch-chained saturated acids containing at least 8 carbon atoms, such as Z-ethylhexoic acid, isooctoic acid, etc. Combinations of the aforementioned acids, as well as other organic acids capable 'of forming oil-soluble metal soaps or salts, have been successfully employed in this invention. For the purposes of this invention and without distinguishing effect I have used the terms soap and salt synonymously.
The soaps resulting from the combination of the afore mentioned metals and organic acids may be dissolved in hydrocarbon solvents, such as mineral spirits and others previously mentioned, to form the metal soap solutions of this invention.

In the foregoing examples, some of the ways of combining the polyoxyalkylene glycols with the metal soaps have been defined, but it will be understood that the glycols may be combined with such metal soaps at any stage during their preparation or subsequent to the formation of the metal soaps. In practice, they may even be introduced into the metal soap-vehicle composition.
I have hereinbefore referred to different heavy metals and alkaline earth metals but have not attempted to give examples of all of said metals. However, the tests which have been made show very definitely that all of them may be employed in the carrying out of this invention. In many cases in the examples difierent metals may be substituted for those referred to therein, so that it has not been considered necessary to duplicate examples merely to show the employment of such different metals.
It will be apparent from the foregoing examples that the polyoxyalkylene glycols of this invention perform different functions. In some cases the function is singular in its nature while in other cases they perform a plurality of functions. Some of the several functions of the said polyoxyalkylene glycols may be briefly summarized as follows:
1. to render the metal soap solutions indefinitely stable,
2. to render metal soaps soluble in vehicles wherein they are insoluble in the absence of such glycols,
3. to improve materially the solubility of metal soap solutions in vehicles in which they are only partially soluble in the absence of such glycols,
4. to improve the stability of metal soap solutions in the vehicles for which they are intended,
5. to reduce the viscosity of unstabilized metal soap solutions, and,
6. to improve the effectiveness of metal soaps in their various end uses, e. g., to improve the drying properties of drying metal soaps.
In the foregoing description I have set forth the preferred embodiments of this invention but the examples herein given are to be understood as illustrative, only, and not as defining the limits of this invention which is to be understood as fully commensurate with the appended claims.
Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:
