- Example I 500 grams of calcium stearate were dispersed in 2000 ml. of water by passing through a Manton-Gaulin homogenizer. 180 grams of FeCl were then dissolved in 500 ml. of water. The temperature of the calcium stearate slurry was raised to about 150 F. and the FeCl solution at room temperature was added over a period of 30 min-, utes with moderate agitation. The slurry mixture became thick as the FeCl was added, but eventually thinned out on completion of the addition. Agitation was continued for about 30 to 40 minutes after completion of FeCl addition. The product was then filtered on a water Buchner filter, the filtration being quite rapid. The product, which was ferric stearate, was dried at F.
- Example II grams of calcium stearate were slurried in 500 ml. of water by means of a Manton-Gaulin homogenizer. Two or three drops of Stearox A]. were employed in order to wet the calcium stearate. 29 grams of ZrCl, were added with rapid agitation over a 10 to 12 minute period. The temperature of the slurry mixture rose from 79 F. to 102 F. The resultant product, which was zirconium stearate, was filtered and washed with about 500 ml. of water.
- Example 111 Example IV 2500 ml. of water, 111 grams of lime, 6 grams of Stearox AJ. and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were weighed into a 1500 ml. beaker. 38 grams SbCl, were then dissolved in 150 ml. of water. The SbCl solution was then added to the calcium stearate slurry. A temperature rise of from 86 F. to 99 F. was observed. Agitation was continued for one hour after completion of the addition. The resultant product, which was antimony stearate, was filtered and dried at 140 F.
- Example V 2500 ml. of water, 111 grams of lime, 6 grams of Stearox A.l., and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were weighed into a 1500 ml. beaker. 29 grams of ZrCl, were then added to slurry. A temperature rise of 86 F. to 108 F. was observed. Agitation was continued for about one hour after completion of the addition of ZrCl.,. The product, which was zirconium stearate, was filtered, washed with 500 m1. of water and dried at about 140 F.
- Example VI 2500 ml. of water, 111 grams of lime, 6 grams of 3 Stearox AJ., and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were then weighed into a 1500 ml. beaker. 44 grams of SnCl were then dissolved in 100 ml. of water. The SnCl, solution was added to the calcium stearate slurry; a temperature rise of from 86 F. to 92 F. being noted. The slurry was agitated for approximately one hour after completion of the addition of the SnCl, solution. The resultant product, which was tin stearate, was then filtered, washed with 500 ml. of water and dried at 140 F.
- Example V11 2500 ml. of water, 111 grams of lime, 6 grams of Stearox AJ. and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were added to a 1500 ml. beaker. 30 grams of SbCl were then added to the slurry; a temperature rise of from 86 F. to 113 F. being noted. The slurry was agitated for approximately one hour after completion of the addition of the SbCl The resultant product, which was antimony stearate, was filtered, washed with .500 ml. of water and dried.
- Example VIII 500 grams of calcium stearate were dispersed in 200 ml. of water. 238 grams of ferric nitrate were dissolved in 500 ml. of water. The calcium stearate dispersion was then heated to about 140 F. and the ferric nitrate solution added thereto with agitation. 'Ihe agitation was continued for a period of about thirty minutes, during which time the reaction went to completion. The product, which was ferric stearate, was filtered on a Buchner funnel and air dried at 140 F.

Description
United States Patent Ofiice 3,078,288 Patented Feb. 19, 1963 This invention relates to double decomposition preparation of heavy metal soaps.
Metallic soaps are commonly prepared by a double decomposition process involving formation of a sodium soap followed by the replacement of the sodium cation to form a heavy metal insoluble soap.
While a double decomposition process as indicated above is suitable for the preparation of certain water insoluble metallic soaps, it has not been found to be suitable for the preparation of certain other heavy metal soaps.
It is an object of this invention to prepare heavy metal soaps by a double decomposition process.
It is a further object of this invention to prepare pure heavy metal soaps by means of a double decomposition process wherein the product may be easily washed free of undesirable contaminants.
I have now discovered that it is possible to produce heavy metal soaps by a double decomposition process comprising slurrying an insoluble calcium soap of a fatty acid in water and then adding a water soluble salt having an anion which has the ability to form water soluble calcium salts and preferably is selected from the group consisting of nitrate anion, chloride anion, iodide anion, bromide anion and acetate anion, and a metallic cation of a metal selected from groups III, IV, V, VI-A, and VIII cations. The fatty acid is preferably a fatty acid having a carbon chain length of from 9 to 22 atoms and more specifically a fatty acid selected from the group consisting of azelaic acid, stearic acid, lauric acid, myristic acid, hydroxy-stearic acid, palmitic acid, erucic acid, pelargonic acid, eleostearic acid, oleic acid, and linolenic acid. The cation of the salt is preferably a cation selected from the group consisting of cations of the rare earth metals, aluminum, titanium, zirconium, tin, lead, vanadium, antimony, chromium and iron. It should be understood that in order to maintain certain of the fatty acids and more specifically eleostearic acid, oleic acid and linolenic acid in a solid state, it is necessary to cool these acids below room temperature. The reaction may be illustrated as follows, wherein FA represents a fatty acid radical:
In general, stoichiometric quantities of reactants are preferred although quantities of from 1.0 to 1.1 equivalents of water soluble salt may be employed per equivalent of calcium soap.
It has been found that reaction of the calcium soap with a water soluble heavy metal salt occurs under the most favorable circumstances where a dispersion of the calcium soap has been obtained by passing the soap through a homogenization unit. The homogenization operation appears to have the effect of exposing sufiicient surface area of the calcium soap to insure reaction of the water soluble heavy metal salt. The intimate mixture which can be had with the homogenizer also results in the reduction of the amount of water which must be used in the slurry. The term homogenizer as employed herein means homogenization apparatus well known in the chemical industry and of a type wherein the material to be homogenized is passed through a very small opening under high pressure. It is prefered to force the material to be homogenized through the homogenizer against sutficient back pressure to reduce the particle size sufliciently to disperse the reaction product. This can be done by one or a plurality of passes of the material through the homogenizer.
The following specific examples of preparations prepared according to the process of this invention are given for purposes of illustration and are not to be considered as limiting the spirit and scope thereof:
Example I 500 grams of calcium stearate were dispersed in 2000 ml. of water by passing through a Manton-Gaulin homogenizer. 180 grams of FeCl were then dissolved in 500 ml. of water. The temperature of the calcium stearate slurry was raised to about 150 F. and the FeCl solution at room temperature was added over a period of 30 min-, utes with moderate agitation. The slurry mixture became thick as the FeCl was added, but eventually thinned out on completion of the addition. Agitation was continued for about 30 to 40 minutes after completion of FeCl addition. The product was then filtered on a water Buchner filter, the filtration being quite rapid. The product, which was ferric stearate, was dried at F.
Example II grams of calcium stearate were slurried in 500 ml. of water by means of a Manton-Gaulin homogenizer. Two or three drops of Stearox A]. were employed in order to wet the calcium stearate. 29 grams of ZrCl, were added with rapid agitation over a 10 to 12 minute period. The temperature of the slurry mixture rose from 79 F. to 102 F. The resultant product, which was zirconium stearate, was filtered and washed with about 500 ml. of water.
Example 111 Example IV 2500 ml. of water, 111 grams of lime, 6 grams of Stearox AJ. and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were weighed into a 1500 ml. beaker. 38 grams SbCl, were then dissolved in 150 ml. of water. The SbCl solution was then added to the calcium stearate slurry. A temperature rise of from 86 F. to 99 F. was observed. Agitation was continued for one hour after completion of the addition. The resultant product, which was antimony stearate, was filtered and dried at 140 F.
Example V 2500 ml. of water, 111 grams of lime, 6 grams of Stearox A.l., and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were weighed into a 1500 ml. beaker. 29 grams of ZrCl, were then added to slurry. A temperature rise of 86 F. to 108 F. was observed. Agitation was continued for about one hour after completion of the addition of ZrCl.,. The product, which was zirconium stearate, was filtered, washed with 500 m1. of water and dried at about 140 F.
Example VI 2500 ml. of water, 111 grams of lime, 6 grams of 3 Stearox AJ., and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were then weighed into a 1500 ml. beaker. 44 grams of SnCl were then dissolved in 100 ml. of water. The SnCl, solution was added to the calcium stearate slurry; a temperature rise of from 86 F. to 92 F. being noted. The slurry was agitated for approximately one hour after completion of the addition of the SnCl, solution. The resultant product, which was tin stearate, was then filtered, washed with 500 ml. of water and dried at 140 F.
Example V11 2500 ml. of water, 111 grams of lime, 6 grams of Stearox AJ. and 658 grams of stearic acid were mixed with agitation. 710 grams of the resultant calcium stearate slurry were added to a 1500 ml. beaker. 30 grams of SbCl were then added to the slurry; a temperature rise of from 86 F. to 113 F. being noted. The slurry was agitated for approximately one hour after completion of the addition of the SbCl The resultant product, which was antimony stearate, was filtered, washed with .500 ml. of water and dried.
Example VIII 500 grams of calcium stearate were dispersed in 200 ml. of water. 238 grams of ferric nitrate were dissolved in 500 ml. of water. The calcium stearate dispersion was then heated to about 140 F. and the ferric nitrate solution added thereto with agitation. 'Ihe agitation was continued for a period of about thirty minutes, during which time the reaction went to completion. The product, which was ferric stearate, was filtered on a Buchner funnel and air dried at 140 F.
The process of this invention results in a superior heavy metal soap product. It is believed that this product is superior to the heavy metal soap products produced by the sodium soap reactant double decomposition process of the prior art in that calcium soap is not hydrolyzed to the extent that the sodium soap is by the presence of certain salts of heavy metals. The fact that hydrolysis is not produced in a calcium soap results in a product being produced which may be easily washed free of the resultant soluble calcium salts without being hindered by the presence of large amounts of metal hydrate and free fatty acid.
