Address for Service: Complete specification for the invention entitled Solubilizing Process for the Manufacture of a Copper Oxinate Preparation".
90 0 0 The following statement is a full description of this invention, including the best method of performing it known to me:- 1- 5020 -la- The present invention is concerned with a solubilization process, namely a process for the manufacture of a copper oxinate preparation which is soluble in organic solvents and, respectively, of a copper oxinate solution in an organic solvent.
o.C Copper oxinate (oxine copper), i.e. the complex of Cu (II) with 8-hydroxyquinoline. and its fungicidal 15 properties have been known for a long time and have been described in numerous publications Pesticide Manual.
o 0.
8th Ed., page 622). It is also known that copper oxinate is soluble in water under strongly acidic conditions (pH For certain uses it is, however, advantageous or necessary to provide solutions of copper oxinate in an organic solvent. Such solutions have hitherto been o° prepared by solubilizing copper oxinate with nonylphenol or 2-ethylhexanoic acid Ni salt Patents 2,651,379, 2,561,380 and 2,608,556). However, nickel salts as well as 25 nonylphenol belong to the toxicologically-hazardous substances which, for this' ceason, must no longer be used in certain countries.
It has now surprisingly been found that copper oxinate can be dissolved in organic solvents using certain phosphoric acid esters as solubilizers.
The phosphoric acid esters which are usable as solubilizers are liquid substances which correspond to the 3 formula As/23.5.89 2 0

RO-P-OR' (I)
S
S S I 4i 1 ft i t iI I I r i i i:i r i Ii t t 1 i I wherein R and R' represent hydrogen or an alkyl group with up to 13 carbon atoms, whereby at least one of the symbols R and R' is an alkyl group.
The compounds of formula I above are accordingly known 15 monoesters and diesters of phosphoric acid.
The process in accordance with the invention for the manufacture of a copper oxinate preparation which is soluble in organic solvents and, respectively, of a copper oxinate solution in an organic solvent accordingly comprises using as a solubilizer a compound of general formula I above in which R and R' have the above significance.
25 The alkyl groups R and R' can be straight-chain or branched, whereby straight-chain alkyl groups can contain 1-8 carbon atoms and branched alkyl groups can contain up to 13 carbon atoms, i.e. 3-13 carbon atoms. Examples of such alkyl groups are methyl, ethyl, propyl, isopropyl.
30 butyl, isobutyl, amyl, hexyl, 2-ethyl-hexyl, octyl, isooctyl and isotridecyl.
Mixtures of monoesters and diesters of formula I above can also be used as the solubilizer.
Especially preferred solubilizers are monoesters and diesters of formula I in which R and/or R' signifies 2-ethyl-hexyl and mixtures of such monoesters and diesters.
00., *666 9 00 01 9 *0 3 The weight ratio between copper oxinate and solubilizer can vary within a wide range.
Copper oxinate and solubilizer are conveniently used in a weight ratio of about 1:0.5 to about 1:50, conveniently about 1:1 to about 1:50, and preferably in a weight ratio of about 1:4 to 1:15. A weight ratio range of 1 0 about 1:6 to about 1:10 is especially preferred.
A preparation which is suitable for the manufacture of a copper oxinate solution in an organic solvent is obtained by mixing the copper oxinate with the 15 solubilizer. Such a solution can be manufactured either by diluting the mixture, which is obtained by mixing the copper oxinate with the solubilizer. with the solvent or by mixing the copper oxinate, the solubilizer and the solvent with one another, optionally while heating. The 20 dissolution process is accelerated by heating (depending on the solvent, for example, to temperatures between about 0 C and 120 0
C).
Solutions of copper oxinate with very different copper 25 oxinate contents, up to about 15% copper oxinate, can be manufactured in this manner. Preferred solutions are those having a content between about 1 and 10 wt.%.
As solvents there come into consideration industrial 30 solvents which are usual for similar products, for example aliphatic and aromatic hydrocarbons, ketones, esters, lactones and the like. Examples of such solvents are SOLVESSO® 100 which consists of alkylbenzenes, SOLVESSO® 200 which consists of alkylnaphthalenes, Sangajol which consists of aliphatic and aromatic hydrocarbons, benzyl alcohol, methyl isobutyl ketone, y-butyrolactone and propylene glycol monomethyl ether acetate (DOWANOL® PMA).
Ji 6 0i I I 60.0 4 The solutions manufactured in accordance with the present invention can be used directly as finished solutions or, after dilution with solvents, prefetibly mineral oils, according to conventional application methods such as e.g. dipping, spraying, brushing etc. By adding emulsifiers to the solutions obtained in accordance with the invention there are obtained emulsifiable concentrates which can be applied after dilution with water.
Example 1 o 15 A green-blue solution of copper oxinate is obtained by o* stirring 10 parts of copper oxinate. 60 parts of an about equimolar mixture of mono-2-ethyl-hexyl-phosphate and di-2-ethyl-hexyl-phosphate and 30 parts of ethylene glycol phenyl ether at 80 0
C.
Example 2 o a* a* 0 A deep blue-green solution of copper oxinate is obtained by stirring a mixture of 8 parts of copper oxinate, 60 parts of an about equimolar mixture of the phosphates referred to in Example 1 and 32 parts of benzyl S alcohol at 120 0 C for 2 hours.
000I Example 3 2 parts of copper oxinate, 45 parts of monobutyl phosphoric acid ester, 33 parts of SOLVESSO® 100 (alkylbenzene mixture) and 20 parts of nonylphenol polyethoxylate are stirred at room temperature for about 1 hour until all of the copper oxinate has dissolved.
There thus results a greenish, clear solution which, because of the emulsifier content (nonylphenol polyethoxylate), can be diluted with water.
