Method of preparing a borate organic complex anion containing salt compositions

Abstract

A method of preparing a compound or formulation having biocidal or preservative properties, or both comprises reacting an organic complexing agent, preferably a selected organic alcohol, with a borate or boric acid to produce a borate organic complex ion. The complex ion is preferably further reacted with a suitable cationic species. A compound or formulation so prepared is also claimed.

What I claim is:  
     
       1. A method of preparing a salt composition having biocidal or preservative properties or both, comprising the steps of: 
       a) reacting an organic complexing agent selected from the group consisting of 1,2 diols, 1,3 diols, 1,3,5 triols and polyhydroxy macrolide-type compounds with borate or boric acid or both to produce a borate organic complex anion; and  
       b) reacting said complex anion obtained in step a) with a biocidal cationic species selected from the group consisting  of ions of copper , zinc, barium, iron, manganese, cobalt, nickels, alkyl (C 9 -C 16 ) dimethyl amines, dialkyl (C 7 -C 14 ) methyl amines, alkyl (C 9 -C 16 ) dimethyl benzyl ammonium, dialkyl (C 7 -C 14 ) dimethyl ammonium and substituted triazole compounds  to form a neutral or partially neutralized salt.  
     
     
       2. The method of claim  1 , wherein said organic complexing agent is selected from the group consisting of naphthalene diols, phenyl glycols, glycerol ethers, dihydroxy phenyl compounds, dihydroxy anthracene compounds, methylol phenols, methylol naphthols, methylol anthrols, aliphatic 1,2 diols, aliphatic 1,3 diols, and triol monoesters. 
     
     
       3. The method of claim  2 , wherein the organic complexing agent is a methylol phenol. 
     
     
       4. The method of claim  1 , wherein said biocidal cationic species are selected from the group consisting of ions of copper, zinc and barium. 
     
     
       5. The method of claim  4 , wherein said biocidal cationic species are ions of copper. 
     
     
       6. The method of claim  1 , further comprising the step of: 
       a1) dissolving wherein said organic complexing agent is dissolved in a solvent prior to step a), wherein said solvent is selected according to the hydrophobicity of at least said organic complexing agent or said borate organic complex ion.  
     
     
       7. The method of claim  6 , wherein said solvent is selected from the group consisting of white spirits, kerosene, chlorinated solvents, aromatic esters, phosphate esters and alcohols having 4 to 27 carbon atoms per molecule. 
     
     
       8. The method of claim  6 , wherein said organic complexing agent is dissolved in said solvent and a co-solvent. 
     
     
       9. The method of claim  8 , wherein said co-solvent is 1-octanol. 
     
     
       10. A method of preparing a substantially water-insoluble composition having biocidal or preservative properties or both, comprising the steps of: 
       a) dissolving an organic complexing agent comprising 2-chloro-4-(1,1,3,3-tetra methyl butyl)-6-methylol-phenol in kerosene;  
       b) reacting said organic complexing agent obtained in step a) with a borate or boric acid or both to form a borate organic complex ion; and  
       c) reacting said borate organic complex ion produced in step b) with an aqueous solution of a copper salt to produce said composition.  
     
     
       11. The method of claim  2 , wherein the organic complexing agent is a methylol naphthol. 
     
     
       12. The method of claim  2 , wherein the organic complexing agent is a methylol anthrol.
