Claims
- 1. A biocidal concentrate comprising a mixture of a halopropargyl compound and a chelating agent, wherein the weight ratio of said halopropargyl compound to said chelating agent is between 1:1 to 8:1 and wherein said concentrate is useful for providing biocidal activity to an alkyd formulation containing a transition metal drier and for stabilizing the alkyd formulation against degradation of said halopropargyl compound.
- 2. The biocidal concentrate of claim 1 wherein the halopropargyl compound is an iodopropargyl derivative selected from an iodopropargyl ester, an iodopropargyl ether, an iodopropargyl acetal, an iodopropargyl carbamate and an iodopropargyl carbonate.
- 3. The biocidal concentrate of claim 2 wherein the iodopropargyl carbamate has the formula: ##STR3## where R is selected from the group consisting of hydrogen, substituted and unsubstituted alkyl groups having from 1 to 20 carbon atoms, substituted and unsubstituted aryl, alkylaryl, and aralkyl groups having from 6 to 20 carbon atoms and from substituted and unsubstituted cycloalkyl and cycloalkenyl groups of 3 to 10 carbon atoms.
- 4. The biocidal concentrate of claim 3 wherein the transition metal is cobalt.
- 5. The biocidal concentrate of claim 4 wherein the chelating agent is selected from the group consisting of ethylenediaminetetraacetic acid, ethylenediamine, acetylacetone, nitrilotriacetic acid, ethyleneglycol-bis(.beta.-aminoethyl ether)-N,N-tetraacetic acid, 2,2'-bipyridine, 1,10-phenanthroline, N,N,N',N'-tetramethyl ethylenediamine, 2-hydroxyquinoline, 8-hydroxyquinoline, 8-hydroxyquinaldine, 2-hydroxy-4-methylquinaldine, 5-chloro-8-hydroxyquinoline, 5,7-dichloro-8-hydroxyquinoline, 2,4-quinolinediol, 2-quinolinethiol, 8-quinolinethiol, 8-aminoquinoline, 4,4'-dimethyl-2,2'-dipyridyl, 2,2':6',2"-terpyridine, 4,4'-diphenyl-2,2'-dipyridyl, 2,2"-dipyridine-3,3'-diol, 4-methyl-1,10-phenanthroline, 5-methyl-1,10-phenanthroline, 4,7-dimethyl-1,10-phenanthroline, 5,6-dimethyl-1,10-phenanthroline, 3,4,7,8-tetramethyl-1,10-phenanthroline, 4,7-diphenyl-1,10-phenanthroline, 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline, 2,2'-biquinoline, 2-quinoxalinol, 3-methyl-2-quinoxalinol, 2,3-dihydroxyquinoxaline, 2-mercaptopyridine, 2-dimethylaminopyridine, 1,2-bis(dimethylphosphino)ethane, 1,2-bis(diethylphosphino)ethane, 1,2-bis(diphenylphosphino)ethane, 1,3-bis(diphenylphosphino)propane, and 1,4-bis(diphenylphosphino)butane.
- 6. The biocidal concentrate of claim 5 wherein the iodopropargyl carbamate is selected from the group consisting of 3-iodo-2-propynyl propyl carbamate, 3-iodo-2-propynyl butyl carbamate, 3-iodo-2-propynyl hexyl carbamate, 3-iodo-2-propynyl cyclohexyl carbamate, 3-iodo-2-propynyl phenyl carbamate, and mixtures thereof.
- 7. The biocidal concentrate of claim 6, wherein the iodopropargyl carbamate is 3-iodo-2-propynyl butyl carbamate and the chelating agent is 2,2'-bipyridine.
