Abstract
The present disclosure relates to a method for protecting an aldehyde and/or an alcohol from oxidation and/or from being converted into an acid comprising contacting said aldehyde and/or alcohol with a protective agent comprising a sulfur containing compound.
Claims33
A method for protecting a fatty aldehyde and/or a fatty alcohol from degradation comprising contacting said aldehyde and/or alcohol with a protective agent comprising a sulfur containing compound, wherein the fatty aldehyde and/or fatty alcohol comprises 12 to 18 carbons and comprises one or more double bonds at position 9 ((Z)-9) and/or at position 11 ((Z)-11), and wherein the protective agent comprises a conjugated sulfur.
The method of any one of the preceding claims, wherein the degradation occurs by oxidation.
The method of any preceding claims, wherein the aldehyde and/or alcohol comprises 16 carbons and has a double bond at position 9 and/or at position 11.
The method of any preceding claims, wherein the method comprises protecting a plurality of fatty aldehydes, a plurality of fatty alcohols, and/or a combination thereof.
The method of any preceeding claims, wherein the fatty aldehyde and/or fatty alcohol is a pheromone.
The method of any preceding claims, wherein the fatty aldehyde is an arthropod pheromone.
The method of any preceding claim, wherein the protective agent is a corrosion inhibitor.
The method of any preceding claim, wherein the protective agent comprises a thiol.
The method of any preceding claim, wherein the protective agent comprises a compound selected from zinc pyrithione, 5-amino-1,3,4-thiadiazole-2-thiol, 2-thiazoline-2-thiol, 5-methyl-1,3,4-thiadiazole-2-thiol, 2-mercapto-benzimidazole, 2-mercapto-1-methylimidazole and sodium pyrithione.
The method of any preceding claim, wherein the aldehyde is contacted with the protective agent by mixing the aldehyde with the protective agent into a composition.
A composition comprising a fatty aldehyde, optionally a pheromone, and a protective agent comprising a sulfur containing compound, which protects the aldehyde from degradation, wherein the fatty aldehyde comprises 12 to 18 carbons and comprises one or more double bonds at position 9 ((Z)-9) and/or at position 11 ((Z)-11), and wherein the protective agent comprises a conjugated sulfur.
