Methods for making asymmetrical triazines are provided. The methods comprise first forming a mixture of at least two primary amines then reacting the mixture with an aldehyde. Methods for removing sulfides from hydrocarbon streams are also provided. The triazines may be added to the hydrocarbon stream in a molar ratio of triazine:H

Methods for making asymmetrical triazines are provided. The methods comprise first forming a mixture of at least two primary amines then reacting the mixture with an aldehyde. Methods for removing sulfides from hydrocarbon streams are also provided. The triazines may be added to the hydrocarbon stream in a molar ratio of triazine:H2S of about 10:1 to about 1:2 wherein R1, R2, and R3 are chosen from alkyls, hydroxyl-substituted alkyls, and alkoxy-substituted alkyl of 1 to 10 carbon atoms, with the proviso that R1, R2, and R3 are not all the same.
