Comments:

Fatty acid is Oleic or tall oil. Morpholine can be used for amine.

Procedure:

Charge water to the reactor and then add other ingredients while agitating. Seal the reactor while continuing to agitate and commence heating  to a temperature of 125-135oC. Maintain temperature and pressure with agitation for 15-30 minutes. Remove heating and begin cooling . For best results cooling is done quickly (shock cooling) while releasing pressure through an external heat exchanger such as a coil or plate heat exchanger. Rapid cooling, especially through the transition point of the wax, ensures a  fine particle size emulsion is formed..

Following cooling to room temperature a bactericide can be added to aid shelf life of the emulsion. The emulsion should then be discharged and filtered.
