Soapstock is a byproduct generated during the production of biodiesel from oils or fats through a process called transesterification. It consists mainly of glycerin, unreacted oils, and various impurities, including soaps formed during the reaction. Soapstock can be further processed for the recovery of valuable components or used as a feedstock in animal feed, or for other industrial applications. Its management and utilization are important for the overall sustainability of biodiesel production.

How do you determine the FFA in soapstock?
To determine the Free Fatty Acids (FFA) in soapstock, a common method is the titration approach. This involves dissolving a known amount of soapstock in a solvent, typically ethanol or a hexane-ethanol mixture, and then titrating it with a standardized sodium hydroxide (NaOH) solution. The endpoint is indicated by a pH indicator, and the amount of NaOH used allows for the calculation of the FFA content. The results are usually expressed as a percentage of oleic acid or another relevant fatty acid.
What is the best use of soap stock and how to turn it into powder and can it be a exported and usage of soapstock powder?

What are the uses of soapstock?
Soapstock, a byproduct of vegetable oil refining, is used in various industries such as livestock feed production, biodiesel manufacturing, and soap making. It can also be processed to recover valuable components like fatty acids and glycerin for further use in other products.
How do you produce soy acid oil from soapstock?
la borra o jabón se hace reaccionar con acido sulfurico en forma estequiometrica mas un exceso de 20%, a una temperatura de 70-80°c, se agita durante un par de horas y se deja decantar el agua, luego de eliminar el agua se lava con mas agua hasta que esta de un pH superior a 5, para comprobar que a reaccionado todo el ácido se puede determinar el contenido de jabón remanente en el ácido graso formado.
