Onyeka Stanislaus Okwundu

Dear Romark John Brana Jerez

YES, saponification after transesterification is very possible; In fact, it undesirably occurs virtually always (in course of transesterification) with homogeneous base catalysts. Just like lipids, biodiesel (fatty acid alkyl esters) also have saponification values.

Regards!

Sameer Algburi

Absolutely possible and I support the clarification presented by Onyeka.

Osayed Sayed Mohamed Abu-Elyazeed

Yes of course my dears, since the ester is basically an oil. But why you are asking?

Carlos Alejos

Si, es posible, pero indeseado. La reación es: metilestes+NaOH->Jabon + Metanol
