Introduction

Alexssander Shigueru Araujo is a notable inventor based in Sao Jose dos Campos, Brazil. He has made significant contributions to the field of chemical engineering, particularly in the production of fatty acids and cardanol. With a total of 2 patents, Araujo's work has implications for both food supplements and biofuels.

Latest Patents

Araujo's latest patents include a process for the production of fatty acids, fatty acid esters, and sterolesters from soapstock. This innovative process involves adding a lipase directly to alkaline soapstock to facilitate the hydrolysis of glycerides without prior neutralization. The method also includes neutralizing and splitting the soaps with strong acids, followed by separating the fatty acid phase from the aqueous phase through settling or centrifugation. The fatty acids produced can be esterified with C1-C6 alcohols, leading to valuable products for food and pharmaceutical applications.

Another significant patent is the method for producing cardanol. This process involves distilling crude cashew nutshell liquid to obtain a distillate, which is then reacted with acetic anhydride. The resulting reaction mixture undergoes fractional distillation to yield a color-stable composition containing cardanol. This method also includes the production of color-stable phenalkamines, which are formed by reacting the fractional distillate with aliphatic amines and formaldehyde.
