Abstract

Vegetable oil-based raw materials are the most important renewable feedstock for chemical industries in all the time.
A tremendous shift has been observed from petrochemical-based and synthetic feedstock toward oleochemical-based products.
That’s why it has Become necessary to cultivate more oil crops containing fatty acids with interesting and desired properties
for their utilization In chemical industries, simultaneously increasing the agricultural biodiversity. Fatty acid dimers are a
class of important intermediates that are frequently used in various industrial applications such as development of polyamides,
polyurethanes, polyesters, adhesives, lubricants, paints, and coatings. This paper is focused on study of various methods used
for the synthesis of fatty acid dimers, and the effect of process parameters, namely, temperature, pressure, catalyst concentration,
and molecular distillation of dimerized products along with their industrial applications.
