Abstract
Oilseeds are a significant source of raw materials for industry. Because of the overuse of edible fixed oil of plant origin in cosmetics, paints, and other manufacturing industries, the price of edible oils has increased, creating a considerable imbalance between the domestic and industrial markets. Local production of industrial intermediates such as alkyd resins is necessary to lessen import dependency. Alcoholysis methods were used to prepare alkyd resin from under-utilized seed oil of Gossypium hirsutum using maleic and phthalic anhydride. The prepared alkyd resins were characterized, and their physiochemical and chemical stability were compared to industrial grade commercial alkyd resin. Alkyd resin prepared from seed oil and maleic anhydride (COTMA) has the highest yield of 70.44%, compared to the one made from phthalic anhydride (COTPA) at 58.88%. The two alkyds show better total solids between 82.68–85.75% compared to 51.56% for commercial alkyd resin indicating possibilities of getting paint from the prepared alkyd. The alkyd formed also shows comparable drying time (60–75 mins) relative to the commercial counterpart (70 mins). Fourier-transform infrared (FT-IR), UV-Visible and 1H Nuclear Magnetic Resonance (1H NMR) spectroscopy were used to characterize the modified products (confirming a successful reaction). The study shows G. hirsutum seed oil can replace dietary vegetable oils currently used in the vegetable oil-dependent industries.
