“…In addition, according to the results of a 2019 (2016?) study in the European Coatings Journal, the use of bio-based monomers in coating applications is more important than it was five years ago, according to approximately 77% of the respondents [ 115 ].…”

Recently, due to the depletion of natural resources and raising environmental and economic concerns regarding petroleum derivatives, the creation of novel ecologically friendly and sustainable materials made from bio-based and renewable resources is gaining popularity. Alkyd resins are synthetic resins in which both renewable (fatty acids, glycerol, oil, etc.) and nonrenewable (maleic anhydride, pentaerythritol, phthalic anhydride, etc.) raw materials are used in their production. Due to their superior performance (good aging, greater weather resistance and high heat resistance, outstanding gloss, etc.) over other resins, easy application, low cost, and varied use, in the coating and paint industries, they are commonly used. This review covers the studies on bio-based monomers used instead of nonrenewable ones in the production of alkyds. The effects of substituted bio-based monomers on the final properties (adhesiveness, drying times, hardness, tackiness, etc.) of produced alkyds and coatings are also discussed in detail.

“…It blooms in different climatic conditions, is tolerant to drought, and thrives in semiarid climate environments, making its cultivation strategically important to the Brazilian economy, with Brazil being the third‐largest producer of castor beans, behind China and India. Castor bean cultivation is intensifying in these countries due to the importance of castor oil in the chemical industry and its potential as an energy source 4 …”

“…Castor bean cultivation is intensifying in these countries due to the importance of castor oil in the chemical industry and its potential as an energy source. 4 Castor oil has ricinoleic acid (12-hydroxy-9-cisoctadecenoic acid) as its major fatty acid (>80%). Ricinoleic acid is peculiar in that it has a hydroxyl group on the aliphatic chain (Figure 1).…”

In this work, ultrasound was used to assist the ethanolysis of castor oil in a solvent-free system, catalyzed by a dry fermented solid containing the lipase from Burkholderia contaminans (BCFS). Reactions were done at 45 • C. The maximum conversion in Erlenmeyer flasks was 71% in 96 h, using a loading of 9% (mass of BCFS in relation to the mass of triacylglycerols in the castor oil) and a molar ratio of ethanol:oil of 6:1, with addition of ethanol in 12 steps. In a packed-bed reactor containing 12 g of BCFS, the conversions were 78% in 48 h, and 83% in 72 h with an ethanol to oil molar ratio of 3:1 and treatment with an ultrasound probe, with maximum power of 500 W, frequency of 20 kHz, and 75% of the maximum power. These results are promising given that, with an ultrasound assisted bioreactor, a higher conversion in a shorter time was achieved, with a lower ethanol to oil molar ratio than was the case in the Erlenmeyer flasks without ultrasound.
