“…However, most of the research focuses on C 8 alcohols [71], especially 1-octanol [72,73] and 2-ethyl-hexanol [74,75], because they are the cheapest among the higher chain alcohols (C 8 to C 14 ) [76].…”

“…In addition, integrating biolubricant production into the biodiesel industry could provide benefits such as lower operating costs and/or higher profits by producing a wider range of value-added biobased products for lubricant formulations. In their study, Rios et al [71] proposed a flexible multipurpose industrial plant configuration to produce both biodiesel and biodegradable base oils for lubricating oils. The base oils were synthesized from ricinoleic acid (obtained from castor oil) using C 8 alcohols (where 1-octanol and 2-ethyl-1-hexanol achieved 98% and 95% conversion, respectively) via esterification, epoxidation, and oxirane ring-opening reactions.…”

Biodiesel has established itself as a renewable fuel that is used in transportation worldwide and is partially or in some cases completely replacing conventional fuels. Chemically, biodiesel is a fatty acid monoalkyl ester (FAAE). Generally, the term biodiesel refers to the fatty acid methyl or ethyl esters (FAME or FAEE). Herein, an overview of the research on the synthesis of FAAE in which the alkyl moiety is a C3+ alkyl chain (branched/unbranched) is given. In addition, a comparison of the properties of the aforementioned FAAE with each other, with FAME and FAEE, and with fuel standards is given. The length of the alkyl chain has a major influence on viscosity, while pour point temperatures are generally lower when branched alcohols are used, but the fatty acid part of the molecule also has a major influence. The development of new pathways for the synthesis of higher alcohols from biomass opens a future perspective for the production of long chain FAAE as biofuels, fuel additives, or biolubricants. Due to their properties, FAAEs produced from C3–C5 alcohols have the potential to be used as fuels, while all C3+ FAAEs can be used as valuable bioadditives, and C8+ FAAEs can be used as biolubricants and viscosity improvers.

“…Thus, the environmental contamination caused by discharging waste cooking oil into water or soil can be avoided. Epoxidized vegetable oil (EVO) can be extensively utilized as a feedstock to synthesize polyols, glycols, and carbonyl compounds for the production of biolubricants, − biodiesel, − polyols for polyurethanes, − plasticizer, − resins, − cross-linked polymers, − pressure sensitive adhesives, , printing ink, and protective coatings. , The biobased lubricants produced from vegetable oil epoxidation are degradable with better lubricity, higher viscosity, and pour point as well as a lower viscosity index. , The biobased polyols have high average hydroxyl group functionality and thus ensure the production of rigid polyurethanes with high dimensional as well as good mechanical and thermal stability …”

Epoxidized vegetable oils obtained from either edible or nonedible vegetable oil have drawn extensive attention ascribing to the inherent nature of good biodegradability, renewableness, nontoxicity, and environmental friendliness. It has a broad application in the chemical industry, e.g., biolubricants, polyurethane, cross-linked polymers, coatings, and biodiesel. Currently, it is produced industrially by a homogeneous epoxidation process using in situ formed peracarboxylic acid. However, this method gives poor selectivity toward epoxides and causes severe corrosion to reactors. Efficient and recyclable heterogeneous metal-based materials have become promising alternatives for vegetable oil epoxidation due to the good activity and selectivity in the absence of any corrosive acids. Hence, the development of highly active, selective, and stable heterogeneous catalysts for the epoxidation of vegetable oils and their derivatives has becoming a major task for both academic and industrial communities. In this work, we have reviewed and summarized the most recent progress of catalysts development in the aspects of catalysts preparation, morphology, reusability, structure−function relationship, and reaction mechanism in the past five years. The effects of solvent, oxidant, type of reactor, and operating conditions as well as the reaction kinetics will also be reviewed and discussed to provide guidance for the future study of vegetable oil epoxidation.
