“…However, the renaissance of this oil happened in the last decade, which can be characterised by the huge amount of studies devoted to false flax. Various applications of camelina oil have been demonstrated, e.g., as a fuel for diesel transport engines (Bernardo et al, 2003) and raw material used for synthesis of biodiesel (Yang et al, 2016), hydrocarbon fuel for jets (Zhao et al, 2015) and alkyd resins (Nosal et al, 2015). Camelina sativa oil is applied for production of potential adhesives containing epoxide (Kim et al, 2015) or acrylate and hydroxyl functionalities .…”

Camelina sativa is well known due to high content of polyunsaturated fatty acids in its oil. Till now this oil has been studied mainly for applications as raw material for synthesis of resins, biodiesel and hydrocarbon fuels. This study examines the oxidative stability of cold-pressed Camelina sativa (also known as camelina, false flax or gold-of-pleasure) oil and its extracts of spices. Despite the high content of polyunsaturated fatty acids, Camelina sativa oil appeared more rigid against oxidation than rapeseed or flax oil. Extracts of different spices were prepared by maceration in camelina oil at room temperature for 24 h. The stability of extracts was determined under accelerated oxidation conditions and monitored by peroxide values. Most of the tested additives (e.g., bay leaves, allspice, clove, barley sprouts, coriander, ginger) did not influence or even decreased oxidative stability of the oil. However, oil with thyme additive demonstrated remarkably higher stability then Camelina sativa oil alone. Press-cakes of camelina seeds were extracted with two polar solvents (ethanol or water) and their mixtures under variable conditions (room temperature or reflux). Prepared polar extracts of press-cakes were characterised by total polyphenol content (Folin–Ciocalteu method) and antiradical activity against 1,1-diphenyl-2-picryl hydrazyl and galvinoxyl.

“…These catalysts release different anions in the reaction media, however, resulting in the same selectivity to diglycerol (75%) when the glycerol conversion was 50% [45]. Nosal et al [50] also reported glycerol polymerization in the presence of LiOH as a catalyst aiming at producing only di-and triglycerols by tuning the operational conditions. After 7 h of reaction, glycerol conversions of 24% and 80% with selectivities of 100% and 68% to di-and triglycerol were actually obtained in the presence of 0.1 wt.% LiOH at 230 • C and 260 • C, respectively.…”

Polyglycerols (PGs) are biocompatible and highly functional polyols with a wide range of applications, such as emulsifiers, stabilizers and antimicrobial agents, in many industries including cosmetics, food, plastic and biomedical. The demand increase for biobased PGs encourages researchers to develop new catalytic systems for glycerol polymerization. This review focuses on alkaline homogeneous and heterogeneous catalysts. The performances of the alkaline catalysts are compared in terms of conversion and selectivity, and their respective advantages and disadvantages are commented. While homogeneous catalysts exhibit a high catalytic activity, they cannot be recycled and reused, whereas solid catalysts can be partially recycled. The key issue for heterogenous catalytic systems, which is unsolved thus far, is linked to their instability due to partial dissolution in the reaction medium. Further, this paper also reviews the proposed mechanisms of glycerol polymerization over alkaline-based catalysts and discusses the various operating conditions with an impact on performance. More particularly, temperature and amount of catalyst are proven to have a significant influence on glycerol conversion and on its polymerization extent.

“…However, the virgin oil alkyd ink vehicle and commercial alkyd ink vehicle had a lower AV value than vehicles derived from waste oil. AV value is an important aspect of alkyd resin because resin with a high AV value forms a coating very slowly or not at all [28]. Viscosities of the alkyd ink vehicles showed ratio dependence on the phthalic anhydride contents due to higher conversion of the acidic monomers.…”

Alkyd-based printing ink vehicles were successfully prepared from waste frying oil. Three alkyd resins were synthesized using different ratios of phthalic anhydride. Properties of the 3 prepared resins were measured and compared with virgin oil alkyd resin and commercial alkyd resin. Viscosities of the obtained ink vehicles ranged from 8.6 to 34.9 poises. The vehicles were also completely compatible with carbon black for formulating black printing inks. Preliminary properties of the 3 formulated inks were evaluated and compared with black printing ink prepared from virgin oil alkyd and commercial alkyd. The formulated inks had satisfactory viscosity and tackiness as properties suitable for a variety of printing applications. The 3 synthesized inks had rub resistance values ranging from 4.61 to 5.75 %, slightly higher than the rub resistance of virgin oil alkyd ink and commercial alkyd ink. Particle fineness and water tolerance properties of the 3 formulated inks were comparable with virgin oil alkyd ink and commercial alkyd ink. Results suggested that waste frying oil has potential application as a raw material in the printing ink industry.
